Description

Technical Field

[0001] The invention relates to the field of mops, in particular to a flat mop with a wiping liquid spraying mechanism. Background Art

[0002] The hands-free mop is a cleaning component that cleans and squeezes water from a mop cloth through a water squeezing mechanism. It is widely welcomed by users because it does not require the mop cloth to be removed from the mop head of the mop for cleaning.

[0003] However, in actual use, the mop cloth of the mop is only cleaned by clean water in a tap or a bucket, and the stains such as oil stains on the mop cloth cannot be cleaned. If a cleaner cleaning is required, a cleaning agent needs to be added to the mop cloth.

[0004] For example, Chinese patent CN202122497931.5 relates to a hands-free water spray mop, which has a liquid storage unit on a fixed unit, a water outlet seat fixed to a scraper seat, a water outlet of the water outlet seat corresponding to the scraper, and a hole corresponding to the water outlet is arranged on the scraper. The action unit controls the liquid spraying part to spray the liquid of the liquid storage unit from the water outlet and the hole, and the cleaning unit can be cleaned when passing through the scraper.

[0005] For example, Chinese patent CN202323668799.5 relates to a flat mop, a water-wiping outlet corresponding to the mop head is provided on the water-wiping rack of the flat mop, a pump pressure assembly is provided inside the water-wiping rack, and the water-wiping outlet is provided on the side of the cleaning surface facing the mop head. The liquid storage tank and the pump pressure assembly are both arranged on the water-wiping rack, and the pump pressure assembly is respectively connected to the water outlet and the liquid storage tank pipeline. The pump pressure assembly can absorb liquid from the liquid storage tank and drive the liquid to be discharged to the cleaning surface of the mop head through the water outlet.

[0006] The above-mentioned mops are all provided with a water outlet on the water-sweeping frame, and the pump pressure assembly is controlled at the position of the mounting part to spray liquid to the wipes for cleaning. The water-sweeping frame and the guide part need to be provided with separate spaces to install the components of the liquid spray assembly, which is complex in structure and cumbersome to install. In addition, when testing the liquid spraying function of the liquid spray assembly at the factory, the water-sweeping assembly and the liquid spray assembly need to be inspected as a whole, which is inefficient. If the inspection fails, the disassembly and assembly of the water-sweeping assembly and the liquid spray assembly is also troublesome. Therefore, the structure of the liquid spray assembly on the mop needs to be further optimized. Summary of the invention

DETAILED DESCRIPTION

[0054] The following describes the embodiments of the present invention in detail in conjunction with the accompanying drawings, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

The term "multiple" used herein refers to two or more numbers. The terms "vertical", "horizontal" and the like as used herein refer to a substantially vertical or substantially horizontal state within a reasonable error range and do not necessarily have to be very precise.

[0056] like Figure 1-28 A flat mop with a wiping material spraying mechanism comprises a rotatably connected mop rod 1 and a mop head 2, a wiping material 3 is arranged on the mop head 2, the mop rod 1 is provided with a water squeezing device 4 which can move up and down, the water squeezing device 4 comprises a water squeezing sleeve 5, a water squeezing frame 6 and a liquid spraying mechanism 7, the water squeezing frame 6 is provided with a squeezer 8 for cleaning the wiping material 3, the mop head 2 is rotated to a direction roughly parallel to the mop rod 1, the water squeezing device 4 moves up and down along the mop rod 1 to a preset position, the liquid spraying mechanism 7 can spray cleaning liquid onto the wiping material 3, and the squeezer 8 follows the water squeezing device 4 to move to clean the wiping material 3.

[0057] The connection structure of the mop rod 1 and the mop head 2 in the present invention adopts a common connection structure in the prior art. The patent document with publication number CN208355360U discloses the technical features of the mop rod and the mop head, that is, the mop rod and the mop head are connected by a steering mechanism. Through the steering mechanism, the mop head can move freely forward, backward, left and right relative to the mop rod. The steering mechanism can also keep the mop head and the mop rod in a vertical and parallel position. The present invention will not repeat the connection structure of the mop rod and the mop head.

[0058] The cleaning liquid sprayed by the liquid spraying mechanism 7 in the present invention is a general term and does not specifically refer to ordinary cleaning liquid. It can be a cleaning liquid such as dishwashing liquid, hand soap, laundry detergent, etc. that is directly used to clean items or is used in combination with water to clean items. It can also be a liquid used for sterilization and disinfection such as alcohol and disinfectant. It can also be a liquid used to remove odors and increase fragrance. Of course, it can also be ordinary water. By spraying water to increase the wetness of the wipe 3 or the ground, the above-mentioned liquids can be sprayed on the wipe 3 or the ground to improve the cleaning effect of the wipe 3 or the ground.

[0059] The water squeezing device 4 of the present invention comprises a water squeezing jacket 5, a water squeezing frame 6 and a liquid spraying mechanism 7. Specifically, Figure 2 The top of the water squeezing sleeve 5 is set as a tube sleeve, which can be set on the outer surface of the mop rod 1 and move up and down along the mop rod 1. The bottom of the water squeezing sleeve 5 is fixedly connected to the water squeezing frame 6, and the lower end of the water squeezing sleeve 5 can be a tube sleeve also set on the outer surface of the mop rod 1; Figure 3 The lower end of the water squeezing jacket 5 may also be a connecting rod 9 extending up and down outside the mop rod 1. Figure 4 The squeezing frame 6 is provided with an extrusion port 10 and a rod port 11 which penetrate upward and downward, and the extrusion port 10 and the rod port 11 are horizontally connected. The extrusion port 10 is used for the mop head 2 and the wiping object 3 to pass through upward and downward when cleaning. The rod port 11 is sleeved on the outer surface of the mop rod 1. When the mop head 2 and the wiping object 3 enter the extrusion port 10, the front and rear sides of the squeezing frame 6 can simultaneously support the mop rod 1, the mop head 2 and the wiping object 3. The upper end of the squeezing frame 6 is fixedly connected to the lower end of the squeezing sleeve 5 to form an integral squeezing device 4.

[0060] In the present invention, the liquid spraying mechanism 7 includes a pressing portion 12, a liquid storage chamber 13 and a liquid spraying port 14. The liquid storage chamber 13 is used to store cleaning liquid. The pressing portion 12 is used to control the cleaning liquid to be sprayed out from the liquid spraying port 14 and sprayed onto the wiping object 3 or the ground. The upper end of the water squeezing sleeve 5 forms a water squeezing handle 15 for the user to hold to push and pull the water squeezing device 4 up and down. The liquid spraying mechanism 7 is installed on the water squeezing handle 15 or the water squeezing sleeve 5 is located below the water squeezing handle 15 to provide a clearance area for the user's hand to hold. When the flat mop is used to clean the wiping object 3, one hand is generally held on the upper end of the mop rod 1, and the other hand is held on the water squeezing handle 15, and the water squeezing handle 15 is pushed and pulled up and down to achieve relative movement and cleaning between the water squeezing device 4 and the wiping object 3. The position setting of the liquid spraying mechanism 7 makes it convenient for the user to hold the water squeezing handle 15 to push and pull the water squeezing device 4 to clean the wipe 3, while controlling the liquid spraying mechanism 7 to spray cleaning liquid onto the wipe 3 to further clean or wet the wipe 3, thereby realizing the work of spraying liquid onto the wipe 3 and cleaning the wipe 3 simultaneously with one hand operation.

[0061] The specific usage is as follows: Figure 5, the squeezing device 4 is positioned at a high position of the mop rod 1, and the mop head 2 is rotated to a position perpendicular to or inclined with the mop rod 1. At this time, the flat mop can be used to clean the floor; the mop head 2 is rotated to a position roughly parallel to the mop rod 1, and the squeezing device 4 is pushed downward, and the mop head 2 and the wiping material 3 enter the squeezing port 10 upward, and the squeezer 8 cleans the wiping material 3, and at the same time, the pressing part 12 is controlled to spray the cleaning liquid onto the wiping material 3 to improve the cleaning effect.

[0062] In the present invention, the direction facing the wipe 3 is the front direction, and the direction away from the wipe 3 is the rear direction. The squeezer 8 and the liquid spraying port 14 are both located in front of the water squeezing device 4. Preferably, when the wipe 3 is parallel to the mop rod 1, the squeezer 8 and the liquid spraying port 14 are both located in front of the wipe 3, so that the squeezer 8 can contact the wipe 3 for cleaning and squeezing water, and the movement resistance between the squeezer 8 and the wipe 3 will not be too large, and space can also be provided for the liquid spraying port 14 to spray liquid on the wipe 3. Example 1

[0063] In this embodiment, the entire water squeezing sleeve 5 and the main body of the water squeezing frame 6 are made of plastic material in one piece. The lower end of the water squeezing sleeve 5 is provided with a clearance groove 16 for the mop head 2 to move. The main body of the water squeezing frame 6 is equipped with an extruder 8 and a support member 17 to clamp the mop head 2 together. The mop rod 1 and the mop head 2 can pass through the rod opening 11 and the extrusion opening 10 respectively at the same time. The extruder 8 cleans or squeezes water from the wiping material 3 entering the extrusion opening 10.

[0064] In this embodiment, Figure 7 The liquid spraying mechanism 7 includes a shell 18, a cavity is provided in the shell 18 to form a liquid storage chamber 13 or the liquid storage chamber 13 is installed in the shell 18, the pressing portion 12 and the liquid spraying port 14 are also arranged on the shell 18, so that the shell 18, the pressing portion 12, the liquid storage chamber 13 and the liquid spraying port 14 form a liquid spraying module as a whole, the pressing portion 12 can be installed on the liquid storage chamber 13 and then installed on the shell 18 together with the liquid storage chamber 13, the liquid spraying port 14 can be a separate component, or a port for spraying liquid can be provided on the shell 18, the water squeezing jacket 5 is provided with a mounting platform 19 on the water squeezing handle 15 or below the water squeezing handle 15, and the liquid spraying mechanism 7 is installed on the water squeezing jacket 5 through the mounting platform 19.

[0065] Preferably, in order to facilitate the inspection and replacement of the liquid spraying mechanism 7, during production and installation, the pressing portion 12, the liquid storage chamber 13, the liquid spraying port 14 and the housing 18 are assembled into a complete liquid spraying module, and then the liquid spraying module is installed on the installation platform 19. Since each liquid spraying mechanism 7 needs to be inspected for liquid spraying during production assembly or inspection, the liquid spraying mechanism 7 that passes the inspection can be installed on the installation platform 19, and the liquid spraying mechanism 7 that fails the inspection needs to be repaired or destroyed. The complete liquid spraying module is set up, and the liquid spraying module can be inspected for liquid spraying separately. In the prior art, the liquid spraying mechanism is associated with the water squeezing device, that is, some parts of the water squeezing device form some parts of the liquid spraying mechanism. During production inspection, the complete water squeezing device or even the complete flat mop as a whole needs to be inspected for liquid spraying. Because the inspected parts are large, the inspection is more troublesome and the inspection efficiency is low. Compared with the liquid spraying mechanism in the prior art, the assembly, inspection and repair of the liquid spraying mechanism 7 and the water squeezing device 4 in this embodiment are simpler and less costly.

[0066] In this embodiment, Figure 2 and Figure 5 The liquid spraying mechanism 7 and the water squeezing rack 6 are independent, and the independence includes functional independence and structural independence. Functional independence means that the liquid spraying function of the liquid spraying mechanism 7 and the cleaning and squeezing function of the water squeezing rack 6 are independent. Regardless of whether the liquid spraying mechanism 7 and the water squeezing device 4 are installed as a whole, the liquid spraying function of the liquid spraying mechanism 7 and the squeezing function of the water squeezing rack 6 can be realized separately. Preferably, the liquid spraying mechanism 7 is detachably installed on the squeezing sleeve 5 as a whole. When the liquid spraying mechanism 7 is installed on the squeezing sleeve 5, the flat mop can have the liquid spraying function and the cleaning and squeezing function of the wipe 3 at the same time. When the liquid spraying mechanism 7 is disassembled, the flat mop still has the cleaning and squeezing function of the wipe 3. The disassembled liquid spraying mechanism 7 can still be used as a liquid spraying bottle to spray liquid on other objects.

[0067] like Figure 5 , structurally independent, that is, there is no other connection between the entire liquid spray mechanism 7 and the entire water squeezing frame 6 except the connection relationship with the water squeezing jacket 5. The entire liquid spray mechanism 7 is located directly above the extruder 8, and there is no water connection and control connection between the liquid spray mechanism 7 and the water squeezing frame 6. There is a distance between the liquid spray mechanism 7 and the water squeezing frame 6 or between the liquid spray port 14 and the water squeezing frame 6, and the distance forms a spray area 20.

[0068] In the above embodiment, if Figure 5The shell 18 extends toward the squeezing rack 6, and the liquid spraying port 14 is arranged at the end of the extended section of the shell. The extended section of the shell forms a liquid storage chamber 13, that is, the liquid spraying direction of the liquid spraying port 14 is roughly parallel to the extending direction of the mop rod 1. When the squeezing device 4 moves downward along the mop rod 1, the mop head 2 and the wiping material 3 move upward relative to each other, and the wiping material 3 passes through the squeezing port 10 upward into the spraying area 20 until it moves to a height where the bottom of the liquid spraying mechanism 7 is close to or at least partially overlaps with the top of the wiping material 3. When the wiping material 3 enters and leaves the spraying area 20, or when the wiping material 3 moves to a preset highest position, the pressing portion 12 controls the liquid spraying port 14 to spray cleaning liquid into the spraying area 20 for the wiping material 3 to self-clean.

[0069] When a general flat mop is used to clean the wipe 3, the wipe 3 is usually pointed upward toward the faucet. Based on this usage habit, the liquid spray port 14 in this embodiment is exposed and does not fit the wipe 3. The cleaning liquid may fall onto the wipe 3 due to the spray force and gravity.

[0070] like Figure 6 In order to prevent the user from accidentally touching the pressing portion 12 or spraying liquid when the wiping object 3 is facing downward, so that the cleaning liquid cannot be sprayed onto the wiping object 3, the liquid spraying port 14 can also be set at an angle so that the cleaning liquid can still flow to the wiping object 3 according to its inertia after leaving the liquid spraying port 14, so that the cleaning liquid can be sprayed onto the wiping object 3 regardless of the angle at which the flat mop is controlled.

[0071] Compared with the liquid spraying port 14 being arranged to be in contact with or in contact with the wipe 3, the cleaning liquid in this embodiment first passes through the outside air after leaving the liquid spraying port 14, and then falls on the wipe 3. Whether the liquid spraying mechanism 7 sprays liquid and the amount of liquid spraying can be observed through the movement of the cleaning liquid in the outside air and the situation of falling on the wipe 3, so that the user can adjust the liquid spraying size of the liquid spraying mechanism 7 and replenish the cleaning liquid to the liquid storage chamber 13. At the same time, the liquid spraying port 14 and the wipe 3 contact the liquid spraying mode, and the dust and dirt on the wipe 3 are easy to block the liquid spraying port 14, affecting the liquid spraying effect.

[0072] In order to illustrate the situation that the liquid spraying mechanism 7 and the water squeezing frame 6 are independent and the situation of the position of the spraying area 20, as shown in FIG. Figure 5 and Figure 8, the length of the squeezing device 4 is X, the length of the mop head 2 or the wiping material 3 is Y, the distance between the liquid spraying port 14 and the squeezing rack 6 is Z, and the space where the distance length Z is located is the spraying area 20, which is used for movement during the spraying of the cleaning liquid and for the user to observe the liquid spraying state. The length X is greater than the length Y to avoid contact between the hand and the wiping material 3 during the movement of the squeezing device 4, and to avoid the sprayed cleaning liquid from falling onto the squeezing rack 6 or even falling onto the ground over the squeezing rack 6, the length Z in this embodiment is set to be greater than half of the length Y. The lengths X, Y, and Z in this embodiment are all as shown in FIG. Figure 8 The horizontal length of the flat mop in the state shown. It should be noted that if the squeezing device 4, the mop head 2, and the wiping material 3 are adjustable in length or foldable, only the lengths of the squeezing device 4, the mop head 2, and the wiping material 3 under normal cleaning and squeezing conditions are compared; the length Z generally refers to the distance between the top of the squeezing frame 6 (excluding the squeezing jacket 5) and the part of the liquid spraying mechanism 7 closest to the squeezing frame 6. If most of the parts of the squeezing device 4 are located above the squeezing jacket 5 and the liquid spraying port 14 is located in the squeezing frame 6, the length Z is zero or even a negative length.

[0073] In the above embodiment, when the squeezing device 4 moves to the lowest position relative to the mop head 2, that is, when the mop head 2 and the wiping material 3 move upward to the highest position, the spraying mechanism 7 and the wiping material 3 have an overlapping area along the plane perpendicular to the mop rod 1, or the two do not overlap at all, such as Figure 5 and Figure 8 , which are schematic diagrams of the liquid spraying mechanism 7 and the wiping object 3 having an overlapping area and a non-overlapping area, respectively.

[0074] In other embodiments, the liquid spraying port 14 may also be arranged at a position of the housing 18 close to one side of the wiping material 3, and when the liquid spraying port 14 moves with the water squeezing device 4 to coincide with any position of the wiping material 3, the liquid spraying port 14 sprays liquid onto the wiping material 3. In this liquid spraying mode, a spacing for the mop head 2 and the wiping material 3 to enter needs to be set between the water squeezing sleeve 5 and the liquid spraying mechanism 7, and the spacing forms a spraying area 20, and the thickness of the spraying area 20 is adapted to the thickness of the mop head 2 plus the wiping material 3. When the liquid spraying port 14 partially coincides with the wiping material 3, the liquid spraying port 14 is attached to the wiping material 3 or there is a liquid spraying gap between the liquid spraying port 14 and the wiping material 3. In this spraying mode, the area of ​​the wiper 3 available for spraying is related to the moving overlapping length of the wiper 3 and the spray port 14, and the width of the spray port 14. If there is an area where the cleaning liquid is not sprayed, the squeezer 8 moves relative to the wiper 3 to spread the cleaning liquid evenly and bring it to the area where the cleaning liquid is not sprayed, so that the wiper 3 can receive the cleaning liquid as a whole.

[0075] Compared with the existing liquid spraying mechanism, the liquid spraying mechanism 7 in the present embodiment is more integrated and simpler. There is no need to set a separate cavity in the water squeezing jacket 5 and the water squeezing frame 6 for installing the water circuit, thereby simplifying the installation structure of the water squeezing device 4 and the liquid spraying mechanism 7 to improve the production and assembly efficiency. At the same time, the water circuit of the liquid spraying mechanism 7 is independent of the water squeezing jacket 5 and the water squeezing frame 6, which can avoid the situation where the water circuit in the water squeezing jacket 5 and the water squeezing frame 6 is compressed or stretched due to the up and down movement of the water squeezing device 4, resulting in bending and clogging. Of course, after the liquid spraying mechanism 7 in the present embodiment is set as an independent liquid spraying module, it is also possible to adopt a method where no water circuit is set and the cleaning liquid is directly sprayed from the liquid storage chamber 13 through the liquid spraying port 14.

[0076] In the above embodiment, the portion of the water squeezing frame 6 located at the front side of the extrusion port 10 has a certain thickness, which can increase the overall strength of the water squeezing frame 6 to prevent the water squeezing frame 6 from deforming outward when the mop head 2 and the wiping material 3 enter the extrusion port 10. The space formed by the thickness of the front side of the water squeezing frame 6 can also be used to install the squeezer 8.

[0077] Preferably, the front side of the squeezing rack 6 is provided with an intercepting portion 21, which extends to the front side and can block the liquid that is about to leave the wipe 3, preventing the liquid from moving to the ground, wall, or other places where the liquid is not needed. The intercepting portion 21 in this embodiment is perpendicular to the wipe 3 during squeezing, or the intercepting portion 21 is tilted in a manner that the front end is high and the rear end is low. If the intercepting portion 21 is set in a manner that the front end is low and the rear end is high, no matter the inclined surface is a straight surface or a curved surface, the cleaning liquid can easily flow to the outside along the extension direction of the intercepting portion 21. The intercepting portion 21 in this embodiment can be arranged in the following ways: The first type: Fig. 9 The intercepting portion 21 is arranged outside the front of the water squeezing rack 6, that is, a heightened convex portion is arranged in front of the water squeezing rack 6, and the intercepting portion 21 and the surface angle area of ​​the water squeezing rack 6 form a temporary storage area 22. The intercepting portion 21 can also be arranged in a manner perpendicular to or inclined to the wipe 3. In order to prevent the liquid in the temporary storage area 22 from flowing out and being used to clean the wipe 3, a reflux hole 23 can be arranged at any one or more of the three positions of the intercepting portion 21, the water squeezing rack 6, and between the intercepting portion 21 and the water squeezing rack 6. The liquid in the temporary storage area 22 can flow into the extrusion port 10 through the reflux hole 23 to clean the water squeezing rack 6, the squeezer 8 or the wipe 3, and the external cleaning water can also enter the water squeezing rack 6 through the reflux hole 23 to clean the water squeezing rack 6, the squeezer 8 or the wipe 3.

[0078] The second type: Fig.10The intercepting portion 21 is arranged at the top of the front side of the water squeezing rack 6, or the top surface of the front side of the water squeezing rack 6 forms the intercepting portion 21, and the intercepting portion 21 blocks part of the liquid and forms a temporary storage area 22 above the intercepting portion 21; and when the intercepting portion 21 is arranged obliquely, the angle area between the intercepting portion 21 and the wipe 3 forms the temporary storage area 22, and the temporary storage area 22 can intercept and store more liquid. At the same time, in general usage habits, the inclined intercepting portion 21 is more vertical, and its diversion effect is better. Similarly, the intercepting portion 21 can also be provided with a reflux hole 23 that runs through the top and bottom, and the liquid in the temporary storage area 22 can flow into the extrusion port 10 or the water squeezing rack 6 through the reflux hole 23 to clean the wipe 3, and the external cleaning water can also enter the water squeezing rack 6 through the reflux hole 23 to clean the water squeezing rack 6, the squeezer 8 or the wipe 3.

[0079] The third type, such as Fig.11 The above two interception parts 21 are provided at the same time to achieve a better interception effect.

[0080] Preferably, the intercepting portion 21 is in the form of a flat surface or a shape in which the rear end is lower than the front end, so as to improve the intercepting and diverting effects.

[0081] In the above embodiment, when the flat mop is being cleaned and squeezed, the squeezer 8 squeezes the wiper 3 while the squeezer device 4 moves downward relative to the wipe 3. The water in the wipe 3 is driven by the squeezer 8 to flow downward. The squeezer frame 6 is provided with a drainage hole 24 below the interception portion 21. The drainage hole 24 and the reflux hole 23 are independent. The water generated by the squeezer 8 when cleaning and squeezing the wipe 3 flows out through the drainage hole 24 and below the squeeze port 10.

[0082] Specifically, Fig.12 The squeezer 8 is provided with an inclined track 25, and the two ends of the squeezer 8 are movably mounted on the inclined track 25 through the protruding columns 26. When washing or squeezing water, the squeezer 8 is moved by the wipe 3 to adjust the tightness between the squeezer 8 and the wipe 3, such as Fig.10 , the squeezing device 4 moves downward, the squeezer 8 moves toward the direction of entering the squeezing port 10, and the depth of interference between the squeezer 8 and the wipe 3 is greater to clean and squeeze the wipe 3; Fig. 9 , the water squeezing device 4 moves upward, the squeezer 8 moves in the direction away from the squeezing port 10, the interference depth between the squeezer 8 and the wiping object 3 becomes smaller, and the mop head 2 and the wiping object 3 pass through the squeezing port 10 more effortlessly.

[0083] In other embodiments, it can also be arranged that the squeezer 8 is fixed to the water squeezing frame 6 or the active state of the squeezer 8 is opposite to the above-mentioned manner, when the water squeezing device 4 moves upward, the squeezer 8 cleans and squeezes water from the wipe 3, and the water squeezed out of the wipe 3 flows outward through the reflux hole 23, so that the reflux hole 23 has the dual functions of draining water outward and draining liquid inward under different usage conditions. Example 2

[0084] The difference between this embodiment and the first embodiment is that the liquid spraying mechanism 7 adopts the liquid pump discharge method.

[0085] In this embodiment, Figure 7 The liquid spraying mechanism 7 includes a pressing portion 12, a shell 18, a liquid spraying port 14 and a liquid pump 27. A cavity and a space for installing the pressing portion 12 are provided in the shell 18. The cavity forms a liquid storage chamber 13. The liquid pump 27 is installed between the pressing portion 12 and the liquid storage chamber 13, or installed in the liquid storage chamber 13. A liquid spraying port 14 is provided at the bottom of the shell 18 or on a side close to the wipe 3. When in use, the pressing portion 12 drives the liquid pump 27 to spray the cleaning liquid in the liquid storage chamber 13 from the liquid spraying port 14.

[0086] Preferably, such as 7 and Fig.13 The structure of the first liquid pump 27 is that the liquid pump 27 includes a pump housing 28, a pump core 29, a liquid inlet pipeline 30, a liquid inlet valve 31, a liquid outlet pipeline 32 and a liquid outlet valve 33. A cavity is provided in the pump housing 28, and a pump core 29 is movably installed in the cavity. A sealing ring 34 and a spring 35 are provided between the pump core 29 and the pump housing 28. The outer end of the pump core 29 extends from the pump housing 28 to form a pressing portion 12 or cooperates with the pressing portion 12. The cavity is also provided with a There are a liquid inlet 36 and a liquid outlet 37. The liquid inlet 36 is connected to the liquid inlet pipeline 30 through the liquid inlet valve 31, and the liquid outlet 37 is connected to the liquid outlet pipeline 32 through the liquid outlet valve 33. The end of the liquid inlet pipeline 30 is located in the liquid storage chamber 13, and the end of the liquid outlet pipeline 32 is connected to the liquid spray port 14. The liquid storage chamber 13 is also provided with a liquid filling port 38 for replenishing cleaning liquid into the liquid storage chamber 13, and a removable sealing plug 39 is provided on the liquid filling port 38.

[0087] The liquid pump 27 is used in the following manner: the pump core 29 moves into the pump housing 28 to squeeze out the air in the pump core 29, the liquid inlet valve 31 is closed, the liquid outlet valve 33 is opened, and the air in the pump housing 28 leaves from the liquid outlet pipeline 32; the spring 35 drives the pump core 29 to return outward, the volume between the pump core 29 and the pump housing 28 increases, the pressure decreases, the liquid outlet valve 33 is closed, the liquid inlet valve 31 is opened, the pressure difference between the liquid outlet valve 33 and the liquid storage chamber 13 causes the cleaning liquid in the liquid outlet chamber to enter the liquid outlet valve 33 through the liquid inlet pipeline 30 and the liquid inlet valve 31, and the liquid inlet valve 31 completes the pumping; the pump core 29 moves into the pump housing 28 again to change the hydraulic pressure in the liquid pump 27, the pressure difference between the liquid pump 27 and the outside world causes the liquid inlet valve 31 to close, the liquid outlet valve 33 to open, and the cleaning liquid in the pump housing 28 is sprayed out from the liquid outlet pipeline 32 and the liquid spray port 14.

[0088] In this embodiment, the shell 18 includes a front shell 40 and a rear shell 41, which together form a liquid storage chamber 13. A partition 42 is integrally formed on the rear shell 41, and the partition 42 separates the rear shell 41 into an upper and lower part. The lower part of the rear shell 41 forms the liquid storage chamber 13, and the upper part of the rear shell 41 forms an area for installing the pressing part 12. The middle part of the partition 42 extends into the liquid storage chamber 13 to form a pump shell 28 integrally formed with the rear shell 41. The liquid inlet 36, the liquid outlet 37 and the hole for installing the pump core 29 on the pump shell 28 connect the upper and lower parts of the rear shell 41.

[0089] In this embodiment, both the liquid inlet valve 31 and the liquid outlet valve 33 are duckbill valves, and the mouths of the two duckbill valves face in opposite directions.

[0090] Preferably, Fig.14 A reinforcing ring 44 is provided at the inner position of the periphery of the front shell 40. When the front shell 40 and the rear shell 41 are installed, the reinforcing ring 44 is inserted into the rear shell 41 and matches the surface of the rear shell 41. After the installation, there are two sets of substantially vertical fitting surfaces 45 between the front and rear shells 41. The two sets of fitting surfaces 45 work together to prevent the cleaning liquid in the liquid storage chamber 13 from leaking out. In order to further prevent leakage, glue or sealing accessories can be provided between the fitting surfaces 45, or the connection between the front and rear shells 41 can be processed by welding.

[0091] In other embodiments, the structures of the front shell 40 and the rear shell 41 may be interchanged, such as the partition 42 and the pump housing 28 are integrally formed on the front shell 40 , and the rear shell 41 is provided with a reinforcement ring 44 , which is inserted into the front shell 40 and adapted to the surface of the front shell 40 .

[0092] Preferably, the structure of the second liquid pump 27 is that the liquid pump 27 includes a pump housing 28, a pump core 29, a sealing member 46, a movable member 47, a liquid inlet valve 31 and a spring 35. The two opposite ends of the pump housing 28 are connected, respectively for liquid inlet and liquid outlet. A constriction section 48 is provided on the liquid inlet 36. The aperture of the constriction section 48 is smaller than that of other positions of the pump housing 28. The liquid inlet valve 31 is installed downstream of the constriction section 48. A sealing member 46 is fixedly installed at one end of the liquid outlet 37. A first connecting member 46 is provided at the center of the sealing member 46. The first connecting hole 49 is provided with a first interlayer 50 and a second interlayer 51 on the outer side of the first connecting hole 49, the pump core 29 and the movable part 47 are respectively installed at the upstream and downstream positions of the first connecting hole 49, the movable part 47 is provided with a penetrating second connecting hole 52, the pump core 29 is provided with a penetrating third connecting hole 53, the downstream of the pump core 29 is inserted into the second connecting hole 52 for installation, so that the second connecting hole 52 and the third connecting hole 53 are connected, and the downstream of the second connecting hole 52 is connected with the liquid injection port 14 through the liquid outlet pipeline 32.

[0093] The operating principle of this liquid pump 27 is: In the liquid spraying state, the movable member 47 is pressed to drive the pump core 29 to move upstream, and the third connecting hole 53 is separated from the blockage of the sealing member 46 to connect the second connecting hole 52 and the cavity in the pump housing 28. The movable member 47 and the pump core 29 continue to move upstream until the sealing member 46 is driven to move synchronously to squeeze the cavity volume of the pump housing 28. During the process of reducing the cavity volume of the pump housing 28, the liquid inlet pump blocks the liquid inlet port 36, and the cleaning liquid in the pump housing 28 cannot flow back to the liquid storage chamber 13, and can only flow out through the second connecting hole 52, the third connecting hole 53, the liquid outlet pipeline 32 and the liquid spraying port 14; In the liquid filling state, the elastic force of the spring 35 is released to cause the pump core 29 and the movable part 47 to move downstream synchronously, so that the third connecting hole 53 is blocked by the sealing part 46, and the second connecting hole 52 and the cavity in the pump housing 28 are blocked. The pump core 29 and the movable part 47 continue to move downstream until they drive the sealing part 46 to move synchronously to increase the cavity volume of the pump housing 28. During the process of increasing the cavity volume of the pump housing 28, the hydraulic pressure or air pressure on the upstream and downstream sides of the liquid inlet valve 31 is different. The cleaning liquid in the liquid storage chamber 13 pushes the liquid inlet pump to move downstream and open the liquid inlet port 36. The cleaning liquid is replenished into the cavity of the pump housing 28. After the pump core 29, the sealing part 46 and the movable part 47 move to the initial position, the liquid filling of the pump housing 28 is completed.

[0094] Preferably, the seal 46 is provided with a thin wall 54 on the outside of the first interlayer 50 and the second interlayer 51, and the thin wall 54 is in a bell-mouth shape. When the seal 46 moves in different directions, the hydraulic pressure or air pressure in the cavity of the pump casing 28 causes the thin wall 54 at different positions to deform and fit the inner wall of the pump casing 28 to avoid air or liquid leakage of the pump casing 28.

[0095] The upstream and downstream in this embodiment refer to the relative positions of the flow direction of the liquid in the liquid storage chamber 13 flowing to the liquid spray port 14 through the liquid pump 27, and have nothing to do with the installation direction of the liquid spray mechanism 7 and the installation direction of the liquid pump 27. That is, no matter in which direction the liquid spray mechanism 7 and the liquid pump 27 are located, the direction in which the cleaning liquid in the liquid storage chamber 13 flows out is fixed. The flow direction of the cleaning liquid in this embodiment is the liquid storage chamber 13, the liquid inlet pipeline 30, the pump housing 28, the liquid outlet pipeline 32 and the liquid spray port 14 in sequence.

[0096] Preferably, the structure of the third liquid pump 27 is that the liquid pump 27 is configured as an electric pump, which is installed in the liquid storage chamber 13 or outside the liquid storage chamber 13, and is connected to the liquid spray port 14 to drive the cleaning liquid in the liquid storage chamber 13 to the liquid spray port 14 for spraying. Example 3

[0097] The difference between this embodiment and the second embodiment is that the liquid injection mechanism 7 does not have a separate liquid pump 27 .

[0098] The first liquid discharge method in this embodiment is as follows: Fig.18The liquid spraying mechanism 7 includes a pressing portion 12, a shell 18 and a liquid spraying port 14. The cavity in the shell 18 forms a liquid storage chamber 13. The liquid spraying port 14 is located at the bottom of the shell 18. The top of the shell 18 is open. The pressing portion 12 is configured as a push rod, and the lower end is inserted into the liquid storage chamber 13. The pressing portion 12 moves downward in the liquid storage chamber 13 to squeeze the cleaning liquid out of the liquid storage chamber 13.

[0099] The second liquid discharge mode in this embodiment is that the liquid spraying mechanism 7 includes a pressing portion 12 , a shell 18 , a liquid spraying port 14 and a liquid spraying valve 55 . Specifically, the cavity in the shell 18 forms a liquid storage chamber 13, and the spray port 14 is arranged at a low position of the liquid storage chamber 13. The sealing plug 39 is detachably connected to the liquid filling port 38 of the shell 18. After the installation of the spray mechanism 7 is completed, the shell 41 body 18 forms a seal, that is, the shell 18 is rotated to any angle and the spray valve 55 can prevent the cleaning liquid from flowing out. The pressing part 12 is made of flexible material. By pressing the pressing part 12, it is deformed into the liquid storage chamber 13, the volume of the liquid storage chamber 13 is reduced, and an air pressure difference is formed between the liquid storage chamber 13 and the outside. The spray valve 55 is opened by the air pressure difference and sprays liquid outward; the pressing part 12 is released, and the pressing part 12 is deformed and reset to its original shape. After the liquid is sprayed, the internal air pressure of the liquid storage chamber 13 is lower than the external air pressure. The internal and external air pressure difference causes the spray valve 55 to open and replenish air into the liquid storage chamber 13 until the internal and external air pressures of the liquid storage chamber 13 are balanced.

[0100] Preferably, Fig.19 The liquid spraying mechanism 7 can be configured such that the housing 18 is made of hard plastic, the pressing portion 12 is made of flexible material, and the housing 18 and the pressing portion 12 are connected in a sealed manner; Fig. 20 The liquid spraying mechanism 7 can also be configured such that the housing 18 is made of a flexible material as a whole, and the surface of the housing 18 can be pressed to form a pressing portion 12 at a position where the deformation is generated, so as to realize the liquid spraying by changing the air pressure; Fig.21 The liquid spraying mechanism 7 can also be a structure in which the entire shell 18 is set to be retractable and foldable. The surface of the shell 18 can be pressed to form a pressing portion 12 at a position where the retractable and foldable portion is pressed, thereby realizing the liquid spraying by changing the air pressure.

[0101] Further, such as Fig. 22 The shell 18 is made of hard plastic, the pressing part 12 is made of flexible material or is set to a retractable and foldable structure, the pressing part 12 is connected to the shell 18 through an air pipe 56, the pressing part 12 is squeezed outside the shell 18, and the air in the pressing part 12 enters the liquid storage chamber 13 through the air pipe 56 to squeeze the cleaning liquid out of the liquid spray port 14. Example 4

[0102] The difference between this embodiment and the third embodiment lies in the structure of the mounting platform 19 .

[0103] In this embodiment, the mounting platform 19 refers to a device for fixing the flat-plate mop and the spray mechanism 7 as a whole. The mounting platform 19 can be set on the flat-plate mop, or on the spray mechanism 7, or on the flat-plate mop and the spray mechanism 7 respectively. After the flat-plate mop and the spray mechanism 7 are installed, the devices for fixing are combined to form the mounting platform 19.

[0104] In this embodiment, the flat mop and the spray mechanism 7 are two independent entities during production and processing. The components of the spray mechanism 7 are formed and installed into an integral and complete spray module and then installed with the flat mop to improve the efficiency of production, installation and inspection of the spray mechanism 7, and reduce the cost of replacement and scrapping of the spray mechanism 7 and the flat mop that fail the water test.

[0105] The installation platform 19 in this embodiment can be implemented in a variety of structures, and in some structures, the installation platform 19 makes it unnecessary for the spray mechanism 7 to be used with a specially made flat mop. The installation platform 19 makes the spray mechanism 7 adaptable to flat mops that are sold in the market and purchased by users, making the application range of the spray mechanism 7 wider.

[0106] Preferably, the first mounting platform 19 is configured as follows: Figure 23-24 The upper part of the water squeezing jacket 5 is provided with a heightened enclosure 57 protruding outward, the outer end of the enclosure 57 is flush, the inner side wall of the enclosure 57 is provided with an L-shaped first protrusion 58, and the arms extending in two directions of the first protrusion 58 form a slot 59. An extension platform 60 is provided on the shell 18 of the spray mechanism 7, and a second protrusion 61 is provided on the side of the extension platform 60. During installation, the first protrusion 58 and the second protrusion 61 are misaligned, and the extension platform 60 is inserted into the enclosure 57, and the spray mechanism 7 is rotated in a preset direction so that the second protrusion 61 enters the slot 59 formed by the first protrusion 58, thereby realizing the rapid installation and disassembly of the spray mechanism 7. In this way, the enclosure 57 and the extension platform 60 jointly form the installation platform 19.

[0107] More specifically, the frame 57 is arranged in a square shape, and two opposite inner side walls of the frame 57 are provided with a first protrusion 58, and the two first protrusions 58 are centrally symmetrical. The extension platform 60 is arranged in a circular shape and the diameter of the extension platform 60 is smaller than the length of the smallest side of the frame 57. During installation, the second protrusion 61 is aligned with the corner position of the frame 57 and the extension platform 60 is inserted into the frame 57 until the extension platform 60 and the frame 57 are butted against each other. At this time, the spray mechanism 7 can be rotated to insert the second protrusion 61 into the slot 59 for positioning. The square setting of the frame 57 makes the corner area of ​​the frame 57 give way for the insertion of the second protrusion 61 to form an installation positioning point, that is, other positions except the corners will butt against the second protrusion 61 to prevent the second protrusion 61 from being inserted into the frame 57, thereby simplifying the positioning of the spray mechanism 7 during installation. In addition, to prevent the second protrusion 61 from being inserted into the corner away from the slot 59, in this embodiment, an anti-mistake position 62 is also provided at the corner away from the slot 59. The anti-mistake position 62 is achieved by setting a shape different from the other corner, setting a mark, or setting a stop block.

[0108] Of course, in other embodiments, such as Fig.25 Alternatively, an L-shaped slot 59 may be provided in one of the surrounding frame 57 and the extension platform 60 , and a second protrusion 61 may be provided on the other, and the installation positioning may be achieved by aligning the second protrusion 61 with the outer end of the slot 59 .

[0109] Preferably, the second mounting platform 19 is configured as follows: Fig.26 A frame 57 is provided on the upper part of the water squeezing jacket 5, and an inner wall of the frame 57 is provided with an internal thread 63. An extension platform 60 is provided on the shell 18, and an external thread 64 is provided on the side of the extension platform 60. The frame 57 and the extension platform 60 together form an installation platform 19. During installation, the spray mechanism 7 is rotated to make it threadedly connected with the extension platform 60.

[0110] Preferably, the third mounting platform 19 is configured as follows: Fig. 27 A frame 57 is provided on the upper part of the water squeezing jacket 5, a male buckle 65 is provided on the inner wall of the frame 57, an extension platform 60 is provided on the shell 18, and a female buckle 66 is provided on the side of the extension platform 60. The frame 57 and the extension platform 60 together form an installation platform 19. During installation, the liquid spraying mechanism 7 is pressed to make it snap-connected with the extension platform 60.

[0111] Preferably, the fourth installation platform 19 is configured such that an extension platform 60 is provided on one or both of the water squeezing jacket 5 and the shell 18 , and the water squeezing jacket 5 and the liquid spraying mechanism 7 are fixedly connected by installing screws on the extension platform 60 .

[0112] In the above embodiments, the four types of mounting platforms 19 are all configured as detachable structures, so that the liquid spraying mechanism 7 can be fixedly mounted with the flat mop for use in combination to spray liquid on the wiping material 3, or the flat mop and the liquid spraying mechanism 7 can be used alone after the liquid spraying mechanism 7 is detached. At the same time, the elevated or extended portion provided on the mounting platform 19 allows the liquid spraying mechanism 7 to be suspended outside the water squeezing jacket 5, and the upper ends of the mop head 2 and the wiping material 3 can be inserted into the gap between the liquid spraying mechanism 7 and the water squeezing jacket 5 for positioning or liquid spraying.

[0113] In other embodiments, on the basis of using the surrounding frame 57 and the extension platform 60, the water squeezing jacket 5 and the liquid spraying mechanism 7 can be connected to form a non-detachable structure by riveting, welding or the like.

[0114] The various structures of the mounting platforms 19 mentioned above all require a special squeezing sleeve 5 to install the spray mechanism 7. In order to facilitate the use of the spray mechanism 7 with an ordinary squeezing sleeve 5 and an ordinary mop, the mounting platform 19 can also be set as a whole on the spray mechanism 7 in this embodiment.

[0115] Specifically, Fig.28 The housing 18 of the liquid spraying mechanism 7 is provided with an extension platform 60, and a clamping structure such as a clamp, a clamp ring 67, a strap, a pipe clamp, a cable tie, a magic band, etc. is provided on the extension platform 60. The clamping structure fixes the liquid spraying mechanism 7 on the ordinary mop or the squeezing jacket 5 by embracing the mop rod 1 or the squeezing jacket 5. The liquid spraying mechanism 7 is fixedly installed on the mop or the squeezing jacket 5 of different sizes by adjusting the elasticity and tightness of the clamping structure. The extension platform 60 and the clamping structure together form a mounting platform 19. The clamping structure is used to mount the liquid spraying mechanism 7 on the mop. The extension platform 60 is used to control the distance between the liquid spraying mechanism 7 and the mop rod 1 and the squeezing jacket 5 to avoid the protruding parts on the mop affecting the installation of the liquid spraying mechanism 7. It can also facilitate the mop head 2 and the wiping material 3 to enter the gap between the liquid spraying mechanism 7 and the mop rod 1 or the squeezing jacket 5 to position the liquid spray. Even if the installed mop is not provided with the squeezing device 4, the installed liquid spraying mechanism 7 can be used to spray liquid on the wiping material 3, and then the wiping material 3 is placed on other cleaning devices such as a mop bucket for cleaning, thereby expanding the range of mops that can be used with the liquid spraying mechanism 7.

[0116] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
