[0055] As Figures 1-28 A flat mop includes a mop rod 1 and a mop head 2 connected by rotation, the mop head 2 is provided with a wiping material 3, the mop rod 1 is provided with a squeezing device 4 which can move up and down, the squeezing device 4 includes a squeezing sleeve 5, a squeezing frame 6 and a liquid spraying mechanism 7, the squeezing frame 6 is provided with a squeezer 8 for cleaning the wiping material 3, the mop head 2 is rotated to a direction substantially parallel to the mop rod 1, the 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 to the wiping material 3, and the squeezer 8 moves to clean the wiping material 3 along with the squeezing device 4.

[0056] The connection structure of the mop rod 1 and the mop head 2 in the present application adopts the common connection structure in the prior art, and 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, and the steering mechanism can also keep the mop head and the mop rod in a vertical or parallel position. The connection structure of the mop rod and the mop head is not described again in the present application.

[0057] It should be noted that the cleaning liquid sprayed by the liquid spraying mechanism 7 in the utility model is a general term, not specifically referring to ordinary cleaning liquid, which can be a cleaning liquid such as dishwashing liquid, hand sanitizer, laundry detergent, etc. for directly cleaning articles or cooperating with water for cleaning articles, or a liquid such as alcohol or disinfectant for sterilization and disinfection, or a liquid for removing odor and increasing fragrance, and of course, it can also be ordinary water. Spraying water can increase the moisture of the wiping article 3 or the ground. It can be understood that the above-mentioned liquids can be sprayed on the wiping article 3 or the ground to improve the cleaning effect of the wiping article 3 or the ground.

[0058] The water squeezing device 4 in the utility model comprises a water squeezing sleeve 5, a water squeezing frame 6 and a liquid spraying mechanism 7, specifically, Figure 2 The top of the water squeezing sleeve 5 is provided with a sleeve, which can be sleeved 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 with the water squeezing frame 6. The lower end of the water squeezing sleeve 5 can also be a sleeve sleeved on the outer surface of the mop rod 1. As Figure 3 It can also be a connecting rod 9 extending up and down on the outer side of the mop rod 1. As Figure 4 The water squeezing frame 6 is provided with a squeezing opening 10 and a rod opening 11 penetrating up and down. The squeezing opening 10 and the rod opening 11 are transversely communicated. The squeezing opening 10 is used for the mop head 2 and the wiping article 3 to pass through up and down during cleaning. The rod opening 11 is sleeved on the outer surface of the mop rod 1. During the process of the mop head 2 and the wiping article 3 entering the squeezing opening 10, the front and rear sides of the water squeezing frame 6 can simultaneously support the mop rod 1, the mop head 2 and the wiping article 3. The upper end of the water squeezing frame 6 is fixedly connected with the lower end of the water squeezing sleeve 5 to form a whole water squeezing device 4.

[0059] In the utility model, the liquid spraying mechanism 7 comprises a pressing part 12, a liquid storage cavity 13 and a liquid spraying opening 14. The liquid storage cavity 13 is used for storing cleaning liquid. The pressing part 12 is used for controlling the cleaning liquid to be sprayed out of the liquid spraying opening 14 and sprayed on the wiping article 3 or the ground. The upper end of the water squeezing sleeve 5 forms a water squeezing handle 15 for the hand of a 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 located below the water squeezing handle 15 to provide a space for the hand of the user to hold, so that when the flat mop is used to clean the wiping article 3, one hand is held on the upper end of the mop rod 1 and the other hand is held on the water squeezing handle 15 to push and pull the water squeezing handle 15 up and down to realize the relative movement between the water squeezing device 4 and the wiping article 3 for cleaning. The position of the liquid spraying mechanism 7 is arranged to facilitate the user to hold the water squeezing handle 15 to push and pull the water squeezing device 4 to clean the wiping article 3, which can simultaneously control the liquid spraying mechanism 7 to spray cleaning liquid on the wiping article 3 to further clean or moisten the wiping article 3, so as to realize the one-handed operation to spray liquid on the wiping article 3 and clean the wiping article 3 at the same time.

[0060] When different cleaning liquids are selected, the corresponding liquid spraying port 14 can also be replaced accordingly. For example, when the liquid of the cleaning liquid such as dishwashing liquid is relatively thick, the liquid spraying port 14 needs a large diameter, and the thick cleaning liquid is sprayed on the wiping material 3 in a point or line manner. Then, the wiping material 3 is moved and contacted by the squeezer 8 on the surface of the wiping material 3 to mix the cleaning liquid on the point or line on the surface of the wiping material 3 with the cleaning water or the water on the wiping material 3, and then the mixture is driven to the area that is not sprayed with the cleaning liquid, so that the whole or most of the wiping material 3 can be cleaned by the cleaning liquid. When the liquid quality of the cleaning liquid such as alcohol is relatively thin, the liquid spraying port 14 with a large diameter and spraying in a point or line manner can be selected, or the liquid spraying port 14 with a small diameter and spraying in a surface manner can be selected, or the liquid spraying port 14 with adjustable liquid spraying manner can be selected to adjust the liquid spraying manner to point, line or surface according to the use requirement. Similarly, the squeezer 8 is moved and contacted on the surface of the wiping material 3 to drive the cleaning liquid to the area that is not sprayed with the cleaning liquid, so as to improve the cleaning effect or disinfection and deodorization effect of the wiping material 3.

[0061] Specific use mode is, for example Figure 5 , the water squeezing device 4 is positioned at the high position of the mop rod 1, the mop head 2 is rotated to the position perpendicular to or inclined to the mop rod 1, at this time, the flat mop can be used for cleaning the ground; the mop head 2 is rotated to the position substantially parallel to the mop rod 1, the water squeezing device 4 is pushed downward, the mop head 2 and the wiping material 3 enter the squeezing port 10 upward, the squeezer 8 cleans the wiping material 3, and the pressing part 12 sprays the cleaning liquid to the wiping material 3 to improve the cleaning effect.

[0062] In the utility model, taking the normal use or upright placement of the flat mop as an example, the direction of the mop head 2 close to the ground is the downward direction, the top direction of the mop rod 1 is the upward direction, the mop head 2 is rotated to the position parallel to the mop rod 1, the direction faced by the wiping material 3 is the front direction, the direction away from the wiping material 3 is the rear direction, the left and right directions are the other two directions of the horizontal plane relative to the front and rear directions, the squeezer 8 and the liquid spraying port 14 are located in the front of the water squeezing device 4, preferably, when the wiping material 3 is parallel to the mop rod 1, the squeezer 8 and the liquid spraying port 14 are located in the front of the wiping material 3, so that the squeezer 8 can contact and clean the wiping material 3 and squeeze water, and the moving resistance between the squeezer 8 and the wiping material 3 will not be too large, and the squeezer 8 and the wiping material 3 can also provide space for the liquid spraying port 14 to spray liquid to the wiping material 3.

Since liquid spraying inspection is required for each liquid spraying mechanism 7 during production and installation or inspection, the liquid spraying mechanism 7 that passes the inspection can be installed on the installation platform 19, while the liquid spraying mechanism 7 that fails the inspection needs to be repaired or destroyed. The complete liquid spraying module is provided, and the liquid spraying module can be individually subjected to liquid spraying inspection. In the prior art, the liquid spraying mechanism is associated with the wringing device, that is, part of the components in the wringing device form part of the components in the liquid spraying mechanism, such as the cavity provided in the wringing sleeve to form the liquid storage cavity of the liquid spraying mechanism. Alternatively, during production and installation, the components of the liquid spraying mechanism need to be respectively installed at different positions of the wringing device, such as the pressing part being installed on the wringing handle, the liquid spraying port being installed on the wringing frame, and the liquid storage cavity being provided on the wringing sleeve or the wringing frame, and the control accessories or waterway are connected to the pressing part, the liquid storage cavity, and the liquid spraying port. The above-described installation structure of the liquid spraying mechanism requires the complete wringing device or even the complete flat mop to be subjected to liquid spraying inspection during production and inspection. Since the components to be inspected are large, the inspection is troublesome and inefficient. If a product with abnormal liquid spraying is found, the wringing device and the liquid spraying mechanism need to be repaired or destroyed as a whole, which increases the difficulty of maintenance and the cost of scrapping. If liquid spraying inspection is not performed, unqualified products may flow into the market, resulting in negative situations. Compared with the liquid spraying mechanism in the prior art, the assembly, inspection, and repair of the liquid spraying mechanism 7 and the wringing device 4 in the embodiment are simpler and have lower costs.

[0066] In the embodiment, the liquid spraying mechanism 7 and the wringing frame 6 are independent, which includes functional independence and structural independence. The functional independence means that the liquid spraying function of the liquid spraying mechanism 7 and the cleaning and wringing function of the wringing frame 6 are independent. Whether the liquid spraying mechanism 7 and the wringing device 4 are installed as a whole or not, the liquid spraying function of the liquid spraying mechanism 7 and the wringing function of the wringing frame 6 can be realized independently. Figure 2 Figure 5 The structural independence means that the liquid spraying mechanism 7 is independent of the wringing frame 6 in structure, that is, the liquid spraying mechanism 7 is independent of the wringing frame 6 in function and structure. The liquid spraying mechanism 7 is integrally installed on the wringing sleeve 5. When the liquid spraying mechanism 7 is installed on the wringing sleeve 5, the flat mop has both the liquid spraying function and the cleaning and wringing function of the wiping material 3. When the liquid spraying mechanism 7 is detached, the flat mop still has the cleaning and wringing function of the wiping material 3. The detached liquid spraying mechanism 7 can still be used as a liquid spraying bottle to spray liquid on other objects.

[0067] The structural independence means that the liquid spraying mechanism 7 is independent of the wringing frame 6 in structure, that is, the liquid spraying mechanism 7 is independent of the wringing frame 6 in function and structure. The liquid spraying mechanism 7 is integrally installed on the wringing sleeve 5. When the liquid spraying mechanism 7 is installed on the wringing sleeve 5, the flat mop has both the liquid spraying function and the cleaning and wringing function of the wiping material 3. When the liquid spraying mechanism 7 is detached, the flat mop still has the cleaning and wringing function of the wiping material 3. The detached liquid spraying mechanism 7 can still be used as a liquid spraying bottle to spray liquid on other objects. Figure 5 The structural independence means that the liquid spraying mechanism 7 is independent of the wringing frame 6 in structure, that is, the liquid spraying mechanism 7 is independent of the wringing frame 6 in function and structure. The liquid spraying mechanism 7 is integrally installed on the wringing sleeve 5. When the liquid spraying mechanism 7 is installed on the wringing sleeve 5, the flat mop has both the liquid spraying function and the cleaning and wringing function of the wiping material 3. When the liquid spraying mechanism 7 is detached, the flat mop still has the cleaning and wringing function of the wiping material 3. The detached liquid spraying mechanism 7 can still be used as a liquid spraying bottle to spray liquid on other objects.​

[0068] In the above embodiments, as Figure 5 , the housing 18 extends towards the wringing frame 6, the liquid spraying port 14 is arranged at the end of the housing extension section, and the housing extension section forms the liquid storage cavity 13, that is, the spraying direction of the liquid spraying port 14 is substantially parallel to the extension direction of the mop rod 1, when the wringing device 4 moves downward along the mop rod 1, the mop head 2 and the wiping material 3 move upward relatively, the wiping material 3 passes through the pressing opening 10 upward into the spraying area 20, until the bottom of the liquid spraying mechanism 7 moves to a height close to or at least partially coincides with the top of the wiping material 3, during the process of the wiping material 3 entering and leaving the spraying area 20, or when the wiping material 3 moves to the preset highest position, the pressing part 12 controls the liquid spraying port 14 to spray cleaning liquid to the spraying area 20 for self-cleaning of the wiping material 3.

[0069] Since the liquid spraying port 14 in the embodiment is arranged exposedly and does not fit with the wiping material 3, when the liquid spraying function is used, the flat mop needs to be controlled in a direction with the wiping material 3 horizontally upward or obliquely upward, and the cleaning liquid can fall on the wiping material 3 under the action of the spraying force and gravity, avoiding the cleaning liquid from falling on the ground. Of course, in the case of not considering the cleaning liquid falling on the ground, the liquid spraying function can also be used in the direction of the flat mop being placed vertically. Since the general flat mop generally aims the wiping material 3 upward to the faucet when cleaning the wiping material 3, under this cleaning habit, even if the liquid spraying port 14 does not contact the wiping material 3, the cleaning liquid can also be sprayed on the wiping material 3.

[0070] As Figure 6 , in order to avoid the user from accidentally touching the pressing part 12 or spraying liquid in the case of the wiping material 3 downward, so that the cleaning liquid cannot be sprayed on the wiping material 3, the liquid spraying port 14 can also be arranged obliquely, so that the cleaning liquid can still move on the wiping material 3 according to its inertia after leaving the liquid spraying port 14, so that the cleaning liquid can be sprayed on the wiping material 3 regardless of the angle of the flat mop.

[0071] Compared with the liquid spraying port 14 arranged to fit or contact the wiping material 3 for spraying liquid, the cleaning liquid in the embodiment first passes through the external air after leaving the liquid spraying port 14, and then falls on the wiping material 3, whether the liquid spraying mechanism 7 sprays liquid and the size of the spraying amount can be observed through the movement of the cleaning liquid in the external air and the situation of falling on the wiping material 3, so as to adjust the spraying size of the liquid spraying mechanism 7 and supplement the cleaning liquid in the liquid storage cavity 13 by the user. At the same time, the way of the liquid spraying port 14 contacting the wiping material 3 for spraying liquid, the dust and dirt on the wiping material 3 are easy to block the liquid spraying port 14, affecting the spraying effect.

[0072] In order to illustrate the independent situation of the liquid spraying mechanism 7 and the wringing frame 6 and the position of the spraying area 20, as Figure 5 and Figure 8, the length of the wringing device 4 is X, the length of the mop head 2 or the wiping material 3 is Y, the length of the distance between the liquid spraying port 14 and the wringing frame 6 is Z, and the space where the length Z is located is the spraying area 20, which is used for the movement of the spraying process of the cleaning liquid and for the user to observe the spraying state. The length X is greater than the length Y, so as to avoid the contact between the hand and the wiping material 3 during the movement of the wringing device 4. In order to avoid the sprayed cleaning liquid from falling on the wringing frame 6 or even falling on the ground beyond the wringing frame 6, the length Z in the embodiment is set to be greater than one half of the length Y. The lengths X, Y and Z in the embodiment are all the horizontal lengths in the state of the flat plate mop as shown in the drawing. Figure 8 It should be noted that if the lengths of the wringing device 4, the mop head 2 and the wiping material 3 can be adjusted or folded, only the lengths of the wringing device 4, the mop head 2 and the wiping material 3 in the normal cleaning and wringing state are compared. The length Z generally refers to the distance between the top of the wringing frame 6 (excluding the wringing sleeve 5) and the part of the liquid spraying mechanism 7 closest to the wringing frame 6. For example, if most of the parts of the wringing device 4 are located above the wringing sleeve 5, and the liquid spraying port 14 is arranged in the wringing frame 6, then the length Z is zero or even a negative length.

[0073] In the above embodiment, when the wringing device 4 moves to the lowest position relative to the mop head 2, that is, the mop head 2 and the wiping material 3 move upward to the highest position, the liquid spraying mechanism 7 and the wiping material 3 have an overlapping area along the plane perpendicular to the mop rod 1, or they are always not overlapping, as shown in Figure 5 and Figure 8 , which are schematic diagrams of the ways in which the liquid spraying mechanism 7 and the wiping material 3 have an overlapping area and are always not overlapping, respectively.

[0074] In other embodiments, the liquid spraying port 14 can also be arranged at a position close to the wiping material 3 on the shell 18, and the liquid spraying port 14 sprays liquid onto the wiping material 3 when the liquid spraying port 14 moves to overlap with the wiping material 3 at any position. In this spraying mode, a space for the mop head 2 and the wiping material 3 to enter is arranged between the wringing sleeve 5 and the liquid spraying mechanism 7, and the space forms the spraying area 20. 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 overlaps 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 wiping material 3 that can be sprayed is related to the overlapping length of the movement of the wiping material 3 and the liquid spraying port 14 and the width of the liquid spraying port 14. If there is an area that is not sprayed with cleaning liquid, the squeezer 8 moves relative to the wiping material 3 to evenly spread the cleaning liquid and bring the cleaning liquid to the area that is not sprayed, so as to realize that the wiping material 3 as a whole receives the cleaning liquid.

[0075] Compared with the existing liquid spraying mechanism, the liquid spraying mechanism 7 in the embodiment is more integrated and simple. The water jacket 5 and the water squeezing frame 6 do not need to be provided with a separate cavity for installing a water channel, thereby simplifying the installation structure of the water squeezing device 4 and the liquid spraying mechanism 7, improving the production assembly efficiency. Meanwhile, the water channel of the liquid spraying mechanism 7 is independent of the water jacket 5 and the water squeezing frame 6, which can avoid the water channel in the water jacket 5 and the water squeezing frame 6 being bent and blocked due to the pressure and tension caused by the up-and-down movement of the water squeezing device 4. Of course, the liquid spraying mechanism 7 in the embodiment is provided as an independent liquid spraying module, and the water channel can not be provided, and the cleaning liquid can be directly sprayed from the liquid storage cavity 13 to the spraying port 14.

[0076] In the above embodiment, the part of the water squeezing frame 6 located at the front side of the squeezing port 10 has a certain thickness, which can increase the strength of the water squeezing frame 6 as a whole, so as to avoid the deformation of the water squeezing frame 6 outward when the mop head 2 and the wiping material 3 enter the squeezing port 10. The space formed by the thickness of the front side of the water squeezing frame 6 can be used for installing the squeezer 8.

[0077] Preferably, the front side of the water squeezing frame 6 is provided with an intercepting portion 21 extending to the front side. When the spraying force of the liquid spraying mechanism 7 is large or the length Z of the liquid spraying mechanism 7 is small, the sprayed liquid is easy to fly away from the area where the wiping material 3 is located. The provision of the intercepting portion 21 can block the liquid about to leave the wiping material 3, so as to avoid the liquid moving to the ground, the wall surface or other positions where the liquid is not needed. In the embodiment, the intercepting portion 21 is perpendicular to the wiping material 3 during water squeezing or is inclinedly provided with the front end being high and the rear end being low. If the intercepting portion 21 is provided with the front end being low and the rear end being high, no matter whether the inclined surface is a straight surface or an arc surface, the cleaning liquid is easy to be guided outward along the extension direction of the intercepting portion 21. In the embodiment, the intercepting portion 21 can be provided in the following ways.

[0078] The first way is as shown in Figure 9 , the intercepting portion 21 is provided outside the front of the water squeezing frame 6, that is, a raised portion is provided in front of the water squeezing frame 6. The surface angle area between the intercepting portion 21 and the water squeezing frame 6 forms a temporary storage area 22. The intercepting portion 21 can also be provided in a perpendicular or inclined way to the wiping material 3. In order to prevent the liquid in the temporary storage area 22 from flowing outward and being used for cleaning the wiping material 3, any one or more of the three positions between the intercepting portion 21, the water squeezing frame 6 and the water squeezing frame 6 can be provided with a backflow hole 23. The liquid in the temporary storage area 22 can flow into the squeezing port 10 through the backflow hole 23 to clean the water squeezing frame 6, the squeezer 8 or the wiping material 3. The external cleaning water can also enter the water squeezing frame 6 through the backflow hole 23 to clean the water squeezing frame 6, the squeezer 8 or the wiping material 3.

[0079] The second way is as shown in Figure 10The intercepting part 21 is located at the top of the front side of the wringer 6, or the top surface of the front side of the wringer 6 forms the intercepting part 21. The intercepting part 21 blocks part of the liquid and forms a temporary storage area 22 above the intercepting part 21. When the intercepting part 21 is inclined, the angled area between the intercepting part 21 and the wiping material 3 forms the temporary storage area 22. This temporary storage area 22 can intercept and store more liquid. In general use, the inclined intercepting part 21 is more vertical, and its guiding effect is better. Similarly, the intercepting part 21 can also be provided with a through-hole 23. The liquid in the temporary storage area 22 can flow into the squeezing port 10 or the wringer 6 through the through-hole 23 to clean the wiping material 3. External cleaning water can also enter the wringer 6 through the through-hole 23 to clean the wringer 6, the squeezer 8, or the wiping material 3.

[0080] The third type, such as Figure 11 Furthermore, by setting up the two types of interception units 21 mentioned above, the interception effect is improved.

[0081] Preferably, the interception section 21 adopts a flat surface or a rear end that is lower than the front end to improve the interception and diversion effect.

[0082] In the above embodiment, when the flat mop is washing and wringing out water, as the wringing device 4 moves downward relative to the wiping object 3, the squeezer 8 squeezes the wiping object 3, and the water in the wiping object 3 is driven downward by the squeezer 8. The wringing frame 6 is provided with a drain hole 24 below the interception part 21. The drain hole 24 and the return hole 23 are independent. The water generated by the squeezer 8 in cleaning and wringing out the wiping object 3 flows outward through the drain hole 24 and the squeeze port 10.

[0083] Specifically, such as Figure 12 The squeezer 8 is equipped with an inclined rail 25. Both ends of the squeezer 8 are movably mounted on the inclined rail 25 via protrusions 26. During washing or wringing, the squeezer 8 moves under the pressure of the wiping material 3 to adjust the tightness between the squeezer 8 and the wiping material 3. Figure 10 The squeezing device 4 moves downward, and the squeezer 8 moves towards the squeezing port 10, increasing the depth of interference between the squeezer 8 and the wiping material 3 to clean and squeeze out water from the wiping material 3; Figure 9 The squeezing device 4 moves upward, and the squeezer 8 moves away from the squeezing port 10. The interference depth between the squeezer 8 and the wiping material 3 becomes smaller, and the mop head 2 and the wiping material 3 pass through the squeezing port 10 with less effort.

[0084] In other embodiments, the squeezer 8 may be fixed to the water squeezing frame 6 or the activity state of the squeezer 8 may be reversed as described above. When the water squeezing device 4 moves upward, the squeezer 8 cleans and squeezes water from the wiping material 3. The water squeezed out of the wiping material 3 flows out through the return hole 23, so that the return hole 23 has the dual function of draining water outward and draining liquid inward under different usage conditions. Example 2

[0085] The same as example 1, this example will not repeat the description of the same, only describe the different, this example and example 1 different in that: the liquid spraying mechanism 7 using pump out liquid way.

The use mode of the liquid pump 27 is that the pump core 29 moves into the pump shell 28 to extrude 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 shell 28 leaves from the liquid outlet pipeline 32; the spring 35 drives the pump core 29 to move outwardly to reset, the volume between the pump core 29 and the pump shell 28 becomes larger, the pressure becomes smaller, the liquid outlet valve 33 is closed, the liquid inlet valve 31 is opened, and the pressure difference between the liquid outlet valve 33 and the liquid storage cavity 13 makes the cleaning liquid in the liquid outlet cavity enter the liquid outlet valve 33 through the liquid inlet pipeline 30 and the liquid inlet valve 31 to complete the liquid suction of the liquid inlet valve 31; the pump core 29 moves into the pump shell 28 again to change the liquid pressure in the liquid pump 27, the pressure difference between the liquid pump 27 and the outside makes the liquid inlet valve 31 close and the liquid outlet valve 33 open, and the cleaning liquid in the pump shell 28 is sprayed from the liquid outlet pipeline 32 and the liquid spraying port 14.

[0088] In the embodiment, the shell 18 comprises a front shell 40 and a rear shell 41, the front shell 40 and the rear shell 41 enclosing the liquid storage cavity 13, the rear shell 41 integrally forming a partition plate 42, the partition plate 42 separating the rear shell 41 into upper and lower parts, the lower part of the rear shell 41 forming the liquid storage cavity 13, the upper part of the rear shell 41 forming an area for mounting the pressing part 12, the partition plate 42 extending into the liquid storage cavity 13 in the middle part 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 mounting the pump core 29 on the pump shell 28 allowing the upper and lower parts of the rear shell 41 to communicate.

[0089] In the embodiment, the liquid inlet valve 31 and the liquid outlet valve 33 are both duckbill valves, and the mouths of the two duckbill valves are oppositely directed.

[0090] Preferably, as Figure 14 , a reinforcing ring 44 is arranged at the inner position of the periphery of the front shell 40, the reinforcing ring 44 being inserted into the rear shell 41 and being adapted to the surface of the rear shell 41 during installation of the front shell 40 and the rear shell 41, the front shell 41 and the rear shell 41 being installed to have two sets of substantially vertical abutting surfaces 45, the two sets of abutting surfaces 45 jointly preventing the cleaning liquid in the liquid storage cavity 13 from leaking out. In order to further prevent leakage, glue, sealing accessories or welding of the connection between the front shell 41 and the rear shell 41 can be used.

[0091] In other embodiments, the structure of the front shell 40 and the rear shell 41 can also be exchanged, such as the partition plate 42 and the pump shell 28 being integrally formed on the front shell 40, the rear shell 41 being provided with the reinforcing ring 44, the reinforcing ring 44 being inserted into the front shell 40 and being adapted to the surface of the front shell 40.

[0092] Preferably, the second liquid pump 27 is structured as follows: the liquid pump 27 comprises a pump shell 28, a pump core 29, a sealing member 46, a movable member 47, an inlet valve 31 and a spring 35, the pump shell 28 is through at opposite ends for liquid inlet and outlet, the inlet port 36 is provided with a necked section 48, the aperture of the necked section 48 is smaller than other positions of the pump shell 28, the inlet valve 31 is installed downstream of the necked section 48, the outlet port 37 is fixedly installed with the sealing member 46 at one end, the sealing member 46 is provided with a first connecting hole 49 at the center position, the first connecting hole 49 is provided with a first interlayer 50 and a second interlayer 51 at the outer side, the pump core 29 and the movable member 47 are respectively installed at upstream and downstream positions of the first connecting hole 49, the movable member 47 is provided with a second connecting hole 52, the pump core 29 is provided with a third connecting hole 53, the pump core 29 is inserted into the second connecting hole 52 at the downstream position for installation, so that the second connecting hole 52 and the third connecting hole 53 are communicated, and the second connecting hole 52 is communicated with the liquid outlet pipeline 32 and the liquid injection port 14 at the downstream position.

[0093] The use principle of the liquid pump 27 is as follows:

[0094] In the initial state, the spring 35 pushes the third connecting hole 53 to be blocked by the sealing member 46 to block the clean liquid between the pump shell 28 and the liquid outlet pipeline 32, and the stepped portion of the movable member 47 is separated from the sealing member 46.

[0095] In the liquid injection state, the movable member 47 is pressed to drive the pump core 29 to move upstream, the third connecting hole 53 is separated from the blocking of the sealing member 46 to communicate the second connecting hole 52 and the cavity in the pump shell 28, the movable member 47 and the pump core 29 continue to move upstream until the sealing member 46 is synchronously moved to extrude the cavity volume of the pump shell 28, in the process of reducing the cavity volume of the pump shell 28, the inlet valve 31 blocks the inlet port 36, the clean liquid in the pump shell 28 cannot flow back to the liquid storage cavity 13, but can only flow out through the second connecting hole 52, the third connecting hole 53, the liquid outlet pipeline 32 and the liquid injection port 14.

[0096] In the liquid injection state, the spring 35 is released to drive the pump core 29 and the movable member 47 to move downstream synchronously, so that the third connecting hole 53 is blocked by the sealing member 46, the second connecting hole 52 and the cavity in the pump shell 28 are blocked, the pump core 29 and the movable member 47 continue to move downstream until the sealing member 46 is synchronously moved to increase the cavity volume of the pump shell 28, in the process of increasing the cavity volume of the pump shell 28, the liquid pressure or gas pressure on both sides of the inlet valve 31 is different, the clean liquid in the liquid storage cavity 13 pushes the inlet valve 31 to move downstream and open the inlet port 36, the clean liquid is supplemented into the cavity of the pump shell 28, and after the pump core 29, the sealing member 46 and the movable member 47 move to the initial position, the liquid inlet of the pump shell 28 is completed.

[0097] Preferably, the sealing member 46 is provided with thin walls 54 outside the first and second interlayers 50 and 51, which are trumpet-shaped, and the hydraulic or pneumatic pressure in the cavity of the pump shell 28 deforms the thin walls 54 at different positions to fit the inner wall of the pump shell 28 during the movement of the sealing member 46 in different directions, so as to avoid air or liquid leakage of the pump shell 28.

[0098] It should be noted that the upstream and downstream in the embodiment refer to the relative positions of the flow direction of the liquid in the liquid storage cavity 13 to the liquid outlet 14 by the liquid pump 27, and are independent of the installation direction of the liquid spraying mechanism 7 and the installation direction of the liquid pump 27, that is, regardless of the direction of the liquid spraying mechanism 7 and the liquid pump 27, the flow direction of the cleaning liquid in the liquid storage cavity 13 is fixed, and the flow direction of the cleaning liquid in the embodiment is in sequence of the liquid storage cavity 13, the liquid inlet pipeline 30, the pump shell 28, the liquid outlet pipeline 32 and the liquid outlet 14. Relative to the pump shell 28, the liquid storage cavity 13 and the liquid inlet pipeline 30 are upstream, and the liquid outlet pipeline 32 and the liquid outlet 14 are downstream. Similarly, other positions through which the cleaning liquid flows can also be compared in the upstream and downstream manner.

[0099] Preferably, the third liquid pump 27 is an electric pump installed in or outside the liquid storage cavity 13, and the electric pump is connected with the liquid outlet 14 and drives the cleaning liquid in the liquid storage cavity 13 to the liquid outlet 14 for spraying. Embodiment 3

[0100] The same as embodiment 1, the same part of the embodiment will not be repeated, and only the different part will be described. The difference between the embodiment and embodiment 1 is that the liquid pump 27 is not separately provided in the liquid spraying mechanism 7.

[0101] The first liquid outlet mode in the embodiment is as follows: Figure 18 The liquid spraying mechanism 7 includes a pressing part 12, a shell 18 and a liquid outlet 14. The cavity in the shell 18 forms a liquid storage cavity 13. The liquid outlet 14 is located at the bottom of the shell 18, and the top of the shell 18 is open. The pressing part 12 is provided as a push rod, and the lower end is inserted into the liquid storage cavity 13. The cleaning liquid is squeezed out of the liquid storage cavity 13 by moving the pressing part 12 downward in the liquid storage cavity 13.

[0102] Preferably, the liquid spraying mechanism 7 can supplement the cleaning liquid by separately providing a liquid inlet, or supplement the cleaning liquid by pulling the pressing part 12 upward to make the liquid outlet 14 absorb water from the outside.

[0103] The second liquid dispensing method in this embodiment is that the liquid spraying mechanism 7 includes a pressing part 12, a housing 18, a liquid spraying port 14, and a liquid spraying valve 55. Specifically, the cavity inside the housing 18 forms a liquid storage chamber 13, and the spray nozzle 14 is located at the lower position of the liquid storage chamber 13. A sealing plug 39 is detachably connected to the liquid filling port 38 of the housing 18. After the spray mechanism 7 is installed, the housing 41 body 18 forms a seal, that is, the spray valve 55 can prevent the cleaning liquid from flowing out when the housing 18 is rotated to any angle. The pressing part 12 is made of flexible material. By pressing the pressing part 12, it deforms into the liquid storage chamber 13, reducing the volume of the liquid storage chamber 13 and creating an air pressure difference between the liquid storage chamber 13 and the outside. The spray valve 55 opens due to the air pressure difference and sprays liquid outward. When the pressing part 12 is released, the pressing part 12 deforms back to its original position. After the liquid is sprayed, the internal air pressure of the liquid storage chamber 13 is less 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 pressure of the liquid storage chamber 13 are balanced.

[0104] Preferred, such as Figure 19 The spray mechanism 7 can be configured such that the housing 18 is made of rigid plastic and the pressing part 12 is made of flexible material, and the housing 18 and the pressing part 12 are connected by a sealing method; for example Figure 20 The spraying mechanism 7 can also have its housing 18 made entirely of a flexible material, with a pressing part 12 formed on the surface of the housing 18 where it can be pressed to deform, thereby achieving pressure-driven spraying of liquid; for example Figure 21 The spraying mechanism 7 can also be an integral structure of the housing 18 that is retractable and foldable. The surface of the housing 18 can be pressed to form a pressing part 12, thereby realizing the spraying of liquid by changing the air pressure.

[0105] Furthermore, such as Figure 22 The housing 18 is made of rigid plastic, and the pressing part 12 is made of flexible material or is configured as a retractable and foldable structure. The pressing part 12 is connected to the housing 18 through an air pipe 56. When the pressing part 12 is squeezed from the outside of the housing 18, the air in the pressing part 12 enters the liquid storage chamber 13 through the air pipe 56, squeezing the cleaning liquid out of the spray nozzle 14. After the cleaning liquid is sprayed out, the outside air enters the pressing part 12 and the liquid storage chamber 13 through the pressure difference from the spray valve 55 or the air inlet valve separately provided on the pressing part 12, so as to achieve the pressure balance between the pressing part 12, the liquid storage chamber 13 and the outside. Example 4

[0106] The similarities with Embodiment 1 will not be repeated in this embodiment. Only the differences will be described. The difference between this embodiment and Embodiment 1 is the structure of the mounting platform 19.

[0107] In the embodiment, the mounting platform 19 refers to a device for fixing the connection of the flat mop and the liquid spraying mechanism 7 as a whole. The mounting platform 19 can be arranged on the flat mop, on the liquid spraying mechanism 7, or on both the flat mop and the liquid spraying mechanism 7. After the flat mop and the liquid spraying mechanism 7 are installed, the device for fixing is combined to form the mounting platform 19.

[0108] In the embodiment, the flat mop and the liquid spraying mechanism 7 are two independent individuals during production and processing. After the components of the liquid spraying mechanism 7 are formed, installed, and integrated into a complete liquid spraying module, the liquid spraying mechanism 7 is installed with the flat mop to improve the production, installation, and inspection efficiency of the liquid spraying mechanism 7 and reduce the replacement and scrap costs of the liquid spraying mechanism 7 and the flat mop due to unqualified water test.

[0109] The mounting platform 19 in the embodiment can be implemented in various structures. In some structures, the mounting platform 19 makes the liquid spraying mechanism 7 no longer need to be used with a specially designed flat mop. The mounting platform 19 makes the liquid spraying mechanism 7 adaptable to the flat mop on the market and purchased by the user, so that the application range of the liquid spraying mechanism 7 is wider.

[0110] Preferably, the first mounting platform 19 is arranged as follows: Figures 23-24 The upper part of the water squeezing sleeve 5 is provided with an outwardly protruding raised frame 57. The outer end of the raised frame 57 is flush. The inner side wall of the raised frame 57 is provided with a first protrusion 58 in an L shape. The two directionally extended arms of the first protrusion 58 form a slot 59. The housing 18 of the liquid spraying mechanism 7 is provided with an extension table 60. The side surface of the extension table 60 is provided with a second protrusion 61. During installation, the first protrusion 58 and the second protrusion 61 are misaligned. The extension table 60 is inserted into the raised frame 57. The liquid spraying mechanism 7 is rotated in a predetermined direction to make the second protrusion 61 enter the slot 59 formed by the first protrusion 58, thereby realizing the quick installation and disassembly of the liquid spraying mechanism 7. In this way, the raised frame 57 and the extension table 60 jointly form the mounting platform 19.

[0111] More specifically, in the embodiment, the frame 57 is square, both of the opposite inner side walls of the frame 57 are provided with the first protrusions 58, the two first protrusions 58 are centrally symmetrical, the extension platform 60 is circular 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, the extension platform 60 is inserted into the frame 57 until the extension platform 60 abuts against the frame 57, at this time, the liquid spraying mechanism 7 can be rotated to position the second protrusion 61 into the slot 59, the square of the frame 57 provides the corner area of the frame 57 for the insertion of the second protrusion 61 to form the installation positioning point, that is, other positions except the corners will abut against the second protrusion 61 to prevent the second protrusion 61 from being inserted into the frame 57, thereby simplifying the positioning during installation of the liquid spraying mechanism 7. In addition, in order to avoid the insertion of the second protrusion 61 aligned with the corner away from the slot 59, in the embodiment, the corner position away from the slot 59 is also provided with the anti-stupid position 62, which is realized by being provided with a shape different from the other corner, being provided with an identification, or being provided with a stop block.

[0112] Of course, in other embodiments, such as Figure 25 , the slot 59 of the L type can be provided in one of the frame 57 and the extension platform 60, and the second protrusion 61 is provided on the other one, and the installation positioning is realized by the alignment of the second protrusion 61 and the outer end of the slot 59.

[0113] Preferably, the second installation platform 19 is provided as, such as Figure 26 , the upper part of the water squeezing sleeve 5 is provided with the raised frame 57 protruding outward, the outer end of the frame 57 is flush, the inner side wall of the frame 57 is provided with the internal thread 63, the shell 18 of the liquid spraying mechanism 7 is provided with the extension platform 60, the side surface of the extension platform 60 is provided with the external thread 64, the frame 57 and the extension platform 60 jointly constitute the installation platform 19, during installation, the extension platform 60 is aligned with the frame 57, and the liquid spraying mechanism 7 is screwed with the extension platform 60.

[0114] Preferably, the third installation platform 19 is provided as, such as Figure 27 , the upper part of the water squeezing sleeve 5 is provided with the raised frame 57 protruding outward, the outer end of the frame 57 is flush, the inner side wall of the frame 57 is provided with the male buckle 65, the shell 18 of the liquid spraying mechanism 7 is provided with the extension platform 60, the side surface of the extension platform 60 is provided with the female buckle 66, the frame 57 and the extension platform 60 jointly constitute the installation platform 19, during installation, the extension platform 60 is aligned with the frame 57, and the liquid spraying mechanism 7 is buckled with the extension platform 60.

[0115] Preferably, the fourth installation platform 19 is provided as, one or both of the water squeezing sleeve 5 and the shell 18 is provided with the extension platform 60, and the water squeezing sleeve 5 and the liquid spraying mechanism 7 are fixedly connected by installing screws on the extension platform 60.

[0116] In the above embodiments, all four mounting platforms 19 are configured as detachable structures, allowing the spraying mechanism 7 to be fixedly installed and used in conjunction with the flat mop to spray liquid onto the wiping material 3. Alternatively, the flat mop and the spraying mechanism 7 can be used independently after the spraying mechanism 7 is disassembled. Simultaneously, the raised or extended portions on the mounting platform 19 allow the spraying mechanism 7 to suspend outside the wringer sleeve 5, enabling the upper ends of the mop head 2 and the wiping material 3 to be inserted into the gap between the spraying mechanism 7 and the wringer sleeve 5 for positioning or spraying.

[0117] In other embodiments, the water-squeezing sleeve 5 and the spraying mechanism 7 can be connected in a non-detachable structure by means of riveting, welding, or other methods, based on the frame 57 and the extension platform 60. However, regardless of the structure of the installation platform 19 used, the water-squeezing device 4 and the spraying mechanism 7 must pass a qualified inspection before being assembled into a whole, or they can pass a qualified inspection separately after disassembly.

[0118] All of the above-mentioned installation platforms 19 require a specially made wringer 5 to install the spraying mechanism 7. In order to facilitate the use of the spraying mechanism 7 with ordinary wringer 5 and ordinary mop, the installation platform 19 in this embodiment can also adopt other methods, such as setting the installation platform 19 entirely on the spraying mechanism 7.

[0119] Specifically, such as Figure 28 The housing 18 of the spraying mechanism 7 is provided with an extension platform 60. The extension platform 60 is equipped with clamps, rings 67, straps, pipe clamps, and other clamping structures. The clamps, rings 67, straps, pipe clamps, and other clamping structures fix the spraying mechanism 7 to a regular mop or wringer 5 by wrapping around the mop handle 1 or wringer 5. The elasticity and tightness of the clamping structures can be adjusted to fix the spraying mechanism 7 to mops or wringer 5 of different sizes. The extension platform 60 and the clamping structures together form an installation platform 19. The clamping structures are used to install the spraying mechanism 7 on the mop, and the extension platform 60 is used to control the distance between the spraying mechanism 7 and the mop handle 1 or wringer 5 to avoid protruding parts on the mop affecting the installation of the spraying mechanism 7. It also facilitates the mop head 2 and the wiping material 3 to enter the gap between the spraying mechanism 7 and the mop handle 1 or wringer 5 for positioning and spraying. Even if the installed mop is not equipped with a wringer 4, the installed spray mechanism 7 can spray liquid onto the wiping material 3, and then place the wiping material 3 on the mop bucket or other cleaning devices for cleaning, thereby expanding the range of mops that can be used with the spray mechanism 7.

[0120] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
