[0046] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0047] It should be understood that although terms such as upper, middle, lower, top, one end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, rather than for defining any directional or sequential limitations.

[0048] As Figure 1-9 shown, a spray mop with a compact structure includes:

[0049] A mop main body 1, the interior of which forms a cavity. A hand-held component 2 is connected to the upper part of the mop main body 1. A mop cloth component 3 is provided at the bottom of the mop main body 1. Among them, the hand-held component 2 refers to a rod body connected to the mop main body 1 and a holding part 2.2 for a person to grasp and operate.

[0050] A water tank 4, detachably arranged in the mop main body 1;

[0051] A pump assembly, including a pump body 5 arranged in the mop main body 1, a water outlet pipe component 7 and a water inlet pipe component 6 communicating with the pump body 5, and a pump rod 8 movably arranged in the pump body 5. The water inlet pipe component 6 is connected to the side of the pump body 5 and connected to the inlet of the pump body 5. The upper end of the water inlet pipe component 6 defines a connection port 6.1 on the mop main body 1 for installing the water tank 4. The water outlet pipe component 7 is connected to the bottom of the pump body 5 and connected to the outlet of the pump body 5. The water outlet pipe component 7 forms a water outlet 7.1 on the mop main body 1. The water inlet pipe component 6 connects the pump body 5 and the water tank 4. A transmission rod group 2.1 is arranged in the hand-held component 2 and is in transmission connection with the pump rod 8, and a pressing part 2.3 for actuating the pump rod 8 to perform an axial movement in the pump body 5 is provided. The pressing part 2.3 is arranged on the holding part 2.2. By actuating the pressing part 2.3, the transmission rod group 2.1 is driven, and further the pump rod 8 is actuated to act in the pump body 5 to pump the liquid in the water tank 4 to the water outlet pipe component 7.

[0052] Among them, a piston member 9 is provided in the pump body 5, and a lower connecting seat 9.2 is provided at the bottom of the piston member 9. A first spring 11 is abutted between the lower connecting seat 9.2 and the bottom of the pump body 5. The first spring 11 is used to provide a rebound force for the pump rod 8 after being pressed. An upper connecting seat 9.1 is provided on the upper part of the piston member 9. The upper connecting seat 9.1 is fixedly matched with the pump rod 8 so that the pump rod 8 and the piston member 9 form a transmission match. The piston member 9 has a radially extending connecting edge 9.3. The upper connecting seat 9.1 and the lower connecting seat 9.2 are respectively arranged at the upper and lower ends of the connecting edge 9.3. A sealing skirt 9.4 is extended on the circumferential side of the connecting edge 9.3. The sealing skirt 9.4 extends about the axial ends, and the sealing skirt 9.4 has a tendency to expand radially, so that the sealing skirt 9.4 abuts against the inner wall of the pump body 5, thereby ensuring the sealing of the pump body 5 when the piston member 9 moves axially. At the same time, the piston member 9 occupies most of the space at the upper end of the pump body 5, realizing a close fit between the piston member 9, the pump rod 8 and the pump body 5.

[0053] Among them, the gripping portion 2.2, the pressing portion 2.3 and the transmission rod assembly 2.1 have been fully applied in the art and will not be described in detail here.

[0054] As a further implementation method for the cooperation between the pump body 5 and the pump rod 8 and the piston member 9, the upper end of the pump body 5 is open for the pump rod 8 to be placed therein, and a pump cover 10 is provided at the upper end of the pump body 5. The pump cover 10 has an end cover body that is sealed and fitted on the port of the outer wall of the pump body 5, and a piston port 10.1 for the pump rod 8 to pass therethrough, and the diameter of the piston port 10.1 decreases toward the pressing direction. Further, a disc-shaped abutment portion 8.1 is provided at the upper end of the pump rod 8, and the disc-shaped abutment portion 8.1 is used to abut and cooperate with the transmission rod group 2.1, and a guide channel matching the contour of the disc-shaped abutment portion 8.1 is provided in the mop body 1. In this way, the lower end of the pump rod 8 is retained by the piston member 9 that is tightly fitted with the inner wall of the pump body 5, and the middle section of the pump body 5 is retained by the piston port 10.1 on the pump cover 10, thereby improving the tightness of the pump rod 8 during axial movement in the pump body 5.

[0055] Preferably, the end surface of the upper connecting seat 9.1 is arranged opposite to the lower end of the piston opening 10.1 of the pump cover 10 to prevent the pump rod 8 from axially escaping.

[0056] from Figure 7As can be seen, in some other embodiments, to further optimize the operating feel of the pump rod 8, a flexible gasket ring 10.2 is provided at the bottom of the piston port 10.1. The flexible gasket ring 10.2 abuts against the upper connecting seat 9.1 and extends radially along the inner wall of the pump body 5. In addition, the flexible gasket ring 10.2 is also in contact with the upper end of the sealing skirt 9.4 in the initial position. In this way, the collision sound when the pump rod 8 rebounds actuated by the first spring 11 is effectively reduced, the operating noise of the mop main body 1 is reduced, and at the same time, the flexible gasket ring 10.2 also strengthens the sealing between the pump cover 10 and the pump body 5, reducing the possibility of liquid leakage inside the pump.

[0057] Specifically, a water passing seat 5.1 is provided at the bottom of the pump body 5, and a water passing channel 5.2 communicating with the water outlet pipe fitting 7 is provided on the water passing seat 5.1. The first spring 11 is sleeved on the water passing seat 5.1.

[0058] As Figure 2 , Figure 4 , Figure 5 and Figure 9 shown, the present invention also provides an installation structure of the mop main body 1. Specifically, a front shell 1.1 is detachably provided at the front end of the mop main body 1. The front shell 1.1 defines a first installation cavity 1.2 for placing the pump assembly at the front end of the mop main body 1. Thanks to the connection method of the pipe fittings between the water inlet pipe fitting 6, the water outlet pipe fitting 7 and the pump body 5, the modular setting of the pump assembly is realized. The pump assembly can be directly placed and installed in the mop main body 1 through the open first installation cavity 1.2, and then the front shell 1.1 is buckled. At the same time, the disassembly of the front shell 1.1 also facilitates the maintenance and replacement of the internal components of the mop main body 1, improving the assembly efficiency.

[0059] Furthermore, a second installation cavity 1.3 for placing the water supply tank 4 and a third installation cavity 1.4 for placing the pump rod 8 and the hand-held assembly 2 are provided at the upper end of the mop main body 1. The second installation cavity 1.3 and the third installation cavity 1.4 are open upward. Among them, the connection port 6.1 of the water outlet pipe fitting 7 is located in the second installation cavity 1.3, so that the water tank 4 is installed vertically, and the installation and water outlet are more smooth and convenient. A guiding channel is formed in the third installation cavity 1.4. After the assembly of the pump assembly is completed, only the pump rod 8 needs to be inserted into the pump body 5 through the guiding channel. Since the upper end of the pump rod 8 is a disc-shaped abutting portion 8.1, only the hand-held assembly 2 needs to be further connected to the opening of the third installation cavity 1.4.

[0060] Further referring to Figure 5 , in some other embodiments, to further improve the installation convenience of the mop main body 1, an installation rib group extending along the opening direction is provided in the first installation cavity 1.2. The installation rib group includes:

[0061] The first rib group includes the first ribs 1.5 arranged at intervals up and down, and the support ribs 1.8 arranged below the first ribs 1.5. The water inlet fitting 6 is provided with a first ring edge 6.3, and the first ring edge 6.3 is inserted between the first ribs 1.5. The support ribs 1.8 support the bottom of the water outlet fitting 7, and the water inlet fitting 6 has a water inlet end 6.2 arranged along the extending direction of the first ribs 1.5, and the water inlet end 6.2 is inserted and communicated with the pump body 5, so that the water inlet fitting 6 can be directly inserted and installed and fixed in the opening direction of the first installation cavity 1.2;

[0062] The second rib group includes the second ribs 1.6 arranged at intervals from the support ribs 1.8. The pump body 5 is provided with a second ring edge 8.2, and the support ribs 1.8 extend towards the second ribs 1.6. The second ring edge 8.2 is inserted between the support ribs 1.8 and the second ribs 1.6, so that the pump body 5 can be positioned in the first installation cavity 1.2 through the second ring edge 8.2 and is ready to be connected with the water inlet fitting 6;

[0063] The third rib group includes a plurality of third ribs 1.7 arranged at intervals up and down. The third ribs 1.7 are provided with installation grooves 1.9 about the contours of the pump body 5 and the water outlet fitting 7. Moreover, the support ribs 1.8 support the pump body 5 and the water inlet fitting 6 at the same time, so that the pump body 5, the water inlet fitting 6 and the water outlet fitting 7 are directly placed in the first installation cavity 1.2 in a pre-modular assembly manner and are further positioned and fixed through the internal third rib group and the installation grooves 1.9.

[0064] As Figure 7 shown, in some other embodiments, to further improve the structural compactness inside the pump body 5 and the reliability of the movement of the piston member 9. Specifically, a support step 5.3 is provided at the bottom of the pump body 5, a lining tube 12 is provided on the inner wall of the pump body 5 and abuts against the support step 5.3, a support platform 12.1 corresponding to the lower part of the connecting edge 9.3 is provided at the upper end of the lining tube 12, and a second spring 13 is abutted between the support platform 12.1 and the connecting edge 9.3. The diameter of the second spring 13 is larger than that of the first spring 11, and the inner surface of the support platform 12.1 is close to the outer surface of the first spring 11.

[0065] Through the above improvements, the lining tube 12 further compresses the internal space of the pump body 5, and the inner surface of the support platform 12.1 further limits the outer position of the first spring 11, reducing the radial movement of the first spring 11. At the same time, a second spring 13 is abutted between the support platform 12.1 and the connecting edge 9.3. The second spring 13 provides a further acting force for the return of the pump rod 8 and the transmission rod group 2.1 and improves the user's operation feel to reduce the situation where the pump rod 8 does not return in place.

[0066] As Figure 8As shown, specifically, the support table 12.1 is spaced from the inner surface of the pump body 5, and an annular guide groove 14 is formed between the support table 12.1 and the inner surface of the pump body 5. The bottom of the sealing skirt 9.4 is always placed in the annular guide groove 14. The depth of the annular guide groove 14 can at least accommodate the sealing skirt 9.4 in the pressed state. And a stainless steel ring 9.5 is provided at the bottom of the sealing skirt 9.4. The stainless steel ring 9.5 is preferably embedded in the bottom of the sealing skirt 9.4 and provides a counterweight for the sealing skirt 9.4 to guide the movement of the sealing skirt 9.4 in the annular guide groove 14. At the same time, the stainless steel ring 9.5 also keeps the expanded posture of the sealing skirt 9.4 to prevent the sealing skirt 9.4 from being excessively squeezed and deformed in the annular guide groove 14.

[0067] Further referring to Figure 8 , specifically, a positioning convex portion 5.4 is provided on the support step 5.3, and a positioning concave portion 12.2 is provided at the bottom of the inner liner 12. The positioning concave portion 12.2 and the positioning convex portion 5.4 are arranged radially to position the inner liner 12 on the support step 5.3. In this way, the inner liner 12 is reliably positioned in the pump body 5 and provides an anti-rotation function for the inner liner 12.

[0068] Specifically, a retaining ring 15 is provided at the bottom of the connecting edge 9.3 and is spaced between the first spring 11 and the second spring 13. The retaining ring 15 is also formed on the support table 12.1 to position the second spring 13 and avoid interference between the first spring 11 and the second spring 13.

[0069] Specifically, the connecting edge 9.3 approaches the inner wall of the pump body 5 to maintain the extended posture of the sealing skirt 9.4.

[0070] This specific embodiment is only an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
