Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and in particular to a pole connection structure for a spray mop. Background Technology

[0002] Existing spray mops generally have similar structures, including a mop handle, a mop disc movably connected to the handle, a water tank on the handle, and a water pump connected to the tank. The pump is also connected to a nozzle for spraying water. The pump is connected to a wrench mechanism that operates to draw water from the tank and ultimately spray it from the nozzle. The wrench mechanism operates the pump, causing the water in the tank to spray out through the nozzle. A drawback of this type of spray mop is that the water tank, located on the handle, forms a protruding section. To ensure sufficient water storage, this protrusion is more noticeable, making the entire mop bulky, taking up a lot of space, and hindering packaging.

[0003] To address this, spray mops with internal water storage have emerged, such as the self-spraying mop with a water-spraying function disclosed in patent number CN201720408144.X. This mop handle features a spray structure comprising an inner tube, a water pump, and a nozzle. The nozzle is located at the lower part of the mop handle, the inner tube is inside the handle, and the water pump is located inside the handle and below the inner tube. The water pump is connected to the outlet end of the inner tube and is connected to a drive structure that draws water from the inner tube and sprays it through the nozzle. The inner tube inside the mop handle serves as a water storage tank, allowing water to be stored throughout the entire handle. This eliminates the need for a large external water tank without affecting the water storage capacity, resulting in a compact mop size while maintaining sufficient water storage. However, to prevent leakage, the inner tube is a single piece of stainless steel, resulting in a relatively long overall length. Since the inner tube is located inside the mop handle, the handle itself is also a single tubular component. This results in a very long overall product length, which is not conducive to packaging and transportation. Summary of the Invention

[0004] The purpose of this utility model is to provide a pole connection structure for a spray mop, which can solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A pole connection structure for a spray mop includes a first pole and a second pole. The first pole and the second pole are hollow structures. A first transmission rod is movably disposed inside the first pole, and a second transmission rod is movably disposed inside the second pole. A channel for liquid to pass through is formed between the first transmission rod and the first pole, and between the second transmission rod and the second pole.

[0006] A connector is fixed in the first rod body. The connector is a hollow structure. A connecting push rod is movably disposed inside the connector. A channel for liquid to pass through is also formed between the connecting push rod and the connector. The head of the connector is located inside the first rod body. A first sealing element is sealed between the head of the connector and the first rod body. The tail of the connector extends out of the first rod body and is inserted into the second rod body. A second sealing element is sealed between the tail of the connector and the second rod body.

[0007] The first rod is movably fitted with a first protective sleeve. The first protective sleeve has an internal thread at one end near the second rod. The first protective sleeve also has a limiting step located inside the internal thread. The second rod is fixedly fitted with a second protective sleeve. The second protective sleeve has an external thread that matches the internal thread at one end near the first rod.

[0008] The connector has a protruding limiting ring in the middle, located between the first rod and the second rod. The outer diameter of the limiting ring is larger than the inner diameter of the second rod and the inner diameter of the limiting step. The connector has a first limiting part, and the second sheath and / or the second rod have a second limiting part that matches the first limiting part.

[0009] When the first rod body and the second rod body are connected, the tail of the connector is inserted into the second rod body, the end of the second rod body abuts against one side of the limiting ring, and the limiting step abuts against the other side of the limiting ring. The first sleeve and the second sleeve are connected by the internal thread and the external thread. The first limiting part and the second limiting part are connected to restrict the rotation of the first rod body relative to the second rod body. The connecting push rod is connected between the first transmission rod and the second transmission rod. The channel in the connector is connected between the channels of the first rod body and the second rod body.

[0010] Preferably, the inner wall of the second sheath has at least one protruding locking protrusion, and the second rod has a locking hole opposite to the locking protrusion. The locking protrusion is placed in the locking hole to fix the second sheath to the second rod.

[0011] Preferably, the card protrusion has inclined surfaces on both sides parallel to the axial direction of the second rod.

[0012] Preferably, the second sheath has an axial strip opening on the external thread portion that is offset from the locking protrusion.

[0013] Preferably, the first limiting part is a limiting protrusion protruding from the outer wall of the middle part of the connector, and the second limiting part is a limiting opening provided on the second sheath and / or the second rod body.

[0017] Preferably, the first sheath has anti-slip texture.

[0018] Preferably, the inner wall of the second rod body is provided with an anti-detachment protrusion to prevent the second transmission rod from detaching.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: Using the above structure, the spray mop's handle can be divided into at least two sections and detachably connected together. The connecting parts are sealed to the corresponding handle sections, ensuring internal communication between the two sections to form a water storage space. The two drive rods transmit force through a connecting push rod to control the water pump. Therefore, when not in use, the handle and drive rods of this utility model can be disassembled into at least two sections, significantly shortening the length, reducing packaging volume, and facilitating packaging and transportation. The water storage space formed within the connected handle ensures no leakage. Without affecting the water storage capacity, there is no need for a large external water tank, nor any additional obtrusive structure. The overall structure is more compact, and the connected drive rods can reliably transmit the force driving the water pump, resulting in a simple and compact structure. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a pole connection structure for a spray mop, including a first pole 1 and a second pole 2. The first pole 1 and the second pole 2 are hollow structures. A first transmission rod 3 is movably provided inside the first pole 1, that is, the first transmission rod 3 can slide along the axial direction of the first pole 1. A second transmission rod 4 is movably provided inside the second pole 2, that is, the second transmission rod 4 can slide along the axial direction of the second pole 2. A channel for liquid to pass through is formed between the first transmission rod 3 and the first pole 1, and between the second transmission rod 4 and the second pole 2.

[0025] A connector 5 is fixed in the first rod body 1. The connector 5 is a hollow structure. A connecting push rod 6 is movably disposed inside the connector 5, that is, the connecting push rod 6 can slide along the axial direction of the connector 5. The connecting push rod can be independently disposed in the connector, that is, the connecting push rod and the first transmission rod or the second transmission rod are separate structures; the connecting push rod can also be integrally formed with the first transmission rod and placed in the connector; or the connecting push rod can be integrally formed with the second transmission rod and extend out of the second rod body. When the first rod body and the second rod body are connected, the connecting push rod is inserted into the connection. A channel for liquid to pass through is also formed between the connecting push rod 6 and the connector 5. The head of the connector 5 is located inside the first rod body 1. A first sealing element 7 is sealed between the head of the connector 5 and the first rod body 1. The tail of the connector 5 extends out of the first rod body 1 and is inserted into the second rod body 2. A second sealing element 8 is sealed between the tail of the connector 5 and the second rod body 2. The first sealing element 7 and the second sealing element 8 are preferably sealing rings.

[0026] The first rod body 1 is movably fitted with a first protective sleeve 9, that is, the first protective sleeve 9 can slide along the axial direction of the first rod body 1 and rotate relative to the first rod body 1. The first protective sleeve 9 has an internal thread 10 at one end near the second rod body 2. The first protective sleeve 9 also has a limiting step 11 located inside the internal thread 10. The second rod body 1 is fixed with a second protective sleeve 12. The second protective sleeve 12 has an external thread 13 that matches the internal thread 10 at one end near the first rod body 1.

[0027] The connector 5 has a protruding limiting ring 14 located between the first rod 1 and the second rod 2. The outer diameter of the limiting ring 14 is larger than the inner diameter of the second rod 2 and the inner diameter of the limiting step 14. The connector 5 has a first limiting part, and the second sheath 12 or / and the second rod 2 have a second limiting part that matches the first limiting part.

[0028] When the first rod 1 and the second rod 2 are connected, the tail of the connector 5 is inserted into the second rod 2, the end of the second rod 2 abuts against one side of the limiting ring 14, and the limiting step 11 abuts against the other side of the limiting ring 14. The first sleeve 9 and the second sleeve 12 are connected by the internal thread 10 and the external thread 13. The first limiting part and the second limiting part are connected to restrict the rotation of the first rod 1 relative to the second rod 2. The connecting push rod 6 is connected between the first transmission rod 3 and the second transmission rod 4. The channel in the connector 5 is connected between the channels of the first rod 1 and the second rod 2.

[0029] During transportation, the first transmission rod 3 is installed in the first rod body 1, the connecting piece 5 is fixed to the first rod body 1 as a whole, and the first sheath 9 is fitted over the first rod body 1, thus forming a single rod section. The second transmission rod 4 is installed in the second rod body 2, and the second sheath 12 is fixed to the second rod body 2 as a whole, thus forming another single rod section. This allows the rod body and transmission rod to be disassembled into at least two sections when not in use, significantly shortening the length, reducing packaging volume, and facilitating packaging and transportation. During assembly, the tail of the connecting piece 5 is directly inserted into the second rod body 2 until the end of the second rod body 2 abuts against one side of the limiting ring 14. Then, the first sheath 9 is screwed down, causing the internal thread 10 of the first sheath 9 to engage with the external thread 13 of the second sheath 12, until the limiting step 11 of the first sheath 9 abuts against the other side of the limiting ring 14. The limiting ring 14 is then clamped between the limiting step 11 and the second rod body 2, thereby achieving the connection between the first rod body 1 and the second rod body 2. At this time, the first limiting part and the second limiting part cooperate to restrict the rotation of the first rod 1 relative to the second rod 2. The first sealing element 7 on the connecting part 5 seals between the first rod 1 and the connecting part 5, and the second sealing element 8 on the connecting part 5 seals between the second rod 2 and the connecting part 5. This ensures that the two rod sections are internally connected to form a water storage space. The two ends of the connecting push rod 6 are respectively connected between the first transmission rod 3 and the second transmission rod 4. The operating force of the wrench mechanism can be transmitted sequentially through the first transmission rod 3, the connecting push rod 6, and the second transmission rod 4 to control the operation of the water pump. The water storage space formed in the connected rod body ensures that it does not leak. Without affecting the water storage capacity, there is no need for a large external water tank, and there is no additional obtrusive structure. The overall structure is smaller and more compact. The connected transmission rod can reliably transmit the force to drive the water pump. The structure is simple and compact.

[0030] Preferably, the inner wall of the second sheath 12 has at least one latching protrusion 15, and the second rod 2 has a latching hole 16 opposite to the latching protrusion 15. The latching protrusion 15 is placed in the latching hole 16 to fix the second sheath 12 and the second rod 2. Generally, there are two latching protrusions 15 and they are evenly distributed on the inner wall of the second sheath 12. There are also two corresponding latching holes 16 on the second rod 2.

[0031] Preferably, the two sides of the latching protrusion 15 that are parallel to the axial direction of the second rod 2 are formed with inclined surfaces to facilitate the latching protrusion 15 to be engaged and disengaged from the latching hole 16.

[0032] Preferably, the second sheath 12 has an axial strip opening 17 on the external thread portion 13 that is offset from the locking protrusion 15. Due to the presence of the axial strip opening 17, the external thread portion 13 can be appropriately elastically deformed when the locking protrusion 15 is engaged or disengaged from the locking hole 16, which facilitates the installation and disassembly of the second sheath 12 and the second rod 2.

[0033] Preferably, the first limiting part is a limiting protrusion 18 protruding from the outer wall of the middle part of the connector 5, and the second limiting part is a limiting opening 19 provided on the second sheath 12 and / or the second rod 2. The limiting protrusion 18 is inserted into the limiting opening 19 to limit the rotation of the first rod 1 relative to the second rod 2. When the tail of the connector 5 is inserted into the second rod 5, the limiting protrusion 18 is inserted into the limiting opening 19, which can prevent the first rod 1 from rotating relative to the second rod 2 during mopping, making it convenient to use.

[0034] Preferably, a positioning protrusion 20 is provided on the outer wall of the middle part of the connector 5, and a positioning opening 21 is provided on the first rod body 1, with the positioning protrusion 20 placed in the positioning opening 21. The connector 5 and the first rod body 1 can be connected as one piece by a punching process or fixed as one piece by screws. The positioning protrusion 20 placed in the positioning opening 21 can not only play a positioning role when the connector 5 and the first rod body 1 are assembled, but also prevent the first rod body 1 from rotating relative to the second rod body 2 during the mopping process.

[0035] Preferably, when the connecting push rod and the first transmission rod or the second transmission rod are separate structures, the two ends of the connecting push rod 6 are formed with pushing parts 22, and the outer diameter of the pushing part 22 at one end is larger than the inner diameter of the connecting member 5, and the outer diameter of the pushing part 22 at the other end is smaller than the inner diameter of the connecting member 5. The pushing part 22 at the small end of the connecting push rod 6 can slide freely in the connecting member 5 and can extend from the tail of the connecting member 5, while the pushing part 22 at the large end of the connecting push rod 6 cannot enter the connecting member 5. When the connecting member 5 and the first rod body 1 are assembled into one piece, the pushing part 22 at the large end of the connecting push rod 6 is placed in the first rod body 1, thereby preventing the connecting push rod 6 from coming out of the connecting member 5.

[0036] Preferably, the first protective sleeve 9 is provided with anti-slip texture 23, which has an anti-slip effect and makes it easy to rotate the first protective sleeve 9.

[0037] Preferably, the inner wall of the second rod body 2 is provided with an anti-detachment protrusion 24 for preventing the second transmission rod 4 from detaching. When the second transmission rod 4 is installed in the second rod body 2, it can prevent the second transmission rod 4 from detaching from the second rod body 2.

[0038] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
