[0031] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] In order to prevent the growth of bacteria and achieve the goal of not needing to be cleaned, a type of disposable cleaning brush has appeared on the market. Such cleaning brushes can be divided into toilet brushes for cleaning toilets, pot brushes for cleaning pots, and floor brushes for cleaning floors, etc. according to their usage.

[0034] This type of cleaning brush typically includes a handle, a push rod, and a clamping structure. The clamping structure is suitable for clamping and loosening the brush head. One end of the push rod is connected to the clamping structure, and the other end is connected to a button. The force of the button is transmitted to the push rod, which controls the clamping structure to loosen or clamp the brush head. The push rod includes an upper push rod and a lower push rod, and a clamping structure is provided between the upper and lower push rods to securely connect the upper and lower push rods. However, the clamping structure used in the prior art for the upper and lower push rods can cause the upper and lower push rods to detach during actual use, causing inconvenience to the user.

[0035] In view of this, the present application provides an operating handle for a cleaning brush, which arranges a clamping structure and a snap-fit ​​structure between the upper push rod and the lower push rod, so that the upper push rod and the lower push rod are connected by the clamping structure and are snapped together by the snap-fit ​​structure to prevent the upper push rod and the lower push rod from detaching in a direction parallel to the length of the push rod. The present application adopts a double connection method for the upper push rod and the lower push rod to prevent the upper push rod and the lower push rod from detaching during use, thereby improving the user experience.

[0036] Specifically, the present application provides an operating handle for a cleaning brush, comprising: a handle, a push rod, and a clamping structure. The push rod is slidably disposed within the handle, and comprises an upper push rod and a lower push rod detachably connected along the length direction. A connector is disposed on one of the upper push rod and the lower push rod, and a first clamping member for clamping the connector is disposed on the other. The connector is provided with a snap-fit ​​portion, and the first clamping member is provided with a mating portion corresponding to the snap-fit ​​portion. When the upper push rod and the lower push rod are docked, the first clamping member clamps the connector to connect the upper push rod and the lower push rod, and the snap-fit ​​portion engages with the mating portion to prevent the first clamping member and the connector from disengaging in a direction parallel to the length of the handle. The clamping structure is disposed at the bottom of the handle and the push rod, and is used to clamp or release a brush head of the cleaning brush. The clamping structure has a locking position and an unlocking position. When the clamping structure is in the locking position, the brush head is locked to the clamping structure. When the clamping structure is in the unlocking position, the brush head can be detached from the clamping structure.

[0037] Among them, the handle rod can be set to be separated up and down according to needs, that is, it can be set to an upper handle rod and a lower handle rod corresponding to the upper push rod and the lower push rod, or it can be set to be separated front and back, that is, it can be set to a left handle rod and a right handle rod, or it can be set to a combination of upper and lower separation and front and back separation. The upper handle rod and the lower handle rod or the left handle rod and the right handle rod can be fixed by plugging, snap connection, threaded connection, magnetic connection, adhesive bonding, hot melt bonding, etc., which will not be repeated here.

[0038] In some embodiments, the upper push rod is provided with a connector, and the lower push rod is provided with a first clamping member for clamping the connector, or the lower push rod is provided with a connector, and the upper push rod is provided with a first clamping member for clamping the connector. The connector can be configured as any shape as required, as long as the corresponding first clamping member can clamp the connector when the connector is inserted therein. For example, the cross-sectional shape of the connector can be triangular, circular, elliptical, trapezoidal, or polygonal, etc., which will not be further described here.

[0039] In some embodiments, the first clamping member includes a plurality of movably arranged jaws, and the matching portion is provided on the jaws. When the connector is inserted between the plurality of jaws, the jaws clamp the connector and the matching portion is engaged with the locking portion. The plurality of jaws can move relative to or away from each other. When the connector is inserted between the plurality of jaws, the jaws are stretched apart by the connector and move away from each other. After the connector is inserted, the jaws can move relative to each other by relying on external force or their own elastic reset force, thereby clamping the connector. In order to simplify the structure and reduce costs, in some examples, the jaws include two, and the opposing surfaces of the two jaws have positioning grooves corresponding to the structure of the connector. The matching portion is provided on the positioning groove, and the locking portion is provided on the side of the connector facing the positioning groove. The shape of the positioning groove can be set according to the shape of the connector so that the connector can fit tightly with the positioning groove. For example, the connector is set to a pie-shaped structure, and the positioning groove is set to a circular structure corresponding to the pie-shaped structure.

[0040] In order to prevent the connector and the first clamping member from separating from each other due to external forces after connection, in some embodiments, a snap-fitting portion is provided on the connector, and a matching portion corresponding to the snap-fitting portion is provided on the first clamping member. This allows the upper push rod and the lower push rod to be connected by the clamping structure formed by the first clamping member and the connector, while also preventing the first clamping member and the connector from separating in a direction parallel to the length of the handle rod under the clamping action of the clamping structure formed by the snap-fitting portion and the matching portion. In some examples, the snap-fitting portion is configured as a buckle, and the matching portion is configured as a locking hole. When the connector is inserted into the first clamping member, the buckle provided on the connector is engaged with the locking hole provided on the first clamping member, so that the connector and the first clamping member are engaged. In other examples, the snap-fitting portion is provided with a first locking surface that is angled with the length direction of the push rod, and the matching portion is provided with a second locking surface corresponding to the first locking surface. The snap-fitting portion and the matching portion are engaged via the first locking surface and the second locking surface. The angle is set to be an acute angle or a right angle with respect to an axis parallel to the push rod and toward the bottom of the push rod, so as to enhance the interaction force between the engaging portion and the mating portion, thereby preventing the upper push rod and the lower push rod from separating when the lower push rod is pulled down. In addition, when the angle is set to be an obtuse angle with respect to an axis parallel to the push rod and toward the bottom of the push rod, the engaging effect between the engaging portion and the mating portion can be enhanced by providing anti-slip grooves or the like on the engaging surface.

[0041] In some embodiments, the connecting head is configured as a structure based on a pancake shape with a locking portion provided at the end away from the clamping jaw, the locking portion is configured as a groove, the first locking surface is a surface on the groove perpendicular to the length direction of the push rod, the matching portion is configured as a boss on the positioning groove that matches the groove, and the second locking surface is a surface on the boss perpendicular to the length direction of the push rod, so as to simplify the structure and reduce manufacturing costs while enhancing the force between the locking portion and the matching portion.

[0042] In some embodiments, the front end of the first clamping member has a first guide surface for the connector to slide, and the first guide surface gradually tilts toward the positioning groove along the insertion direction of the connector, so that the connector can smoothly extend into the first clamping member.

[0043] In other embodiments, the outer end of the first clamping member is provided with a relief portion. When the first clamping member is deployed within the handle to clamp the connector, the relief portion is used to allow the first clamping member to avoid the inner wall of the handle. The provision of the relief portion ensures that the deployment of the first clamping member is not restricted by the inner wall of the handle, facilitating deployment to clamp the first clamping member inserted therein.

[0044] Considering the length requirements of the cleaning brush during use and the packaging requirements for transportation, in some embodiments, the handle includes an upper handle and a lower handle, with the upper push rod and the lower push rod respectively positioned within the upper and lower handles. The upper and lower handles are pluggable, wherein the outer diameter of the upper end of the lower handle is smaller than the inner diameter of the lower end of the upper handle, so that the upper end of the lower handle can be plugged into the upper handle. The first clamping member is disposed on the lower push rod, and the connector is disposed on the upper push rod. In some examples, the upper and lower handles are pluggably connected via a snap assembly. For example, the upper handle has a snap groove, and the lower handle has a snap, the front end of the snap engaging the snap groove to lock the upper and lower handles together. In some examples, the upper end of the lower handle has a clearance groove for the outer end of the first clamping member to extend. When the upper and lower handles are plugged together and the first clamping member is clamped against the connector, the inner wall of the upper handle presses against the first clamping member. On the one hand, the avoidance groove can expand the deployment range of the first clamping part so that the connecting head can extend into the first clamping part. On the other hand, when the upper handle rod and the lower handle rod are connected, the inner wall of the upper handle rod can press the first clamping part tightly, further preventing the connecting head from falling out of the first clamping part.

[0045] In yet other embodiments, the outer end of the first clamping member is provided with a second guide surface for sliding the lower end of the upper handle, the second guide surface gradually protruding outward from the outer wall of the lower handle along the insertion direction of the connector, and the second guide surface is used to guide the upper handle to slide and compress the first clamping member. In the case where the outer end of the first clamping member is provided with an escape portion, in some embodiments, the escape portion is provided on the second guide surface.

[0046] In some embodiments, a connecting hole and an operating key are provided on the upper portion of the handle, and the operating key is transmission-connected to the upper push rod through the connecting hole. In some examples, the operating key is provided with a first mating surface, and the upper push rod is provided with a second mating surface that slidably engages with the first mating surface. When the operating key moves in a direction perpendicular to the handle, the second mating surface slides relative to the first mating surface, so that the upper push rod moves in a direction parallel to the handle. In other examples, the operating key is provided with a push plate and a connecting portion, wherein the push plate slidably engages with the connecting hole on the handle, one end of the connecting portion is connected to the push plate, and the other end passes through the connecting hole and engages with the upper push rod, so that when the push plate slides in the connecting hole, the connecting portion drives the push rod to move.

[0047] In some embodiments, a reset member is provided between the handle and the push rod for driving the push rod to reset, so as to automatically switch the clamping structure in the unlocked position to the locked position for user convenience. For example, the reset member is configured as a spring sleeved on the upper push rod, and the upper push rod is provided with an abutment flange for limiting the spring, one end of the spring abuts against the abutment flange, and the other end of the spring abuts against the top wall of the handle. In some examples, under the action of the operating key, the upper push rod is pushed toward the top of the handle rod to move the clamping structure to the unlocked position, at which time the spring is compressed. When the force on the operating key is released, the spring, due to its own deformation, exerts a force on the upper push rod toward the bottom of the handle rod, causing the lower push rod to move downward, and the clamping structure switches to the locked position.

[0048] In some embodiments, the clamping structure includes a clamping member connected to the lower end of the lower push rod and a locking portion arranged at the bottom of the handle rod, one of the clamping member and the locking portion is provided with a sliding pin, and the other is provided with a sliding groove, wherein the locking portion is provided on the inner wall of the handle rod, or the handle rod includes a clamping cap movably provided at the bottom end of the handle rod, and the locking portion is provided on the clamping cap. The clamping member and the locking portion cooperate with each other through the sliding groove and the sliding pin to enable the clamping structure to clamp or release the brush head. In some examples, the clamping member is hinged to the lower push rod, for example, the clamping member includes a first clamping portion and a second clamping portion arranged opposite to each other, the top ends of the first clamping portion and the second clamping portion are provided with a hinge hole, the bottom end of the lower push rod is provided with a hinge shaft corresponding to the above-mentioned hinge hole, and the first clamping portion and the second clamping portion are hinged through an axis hole structure. In other examples, the clamping member and the lower push rod are formed as an integral structure, and the clamping member includes a first clamping portion and a second clamping portion arranged opposite to each other, and the connecting portions between the first clamping portion and the second clamping portion and the lower push rod are made of bendable material. When the clamping structure changes between the locked position and the unlocked position, the first clamping portion and the second clamping portion can move away from or relative to each other due to the bending properties of the material.

Figures 1 to 5 As shown, in the present application, the cleaning brush includes a brush head 10 and an operating handle 20 of the cleaning brush, wherein the operating handle 20 of the cleaning brush includes a handle rod, a push rod, and a clamping structure. In this example, the handle rod includes an upper handle rod 31 and a lower handle rod 32. The outer diameter of the upper end of the lower handle rod 32 is smaller than the inner diameter of the lower end of the upper handle rod 31. The lower end of the upper handle rod 31 is provided with a buckle groove 311, and the upper end of the lower handle rod 32 is provided with a buckle 321. The lower handle rod 32 is inserted into the upper handle rod 31 and fixedly connected via the buckle groove 311 and the buckle 321. In addition, the upper handle rod 31 is also provided with a connecting hole 312 for cooperating with the operating key 70, and the lower handle rod 32 is provided with an avoidance groove 322 for use with the first clamping member 421 described below. The push rod includes an upper push rod 41 and a lower push rod 42. The upper push rod 41 and the lower push rod 42 are slidably arranged within the handle rod. Among them, an abutment flange 412 is provided on the upper push rod, and the reset member 60, that is, the spring 60 is arranged between the abutment flange 412 at the upper end of the upper push rod and the inner top wall of the upper handle rod 31, so as to automatically convert the clamping structure in the unlocked position to the locked position.

[0051] Please refer to Figure 3 、 Figure 6 and Figure 7 ,in, Figure 3 An exploded view of the operating handle of the cleaning brush provided in an embodiment of the present application; Figure 6 for Figure 3 A partial enlarged view of the first clamping member and the connecting head; Figure 7 for Figure 6A partial schematic diagram of the upper and lower push rods after they are connected. As shown in the figure, a connector 411 is provided on the upper push rod 41, and a first clamping member 421 for clamping the connector 411 is provided on the lower push rod 42. The first clamping member 421 includes two movable clamping jaws 421a. The connector 411 is arranged in a circular shape with a groove 411a provided at one end away from the clamping jaws 421a. The groove 411a includes a first clamping surface 413 perpendicular to the length direction of the upper push rod. The opposing surfaces of the two clamping jaws 421a are provided with a positioning groove 421b corresponding to the structure of the connector 411. The positioning groove 421b is also provided with a boss 421f that cooperates with the groove 411a. The boss 421f includes a second clamping surface 422 perpendicular to the length direction of the lower push rod 42. When the first connector 411 is inserted into the clamping jaw 421a, the first engaging surface 413 of the groove 411a and the second engaging surface 422 of the boss 421f come into contact, and the groove 411a and the boss 421f are engaged. In addition, the front end of the clamping jaw 421a has a first guide surface 421c for the sliding of the connector 411. The first guide surface 421c gradually tilts toward the positioning groove 421b along the insertion direction of the connector 411, so that the connector 411 can be smoothly inserted into the clamping jaw 421a. The outer end of the clamping jaw 421a is also provided with an avoidance portion 421g. When the clamping jaw 421a is expanded in the handle to clamp the connector 411, the avoidance portion 421g is used to allow the clamping jaw 421a to avoid the inner wall of the handle. In the case where the lower handle 32 is provided with the escape groove 322, the escape groove 322 and the escape portion 421g can be provided simultaneously or alternatively, and both are used to avoid the inner wall of the handle when the clamping jaws 421a are deployed. In addition, the escape groove 322 provided on the lower handle 32 allows the outer ends of the clamping jaws 421a to extend. When the upper and lower handles 31 and 32 are connected and the clamping jaws 421a clamp the connector 411, the inner wall of the upper handle 31 presses the clamping jaws 421a tightly, further preventing the connector 411 from being dislodged between the two clamping jaws 421a. The outer end of the clamping jaw 421a is provided with a second guide surface 421d for the lower end of the upper handle rod 31 to slide. The second guide surface 421d gradually protrudes outward from the outer wall of the lower handle rod 32 along the insertion direction of the connecting head 411. The second guide surface 421d is used to guide the upper handle rod 31 to slide to squeeze the clamping jaw 421a. The avoidance portion 421g is provided on the second guide surface 421d.

Figure 3 The first clamping portion 511 and the second clamping portion 512 are hinged to the lower push rod 42 through the shaft hole structure. Figure 4 The portions of the first clamping portion 511 and the second clamping portion 512 shown as being connected to the lower push rod 42 are made of a bendable material, allowing the first clamping portion 511 and the second clamping portion 512 to move in opposite directions or relative to each other through the bending properties between the materials. In addition, in the present application, the clamping structure includes a clamping member connected to the lower end of the lower push rod 42, namely the first clamping portion 511 and the second clamping portion 512, and a locking portion provided at the bottom of the lower handle rod 32, namely a slide groove 323 in which the first clamping portion 511 and the second clamping portion 512 slide. In some examples, a sliding pin 52 is provided on each of the first clamping portion 511 and the second clamping portion 512, and the sliding pin 52 slides in the slide groove 323 to place the clamping structure in a locked position or an unlocked position. Figure 9 An example is shown in which the sliding groove 323 is provided on the inner wall of the lower handle rod 32 . Figure 10 An example is shown in which the slide groove 323 is provided on the clamping cap 53 , wherein the clamping cap 53 is detachably connected to the bottom of the lower handle rod 32 for easy replacement.

[0054] When the cleaning brush is in use and the brush head 10 needs to be clamped, the operation key 70 is pressed. The operation key 70 drives the upper push rod 41 to move toward the top end of the upper handle rod 31 under the cooperation of the first mating surface 701 and the second mating surface 414 on the upper push rod 41, and compresses the reset member 60. The upper push rod 41 drives the lower push rod 42 to move toward the top end of the upper handle rod 31 under the connection between the connecting head 411 and the first clamping member 421. At this time, the sliding pin 52 provided on the first clamping portion 511 and the second clamping portion 522 slides in the sliding groove 323 in the direction away from the bottom of the lower handle rod 32, and the bayonet formed between the two clamping portions is on the sliding pin 5 2 and the slide groove 323, gradually increases until the clamping structure reaches the unlocked position. At this time, the protruding connector on the brush head 10 is inserted into the bayonet. After releasing the operation key 70, the upper push rod 41 moves toward the direction close to the lower handle rod 32 under the action of the reset member 60. The movement of the push rod drives the clamping member to slide toward the bottom end of the lower handle rod 32. The bayonet formed between the two clamping parts gradually decreases under the cooperation of the slide groove 323 and the sliding pin 52 until the clamping structure reaches the locked position and is maintained in the locked position by the reset member 60, clamping the connector on the brush head 10. At this time, the toilet can be cleaned with the brush head 10. After cleaning, the operation key 70 can be pressed again to drive the clamping structure to move to the unlocked position to release the clamping of the current brush head 10.
