Description

Technical Field

[0001] The invention relates to a multifunctional pulling head. Background Art

[0002] At present, the multi-function switching structures on the market mostly adopt two methods. The first is rotation switching. This type of structure cannot allow the product to automatically reset to the default water splash every time the water is turned off, which brings inconvenience to consumers. Moreover, when there are more than three water splashes, because it is a rotating switching mode, when you need to switch to the previous water splash, you need a cycle to switch successfully. At this time, if the consumer presses too fast, it is easy to miss the desired water splash again, which brings a bad experience to consumers. The second is multiple switch button switching. This type of structure has many buttons, limited appearance and is inconvenient to hold. Consumers need to be taught how to use it. The structure is complex and has many parts, and the cost is high.

[0030] Referring to the drawings of the specification, a multifunctional pull-out head includes a water channel body 10 and a water diversion plate 20. The water channel body is mainly used for passing water, and then the water flows out from different water inlets and water diversion channels of the water outlet assembly through water diversion. The water diversion channel of the water outlet assembly is basically the same as the existing technology, which is not the technology protected by the present invention and is not elaborated in detail here; it also includes a rotating drum 30 that can cooperate with the water channel body, and the rotating drum can move and rotate axially relative to the water channel body. The rotating drum can keep rotating synchronously with the water diversion plate; the rotating drum can rotate relative to the water channel body, and the water flow in the water channel body can impact the rotating drum, so that the rotating drum moves in the first axial direction A relative to the water channel body; the rotating drum is also provided with The reset spring 31 also includes a guide surface 12. A guide block 32 that can cooperate with the guide surface is arranged on the rotating drum. When there is no water flow in the water channel body, the reset spring can drive the rotating drum to move in the second axial direction B, and under the action of the guide block and the guide surface, the rotating drum can always return to its initial position with the water channel body; the first axial direction is opposite to the second axial direction, and the initial position is the state where the guide block is located at the bottom of the guide surface. At the same time, this is also the default state of the pull-out head. Every time the water is turned on, there will be splashes in this state, because the rotating drum will move in the second axial direction when the water is turned off, and may also rotate while moving, so that the guide block can always return to the position at the bottom of the guide surface.

[0031] Preferably, an inlet pipe 11 is provided in the water channel body, one end of the rotating drum is sleeved on the outer circumference of the inlet pipe, and a guide surface 12 is provided at the water outlet end of the inlet pipe, which is arranged axially. A guide block 32 is provided in the rotating drum, and the guide block can make the rotating drum move and rotate axially along the guide surface until the guide block cooperates with the bottom of the guide surface, so that the rotating drum returns to the initial state relative to the water channel body.

[0032] Furthermore, a connecting block 33 is provided inside one end of the rotating drum, and water flow can impact the connecting block to drive the rotating drum to perform a first axial movement; a water channel 34 is formed between the connecting block and the inner circumferential wall of the rotating drum, and a first sealing ring C1 is provided between the rotating drum and the inner circumferential wall of the water channel body, so that the water flow of the water inlet pipe flows through the water channel to the inside of the other end of the rotating drum. In use, a guide block can be provided at the water channel.

[0033] Furthermore, the water diversion plate is provided with a water diversion rod 21 that can rotate synchronously, and the water diversion rod can be inserted into the other end of the rotating drum. A second sealing ring C2 is provided between the other end of the rotating drum and the outer periphery of the water diversion rod, so that the unity of the overall water flow can be ensured and water leakage will not occur. The inner circumferential wall of the other end of the rotating drum is provided with ribs 35, and the outer periphery of the water diversion rod is provided with grooves 22 that can cooperate with the ribs. The axial movement of the rotating drum will not affect the cooperation between the ribs and the grooves. In this way, the rotating drum, the water diversion rod and the water diversion plate can be ensured to rotate synchronously. The water diversion rod is provided with a water outlet 23 that can communicate with the other end of the rotating drum.

[0034] Preferably, a water outlet component 40 is also included, which mainly includes a water outlet panel. The water outlet panel has multiple groups of water outlet holes, each group of water outlet holes corresponds to different water splashes, and different water diversion channels and water inlets are also correspondingly arranged. A water diversion cavity 88 is formed between the water outlet component and the water channel body, one end of the water diversion rod and the water diversion plate are located in the water diversion cavity, and at the same time, one end of the water diversion rod can be inserted into the hole of the water outlet component to keep the water diversion plate tightly matched with the sealing gasket. Referring to the accompanying drawings, the water diversion plate is not at the axial end of the water diversion rod, and one end of the water diversion rod is provided with a water outlet 24 that can be connected to the water outlet, and the water flow can flow to the water diversion cavity through the water outlet and the water outlet, and the water diversion plate is provided with a water diversion port 25. A plurality of water inlets 41 that can be connected to the water diversion port are arranged on the rear end surface of the water outlet component, and a sealing gasket C3 is arranged between the rear end surface of the water outlet component and the water diversion plate, so that each water inlet corresponds to a water splash, and water leakage will not occur.

[0035] Furthermore, it also includes a housing 50, the water outlet assembly and the waterway body are arranged in the housing, the reset spring is located between the waterway body and the other end of the drum, and when in use, the water separation plate and the water outlet assembly can be tightly matched by water pressure. Similarly, if there are some places where the water pressure is reduced, a compression spring 26 can be arranged between the waterway body and the water separation plate, and the compression spring can be combined with the water pressure to make the water separation plate and the water outlet assembly fit tightly.

[0036] In one use of the present invention, the outer circumference of the rotating drum is sequentially provided with a first ratchet group 36 and a second ratchet group 37 along its axis, the driving directions of the first ratchet group and the second ratchet group are opposite, and the first button 61 and the second button 62 are further included. When water flows through the water channel body, the first button can cooperate with the first ratchet group to drive the rotating drum to rotate, and the second button can cooperate with the second ratchet group to drive the rotating drum to rotate. The directions of rotation of the rotating drum adjusted by the first button and the second button are opposite. It can also be said that when the water is cut off, the two buttons cannot drive the rotating drum to rotate.

[0037] Furthermore, it also includes a first pawl 63 and a second pawl 64. The first button can drive the first pawl to drive the drum to rotate, and the second button can drive the second pawl to drive the drum to rotate. The movement of the drum along the first axial direction and the second axial direction is not interfered by the first pawl and the second pawl. It can also be said that when not pressed, the two pawls and the two ratchet groups are separated, and they will only cooperate when pressed. The first pawl and the second pawl include an elastic sheet 60, one end of which is connected to the waterway body, and can be locked on the waterway body with reference to the attached drawings, and the other end has a cylinder 65, which is guided and matched with the arc surface 39 on the waterway body; when the first button and the second button are pressed, the other end of the elastic sheet can be matched and connected with the first ratchet group and the second ratchet group; when the first button and the second button are not pressed, the other end of the elastic sheet can be separated from the first ratchet group and the second ratchet group. When water is flowing through the water channel body, the first pawl radially overlaps with the first ratchet group, and the second pawl radially overlaps with the second ratchet group. In other words, when the button is pressed, the pawl can cooperate with the ratchet group; when water is not flowing through the water channel body, the first pawl can be radially offset from the first ratchet group, and the second pawl can be radially offset from the second ratchet group. In other words, when water is not flowing, the two pawls cannot cooperate with the ratchet group by pressing the button, and the drum cannot be driven to rotate by the button.

[0038] More specifically, the present invention is as follows: the multifunctional pull-out head is provided with a rotating drum in the water channel body, and the rotating drum can rotate and move axially at one end, and a reset spring and a water-dividing rod are provided on the side of the rotating drum close to the water-dividing chamber. When the water is turned on, the thrust of the water pressure on the rotating drum is greater than the elastic force of the reset spring. The rotating drum can move along the waterway direction under the action of the water pressure, and can be limited by the set step surface 38. At this time, the two pawls and the two ratchet groups are radially aligned. At this time, the rotating drum can rotate under the drive of the button and drive the water-dividing rod to switch the waterway; when the water is turned off, under the action of the reset spring, the rotating drum can move in the reverse direction of the waterway to reset, and at the same time drive the water-dividing plate and the water-dividing rod to rotate synchronously and return to the initial state. By using the rotating drum, the water pressure is cleverly used to automatically unlock the rotating drum, so that the rotating drum can rotate in the boiling water state, reducing the need for consumers to unlock the action and simplifying the structure. The inner circumference of the rotating drum near the water diversion chamber is provided with ribs that cooperate with the grooves on the water diversion rod, so that the rotating drum keeps cooperating with the water diversion rod when moving, and the rotation of the rotating drum can drive the water diversion rod and the water diversion plate to rotate synchronously. There is a guide block on the other side of the rotating drum near the water inlet end, which can be a spherical convex point. There is a guide surface on the waterway body. When the water is turned on, the rotating drum is displaced due to water pressure, and the convex point is separated from the guide surface. There can be multiple guide surfaces, or they can be V-shaped grooves distributed in an annular manner. The guide surface is set on the side of the V-shaped groove. The convex point is located at the bottom 13 of the V-shaped groove after resetting, so that the rotating drum will not interfere with the waterway when rotating and switching. When the water is turned off, the reset spring pushes the rotating drum to reset and displace, and the convex point slides along the guide surface to the lowest point, driving the rotating drum to rotate to the reset state. The use of the rotating drum reset structure has greater advantages than the ordinary use of torsion springs to drive the rotation reset. The product can be switched in an unlimited number of cycles, such as "1-2-3-4-5-1-2...", and there will be no switching restrictions. At least one set of ratchet and pawl structures is provided. Pressing the button drives the pawl to move. The pawl pushes the ratchet group to drive the drum to rotate. The pawl relies on its own elasticity or spring to reset and release, and enters the next pressing preparation, so that each time the button is pressed, the drum can be driven to rotate once, realizing a water splash switch. Setting a set of ratchet and pawl structures can realize one-way cycle switching, and setting two sets of ratchet and pawl structures in opposite directions can realize two-way cycle switching, so that the previous water splash can be quickly switched back. After the water passes through the middle of the water-dividing rod, the present invention ensures that the water impacts on the water-dividing plate and then flows to the surroundings of the water-dividing chamber. In cooperation with the compression spring, the water pressure can further make the water-dividing rod press against the sealing gasket when the water is turned on, ensuring that the water splash function will not leak water; when the water is turned off, the pressing force of the water-dividing rod on the water-dividing sealing gasket is unloaded, so that the friction between the water-dividing rod and the water-dividing sealing gasket is reduced when the water is turned off. This design makes the elastic force required for the return spring of the rotating drum smaller, so that under lower water pressure, the thrust generated by the water pressure can be greater than the spring elastic force, pushing the rotating drum to move and unlock.

[0039] In the present invention, after water passes through the middle of the water-dividing rod, it is ensured that the water impacts the water-dividing plate and then flows to the surroundings. The water-dividing rod is pressed against the sealing gasket when the water is turned on by relying on the water pressure, so as to ensure that the water splash function does not leak water; when the water is turned off, the pressing force of the water-dividing rod on the sealing gasket is relieved, so that the friction between the water-dividing rod and the water-dividing sealing gasket is reduced when the water is turned off. This design makes the elastic force required for the reset spring of the rotating drum smaller, so that under lower water pressure, the thrust formed by the water pressure can be greater than the spring elastic force, pushing the rotating drum to perform axial displacement, thereby achieving unlocking.

[0040] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field.
