[0002] Showers are usually equipped with various water control mechanisms to control various water sprays or water flow rates. Traditional water control mechanisms on showers generally include button-type water control mechanisms and knob-type water control mechanisms, which usually have only a single control function. For example, a button-type water control mechanism can only control the corresponding function by pressing the button, and it is not possible to control the function by rotating the button; while a knob-type water control mechanism can only control the corresponding function by rotating the knob, and it is not possible to control the function by pressing the knob. If the water control mechanism needs to be both press-controlled and rotate-controlled, it is necessary to set a button and a knob separately, which is more complicated in structure, occupies a large space, and is inconvenient to operate.

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] Please refer to Figures 1 to 11 In one embodiment of the present invention, a water channel control mechanism 100 with an integrated control switch includes a main body 10 of the water channel control mechanism, a press-type water channel switching component 20, a flow control component 30, and a control switch 40. This embodiment is described in detail by taking the water channel control mechanism used on a shower 200 as an example. The water outlet mode of the shower 200 can be controlled by pressing the control switch 40 of the water channel control mechanism, and the water outlet flow of the shower 200 can also be controlled by rotating the control switch 40 of the water channel control mechanism.

[0048] The main body 10 of the water channel control mechanism has a water inlet channel 11 and at least two water outlet channels. In this embodiment, two water outlet channels are provided, namely a first water outlet channel 12 and a second water outlet channel 13. The water outlet mode of the first water outlet channel 12 is different from the water outlet mode of the second water outlet channel 13. For example, the first water outlet channel 12 flows out shower water, and the second water outlet channel 13 flows out sheet water, etc., but the present invention is not limited to this.

[0049] The push-type water circuit switching component 20 is movably arranged on the main body 10. When the push-type water circuit switching component 20 is pressed, the water inlet channel 11 is controlled to switch to be connected or disconnected with each water outlet channel. When the push-type water circuit switching component 20 is pressed, the water inlet channel 11 is controlled to switch to be connected or disconnected with each water outlet channel, wherein "connected" may mean that the water inlet channel is connected to one of the water outlet channels, or is connected to multiple water outlet channels, or is connected to all water outlet channels at the same time; wherein "disconnected" may mean that the water inlet channel 11 is disconnected from one of the water outlet channels, or is disconnected from multiple water outlet channels, or is disconnected from all water outlet channels at the same time. Specifically, in this embodiment, the water channel switching assembly 20 has four positions. In the first position, the water inlet channel 11 is connected to the first water outlet channel 12 and is cut off from the second water outlet channel 13; in the second position, the water inlet channel 11 is connected to both the first water outlet channel 12 and the second water outlet channel 13; in the third position, the water inlet channel 11 is cut off from the first water outlet channel 12 and is connected to the second water outlet channel 13; in the fourth position, the water inlet channel 11 is cut off from both the first water outlet channel 12 and the second water outlet channel 13. The water channel switching assembly 20 rotates and switches between the above four positions, and its specific switching structure will be described in detail below.

[0050] The flow control assembly 30 is rotatably disposed on the main body 10 , and controls the flow cross-sectional area of ​​the water inlet channel 11 when the flow control assembly 30 rotates.

[0051] The control switch 40 is rotatably and slidably mounted on the main body 10. When the control switch 40 is pressed, the control switch 40 drives the push-type waterway switching assembly 20 to perform a switching action; when the control switch 40 is rotated, the control switch 40 drives the flow control assembly 30 to rotate.

[0052] The projections of the push-type water circuit switching component 20 and the flow control component 30 in the sliding direction of the control switch 40 do not overlap or only partially overlap. In this embodiment, the push-type water circuit switching component 20 and the flow control component 30 are arranged side by side along a direction perpendicular to the sliding direction of the control switch 40.

[0053] Specifically, in this embodiment, a water diversion chamber 14 connected to the water inlet channel 11 is formed on the main body 10, and at least two flow holes connected to the water outlet channels are formed in the water diversion chamber 14, and the push-type water channel switching component 20 cooperates with the flow holes to open or close the flow holes. In this embodiment, the flow hole connected to the first water outlet channel 12 is the first flow hole 1421, and the flow hole connected to the second water outlet channel 13 is the second flow hole 1422. The first flow hole 1421 and the second flow hole 1422 are both arranged on the bottom wall 142 of the water diversion chamber 14 described below.

[0054] In this embodiment, the push-type waterway switching assembly 20 adopts a push-type switching structure similar to that used on a ballpoint pen commonly used in the art, which includes a switching member 21, a pressing member 22, and a first reset elastic member 23. A ratchet 211 is provided on the switching member 21, and a ratchet 221 is provided on the pressing member 22 to cooperate with the ratchet 211. When the control switch 40 drives the pressing member 22 to slide relative to the main body 10, the switching member 21 is rotated in one direction by a preset angle under the action of the ratchet 211 and the ratchet 221, and the switching member 21 switches to open the flow hole when rotating. In this embodiment, under the action of the ratchet 211 and the ratchet 221, the switching member 21 rotates 90° each time, that is, the two adjacent positions between the first position, the second position, the third position and the fourth position of the switching member 21 are 90° apart. Pressing the control switch 40 four times will drive the switching member 21 to rotate one circle. Here, since the push-type water channel switching component 20 adopts a push-type switching structure similar to that used on a ballpoint pen commonly used in the art, its specific working principle will not be described in detail here.

[0055] Specifically, in the present embodiment, an opening 141 is formed at one end of the water-dividing chamber 14, and a bottom wall 142 of the water-dividing chamber 14 is formed at the other end. The push-type water circuit switching assembly 20 is installed in the water-dividing chamber 14 via the opening 141. It also includes a buckle cover 15 connected to the opening 141 with a sealing cover. The switching member 21 is a sheet-like structure and cooperates with the bottom wall 142 of the water-dividing chamber 14 to rotate relative to each other. The bottom wall 142 of the water-dividing chamber 14 extends outward with a sleeve 16 connected to the water-dividing chamber 14, the ratchet 211 on the switching member 21 and the ratchet 221 on the top pressure member 22 cooperate in the sleeve 16, one end of the top pressure member 22 extends outward from the sleeve 16 and cooperates with the control switch 40, and the top pressure member 22 cooperates with the inner wall of the sleeve 16 in a dynamic seal and circumferential limit. A rotating shaft 17 is further provided in the water-dividing chamber 14 , and the switching member 21 rotates around the rotating shaft 17 . The first resetting elastic member 23 is a compression spring and is sleeved outside the rotating shaft 17 . The first resetting elastic member 23 is elastically pushed between the switching member 21 and the buckle cover 15 .

[0056] In this embodiment, a flow regulating chamber 18 connected to the water inlet channel 11 is also formed on the main body 10, and the flow control component 30 includes a flow control valve core 31, the flow control valve core 31 has a regulating part 311 extending into the flow regulating chamber 18 and a driving part 312 located outside the flow regulating chamber 18, and the regulating part 311 is provided with an regulating hole 3111 extending radially therethrough. When the regulating part 311 rotates in the flow regulating chamber 18, the flow cross-sectional area of ​​the flow regulating chamber 18 is changed by changing the opening size of the regulating hole 3111, thereby changing the flow cross-sectional area of ​​the water inlet channel 11.

[0057] Specifically, in this embodiment, the control switch 40 includes a switch body 41 and a rotary sleeve 42, wherein the rotary sleeve 42 is sleeved on the outer periphery of the switch body 41 and cooperates with the circumferential limit of the switch body 41. The switch body 41 is provided with a first tooth portion 411, and the driving portion 312 of the flow control valve core 31 is provided with a second tooth portion 3121 meshed with the first tooth portion 411. When the control switch 40 rotates, the meshing of the first tooth portion 411 and the second tooth portion 3121 drives the flow control valve core 31 to rotate, thereby changing the flow cross-sectional area of ​​the flow regulating chamber 18. The outer wall of the rotary sleeve 42 is provided with an anti-slip rib 421, thereby facilitating the rotation operation of the control switch 40.

[0058] In this embodiment, the flow regulating chamber 18 is located upstream of the water diversion chamber 14 .

[0059] In this embodiment, a limiting structure 50 for directly or indirectly limiting the rotation of the control switch 40 is also included. The limiting structure 50 controls the control switch 40 to rotate within a predetermined range. Specifically, the limiting structure 50 is an arc-shaped limiting hole 50 provided on the fixing member 240 described below. A second reset elastic member 60 for resetting the control switch 40 after being pressed is also provided between the control switch 40 and the body 10. The second reset elastic member 60 is specifically a compression spring, and can also be a spring sheet, etc. A buckle foot 412 is provided on the switch body 41 of the control switch 40. The buckle foot 412 is buckled with the fixing member 240 so that the control switch 40 will not be separated from the body 10 under the action of the second reset elastic member 60. In addition, the buckle foot 412 can slide in the arc-shaped limiting hole 50 along the circumferential direction. The buckle foot 412 is limited by the two ends of the arc-shaped limiting hole 50 in the circumferential direction, so that the arc-shaped limiting hole 50 directly limits the rotation of the control switch 40. Alternatively, the limit structure 50 can also be used to rotationally limit the flow control valve core 31. Since the control switch 40 and the flow control valve core 31 are rotationally linked, the limit structure 50 that directly limits the flow control valve core 31 will indirectly limit the control switch 40.

[0060] In this embodiment, a positioning structure 70 is also included for directly or indirectly rotating and positioning the control switch 40. The positioning structure 70 controls the control switch 40 to be positioned at the adjustment position. In this embodiment, the positioning structure 70 indirectly rotates and positions the control switch 40. Specifically, a plurality of positioning grooves 71 are provided on the body 10, and an elastic buckle 72 is provided on the flow control valve core 31. When the flow control valve core 31 rotates in the flow adjustment chamber 18, the elastic buckle 72 on the flow control valve core 31 is sequentially engaged with each positioning groove 71, so that the flow control valve core 31 can be positioned at the adjustment position. Since the control switch 40 and the flow control valve core 31 are rotationally linked, the positioning structure 70 that directly rotates and positions the flow control valve core 31 will indirectly rotate and position the control switch 40. Alternatively, the elastic buckle 72 can also be provided on the control switch 40, so that the positioning structure 70 can directly rotate and position the control switch 40.

[0061] In this embodiment, the shower head 200 includes a handle 210 and a shower head 220 connected to each other, the water channel control mechanism 100 is arranged on the handle 210, the control switch 40 slides along the radial direction of the handle 210, and the push-type water channel switching assembly 20 and the flow control assembly 30 are arranged in parallel along the axial direction of the handle 210. In this way, the water flow control mechanism 100 occupies a small radial space of the handle 210, so that the water channel control mechanism 100 can be arranged on the handle 210 of a relatively thin shower head 200, and the user can press or rotate the control switch 40 with one hand while holding the handle 210, which is more convenient for the user to operate.

[0062] In this embodiment, the main body 10 of the water channel control mechanism is sleeved in the inner cavity of the handle 210, and a through hole 230 is opened on the side wall of the handle 210. It also includes a fixing member 240. The fixing member 240 extends into the inner cavity of the handle 210 through the through hole 230 and is detachably fixed to the main body 10 by a screw 250. The fixing member 240 limits the main body 10 in the inner cavity of the handle 210, and the control switch 40 is passed through the through hole 230.

[0063] The working process of this embodiment is briefly described as follows:

[0064] Please refer to Figure 6 and Figure 7 At this time, the switch member 21 is in the first position, the switch member 21 opens the first flow hole 1421 and closes the second flow hole 1422, so that the water inlet channel 11 is connected with the first water outlet channel 12 and is cut off from the second water outlet channel 13, and the shower head 200 realizes water discharge from the first water outlet channel 12;

[0065] When the control switch 40 is pressed once, the control switch 40 drives the pressing member 22 to slide relative to the main body 10, and under the action of the ratchet 211 and the ratchet teeth 221, the switching member 21 continues to rotate 90 degrees in one direction and switches to the second position. At this time, the switching member 21 simultaneously opens the first flow hole 1421 and the second flow hole 1422, so that the water inlet channel 11 is connected with the first water outlet channel 12 and the second water outlet channel 13 at the same time, and the shower head 200 realizes water discharge from the first water outlet channel 12 and the second water outlet channel 13 at the same time;

[0066] When the control switch 40 is pressed again, the control switch 40 drives the pressing member 22 to slide relative to the main body 10, and under the action of the ratchet 211 and the ratchet teeth 221, the switching member 21 continues to rotate 90 degrees in one direction and switches to the third position. At this time, the switching member 21 closes the first flow hole 1421 and opens the second flow hole 1422, so that the water inlet channel 11 is cut off from the first water outlet channel 12 and connected to the second water outlet channel 13, and the shower head 200 realizes water discharge from the second water outlet channel 13;

[0067] When the control switch 40 is pressed again, the control switch 40 drives the pressing member 22 to slide relative to the main body 10, and under the action of the ratchet 211 and the ratchet teeth 221, the switching member 21 continues to rotate 90° in one direction and switches to the fourth position. At this time, the switching member 21 simultaneously closes the first flow hole 1421 and the second flow hole 1422, so that the water inlet channel 11 is simultaneously cut off from the first water outlet channel 12 and the second water outlet channel 13, and the shower stops discharging water.

[0068] By repeating the above pressing action, the shower head 200 switches between the above-mentioned various water outlet modes.

[0069] Please refer to Figure 8 and Fig. 9 At this time, the opening of the regulating hole 3111 on the regulating part 311 is 0, and the flow control valve core 31 cuts off the water inlet channel 11, so that the shower head 200 stops discharging water.

[0070] exist Figure 8 and Fig. 9 In the state, the adjusting part 311 is rotated to gradually increase the opening of the adjusting hole 3111, so that the flow cross-sectional area of ​​the water inlet channel 11 is gradually increased, and the water flow rate of the shower head 200 is also increased accordingly. Please refer to Fig.10 and Fig.11 , at this time, the opening of the regulating hole 3111 is the largest. By changing the opening size of the regulating hole 3111, the flow cross-sectional area of ​​the flow regulating chamber 18 is changed, and then the flow cross-sectional area of ​​the water inlet channel 11 is changed, so that the flow regulation is very simple and convenient.

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.
