The lower end of the first flow channel 204 is a first water inlet, the lower end of the second flow channel 205 is a second water inlet, and the first water inlet and the second water inlet are both communicated with the water diversion cavity 206. In this embodiment, the first water inlet is disposed rearward, and the second water inlet is disposed frontward.

After the housing 203 is fixedly connected with the lower end of the shower head body, the opening structure of the lower end of the first channel 130 is communicated with the first water outlet 201 of the first flow channel 204, and the opening structure of the lower end of the second channel 140 is communicated with the second water outlet 202 of the second flow channel 205. Thus, a portion of the water in the diversion chamber 206 can flow through the first flow passage 204 and the first channel 130 to the first outlet plate, and another portion of the water can flow through the second flow passage 205 and the second channel 140 to the second outlet plate.

The piston block 250 is provided in the water distribution chamber 206 of the housing 203, and the outer peripheral surface of the piston block 250 contacts the inner peripheral surface of the water distribution chamber 206, so that the piston block 250 can divide the water distribution chamber 206 into two parts. The piston block 250 is connected with the housing 203 in a sliding manner back and forth, so that the piston block 250 can move forwards or backwards along the water distribution cavity 206. Specifically, the piston block 250 is cylindrical, and thus the water diversion chamber 206 is a cylindrical chamber.

In this embodiment, in order to reduce the contact area between the piston block 250 and the water diversion cavity 206, the piston block 250 is sleeved with a sealing ring, and the sealing ring may be made of silicone or rubber. Specifically, the outer circumferential surface of the piston block 250 is provided with an annular groove, the sealing ring is arranged in the groove, the outer circumferential surface of the sealing ring is in contact with the inner circumferential surface of the water diversion cavity 206, and the sealing ring can exert a good sealing effect. The sealing ring is arranged to reduce the motion resistance of the piston block 250 from the wall surface of the water diversion cavity 206. The piston block 250 may be made of metal, such as stainless steel, and is not particularly limited thereto.

The piston block 250 is hollow to form a pipeline structure 251, and the piston block 250 is provided with an inlet and an outlet, and the inlet and the outlet are both communicated with the pipeline structure 251. Specifically, the front end surface of the piston block 250 is provided with an outlet, and the rear end surface of the piston block 250 is also provided with an outlet. The lower surface of the piston block 250 is provided with an inlet. It will be appreciated that the number of outlets on the front end face of the piston block 250 is not limited to one, and of course, the number of outlets on the rear end face of the piston block 250 is not limited to one. The outlet and inlet may both be circular openings.

In addition, sealing rings may be provided at both front and rear sides of the inlet, and the sealing rings are fitted over the outer circumferential surface of the piston block 250.

During the forward or backward movement of the piston block 250 along the water distribution chamber 206, the inlet of the piston block 250 is always in communication with the water inlet 220 of the housing 203, and thus, water flowing in through the water inlet 220 can flow into the pipe structure 251.

The communication port between the first flow passage 204 and the water distribution chamber 206 (i.e., the first water inlet) is offset from the outlet of the piston block 250, and the communication port between the second flow passage 205 and the water distribution chamber 206 (i.e., the second water inlet) is offset from the outlet of the piston block 250. Specifically, the first and second water inlets are disposed opposite to each other in the front-rear direction, and are located below the outlet of the piston block 250. The outlet of the piston block 250 may be located at a middle position or an upper position in the up-down direction of the piston block 250.

The front end surface and the rear end surface of the piston block 250 are both flat surfaces, and the inner front wall surface and the inner rear wall surface of the water diversion cavity 206 are both flat surfaces.

The front end face and the rear end face of the piston block 250 may be provided with seal grooves, rubber rings are arranged in the seal grooves, and the rubber rings are coaxially arranged with the outlet of the piston block 250. When the end face of the piston block 250 contacts the inner wall surface of the water distribution chamber 206, the rubber ring is deformed by force, and a good sealing effect is achieved.

As shown in fig. 2 and 5, when the piston block 250 moves forward to a position, the front end surface of the piston block 250 can abut against the inner front wall surface of the water diversion cavity 206, and at this time, the outlet located at the front side of the piston block 250 is blocked by the inner front wall surface of the water diversion cavity 206, so that the outlet is blocked, and then, water in the pipeline structure 251 can only flow into the water diversion cavity 206 located at the rear side of the piston block 250 from the outlet located at the rear side of the piston block 250, and then flows to the second water outlet tray through the second flow passage 205 and the second passage 140, so as to realize the water outlet function of the second water outlet tray.

As shown in fig. 2 and 4, when the piston block 250 moves backward to a proper position, the rear end surface of the piston block 250 can contact with the inner rear wall surface of the water diversion cavity 206, and at this time, the outlet located at the rear side of the piston block 250 is blocked by the inner rear wall surface of the water diversion cavity 206, so that the outlet is closed, and therefore, water in the pipeline structure 251 can only flow into the water diversion cavity 206 located at the front side of the piston block 250 from the outlet located at the front side of the piston block 250, and then flows to the first water outlet tray through the first flow passage 204 and the first channel 130, and the water outlet function of the first water outlet tray is realized.

As shown in fig. 2 and 3, when both front and rear end surfaces of the piston block 250 are not in contact with the front and rear inner wall surfaces of the water diversion chamber 206, outlets at both front and rear ends of the piston block 250 are in an open state and are both communicated with the water diversion chamber 206, so that a part of water in the pipeline structure 251 can flow to the water diversion chamber 206 at the front side of the piston block 250 through the outlet at the front side of the piston block 250, then flow into the first water outlet tray through the first flow passage 204 and the first passage 130, and at the same time, another part of water in the pipeline structure 251 can flow to the water diversion chamber 206 at the rear side of the piston block 250 through the outlet at the rear side of the piston block 250, and then flow to the second water outlet tray through the second flow passage 205 and the second passage 140, and finally realize the function of simultaneously discharging water from the first water outlet tray and the second water outlet tray.

Of course, when the first and second water outlet discs are simultaneously discharging water, the piston block 250 can be controlled to move forward or backward to adjust the communication area between the water inlet 220 and the inlet of the piston block 250, so as to adjust the water flow rate flowing into the pipeline structure 251.

The front end surface of the piston block 250 is provided with a push rod 230, and the rear end surface of the piston block 250 is also provided with the push rod 230. Both ends of each push rod 230 are extended in the front and rear direction of the piston block 250, and the push rod 230 penetrates the housing 203 such that the end of the push rod 230 is exposed to allow a user to apply force to the end of the push rod 230, thereby moving the piston block 250 in the front and rear direction of the water distribution chamber 206.

In the present embodiment, the push rod 230 is a round rod. The push rod 230 and the piston block 250 can be connected and fixed through an integral molding process. The push rod 230 is coaxially disposed with the piston block 250, and then the pipe structure 251 needs to be disposed to avoid the push rod 230. In the piston block 250, a pipe structure 251 may be provided at both left and right sides of the push rod 230.

A seal is provided between the push rod 230 and the housing 203. The sealing element is a sealing rubber ring. The number of seals is not limited to one. It will be appreciated that the sealing member is provided to prevent the water in the water diversion chamber 206 from leaking through the gap between the push rod 230 and the housing 203 during the forward and backward movement of the push rod 230.

In order to facilitate installation of the piston block 250 in the water diversion cavity 206, the housing 203 may be composed of a left part and a right part, the left part and the right part may be connected and fixed by welding or bolts, and a sealing rubber ring is disposed between the left part and the right part to enhance the waterproof sealing effect.

In the present embodiment, two first flow passages 204 and two second flow passages 205 are provided. Taking the first flow passages 204 as an example, one of the first flow passages 204 is located on the left side of the push rod 230, and the other first flow passage 204 is located on the right side of the push rod 230. Therefore, the first flow passage 204 and the second flow passage 205 can avoid the connection between the push rod 230 and the housing 203.

It can be understood that the shower head provided by the embodiment adopts the above-mentioned unique structure, not only can realize the switching of three water outlet modes, but also the user can carry out the pushing operation of the front and back direction to the push rod 230 by one hand, thereby reducing the operation difficulty.

In some embodiments, the push rod 230 is provided with a pressing block 210. Specifically, the pressing block 210 is located at the end of the push rod 230 that is distal from the diversion cavity 206. Specifically, taking the push rod 230 located at the front side of the piston block 250 as an example, the pressing block 210 is located at the front end of the push rod 230; taking the push rod 230 located at the rear side of the piston block 250 as an example, the pressing block 210 is located at the rear end of the push rod 230. The pressing block 210 and the pushing rod 230 may be integrally formed, screwed, or screwed, and are not limited in this respect.

The pressing block 210 may be made of metal or plastic, and is not particularly limited thereto. The cross-sectional shape of the pressing block 210 is circular. The pressing block 210 has a diameter greater than that of the push rod 230. According to the setting of pressing piece 210, can provide better application of force point for the user, can increase according to the area of pressing piece 210 and user's contact, reduce push rod 230 and act on user's pressure to improve and use the comfort.

When the water outlet function of the first water outlet tray or the water outlet function of the second water outlet tray is realized, the fingers of the user can always apply force to the pressing block 210, so that the end surface of the piston block 250 is always in contact with the inner wall surface of the water distribution cavity 206.

In some embodiments, the effluent regulating device 200 further comprises a magnet 240.

The front side of the water diversion cavity 206 is provided with a magnet 240, and the rear side of the water diversion cavity 206 is also provided with a magnet 240. Taking the magnet 240 positioned in front of the water diversion cavity 206 as an example, the magnet 240 is arranged between the water diversion cavity 206 and the pressing block 210 positioned in front of the water diversion cavity 206; taking the magnet 240 located at the rear side of the water diversion cavity 206 as an example, the magnet 240 is disposed between the water diversion cavity 206 and the pressing block 210 located at the rear side of the water diversion cavity 206. The magnet 240 is fixedly connected to the housing 203, such as by a screw connection or a snap connection.

The magnet 240 may be a bar magnet, a U-shaped magnet, or a ring magnet. If a bar magnet is used, the bar magnet is fixed to the housing 203 so as to extend vertically in order to reduce the size of the housing 203 in the front-rear direction. If the ring magnet is adopted, the ring magnet and the push rod 230 are coaxially arranged, and a certain gap exists between the ring magnet and the push rod 230 so as to prevent the push rod 230 from being subjected to the friction action of the ring magnet. The front end and the rear end of the circular ring magnet are magnetic poles with opposite magnetism.

The magnet 240 can magnetically attract the pressing block 210. Specifically, the pressing block 210 may be an iron block, or an iron block or a permanent magnet may be provided on the pressing block 210.

It can be understood that, since the magnets 240 are disposed at the front side and the rear side of the water diversion cavity 206, and the magnetic force between the magnets 240 and the pressing block 210 is related to the distance between them, when the piston block 250 contacts with one side wall surface of the water diversion cavity 206, the distance between the pressing block 210 and the magnets 240 at the other side of the water diversion cavity 206 is greatly reduced, so that the pressing block 210 is attracted by stronger magnetic force, and the piston block 250 is always kept in contact with the water diversion cavity 206, so that the user does not need to press the pressing block 210 at any time.

For example, when the plunger block 250 moves forward, the distance between the magnet 240 located at the front side of the plunger block 250 and the pressing block 210 increases, the magnetic force decreases, the distance between the magnet 240 located at the rear side of the plunger block 250 and the pressing block 210 decreases, and the magnetic force increases.

It is understood that the pressing block 210 located at the rear side of the plunger block 250 may contact the magnet 240 after the plunger block 250 is advanced to a position; after the piston block 250 is moved backward, the pressing block 210 located at the front side of the piston block 250 may contact the magnet 240; at this time, the magnet 240 can perform a limit function so that the user knows that the plunger piece 250 is moved in place.

In some embodiments, the front side of the housing 203 is recessed rearward to form a receiving groove, and the rear side of the housing 203 is recessed forward to form a receiving groove. The magnet 240 is disposed in the receiving recess. The receiving groove may be a cylindrical groove. The outer diameter of the pressing block 210 is appropriate to the inner diameter of the receiving groove, but the outer circumferential surface of the pressing block 210 does not contact the inner circumferential surface of the receiving groove.

It can be understood that the arrangement of the accommodating groove can provide an installation space for the magnet 240, and the magnet 240 is prevented from being completely exposed, so that the attractiveness of the shower head is improved.

In some embodiments, the magnet 240 is replaced with a spring. The number of the springs may be two, and the springs are provided in one-to-one correspondence with the two push rods 230. The two ends of the spring extend forwards and backwards, and the spring can stretch and retract forwards and backwards. One end of the spring is fixedly connected with the housing 203, the other end of the spring is fixedly connected with the push rod 230, the connection mode can be a welding mode or a clamping mode, and particularly, the other end of the spring is connected with the pressing block 210.

It can be understood that, in the case that the springs at the front and rear sides of the piston block 250 exert elastic forces, the elastic forces applied to the push rods 230 at the front and rear sides of the piston block 250 are balanced with each other, so that the piston block 250 can be automatically reset, and the piston block 250 is located at the middle position of the water diversion chamber 206 in the front and rear direction. After piston block 250 is automatically reset, a front surface of pressing block 210 located at a front side of piston block 250 is flush with a front surface of housing 203, and a rear surface of pressing block 210 located at a rear side of piston block 250 is flush with a rear surface of housing 203. Of course, the pressing block 210 may also protrude from the receiving groove.

Under the condition of arranging the spring, when the water outlet function of the first water outlet tray or the water outlet function of the second water outlet tray is realized, the pressing block 210 needs to be pressed by the fingers of the user all the time to prevent the piston block 250 from automatically resetting, so that the water outlet mode is automatically switched to the first water outlet tray and the second water outlet tray to simultaneously discharge water.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions without departing from the spirit of the invention as set forth in the claims appended hereto.
