In the claims, specification and drawings of the present invention, unless explicitly defined otherwise, the term "fixedly connected" or "fixedly connected" should be construed broadly, i.e. any connection between the two without a displacement relationship or a relative rotation relationship, that is to say includes non-detachably fixedly connected, and fixedly connected by other means or elements.
Referring to fig. 1 to 4, embodiment 1 of the present invention provides a multifunctional shower head 1, which includes: the device comprises a body 10, a gland 21, a water diversion piece 22, a face cover 23, a base plate 31, a piston 32 and an elastic piece 40.
A water inlet channel 11 is arranged in the body 10.
The gland 21, the water dividing member 22 and the face cover 23 are fixedly connected with each other to form a water outlet assembly 20. The water outlet assembly 20 has a first water outlet channel and a second water outlet channel formed therein. The first water outlet channel and the second water outlet channel are communicated with the water inlet channel 11 in a switching way and are provided with common water outlet holes so as to discharge water from the common water outlet holes.
One side of the base plate 31 is fixedly provided with a turbulence part 33, and the other side of the base plate is fixedly connected with the piston 32 to form an adjusting piece 30. After assembly, the piston 32 is slidably disposed within the second water outlet channel such that the regulator 30 is slidably coupled to the water outlet assembly 20.
The elastic member 40 is a spring, and is disposed between the adjusting member 30 and the water outlet assembly 20, for resetting the adjusting member 30 when the second water outlet channel is not connected to the water inlet channel 11.
In use, the first water outlet channel and the second water outlet channel are selectively in communication, and when the second water outlet channel is flushed, the flow of water therein pushes the piston 32 to slide such that the regulating member 30 slides in a first direction between the first position and the second position; when the second water outlet channel is not filled with water, namely, the first water outlet channel is switched to be filled with water or the shower head is in a water-closing state, the acting force of the water flow is eliminated, and the spring 40 drives the regulating element 30 to reversely reset along the first direction. Wherein, in the first position, the turbulence part 33 is close to the water outlet hole, and the water flow is disturbed by the turbulence part and then discharged; in the second position, the turbulence part 33 is far away from the water outlet hole, and the water flow is not disturbed by the turbulence part to discharge water. Thus, when the adjusting member 30 is at different positions, the shower head has different water outlet effects.
According to the shower head provided by the embodiment of the invention, whether the second water outlet channel is communicated or not is switched, so that the relative position and distance between the turbulence part 33 of the regulating piece 30 and the water outlet hole are changed, and the water outlet effect of the common water outlet hole is further switched. Therefore, the shower head can realize the switching of the water outlet effect of the same water outlet hole only by switching and communicating the water inlet channel 11 to the first water outlet channel and the second water outlet channel and then utilizing the principle of hydraulic driving and elastic resetting to enable the turbulence part 33 to move and reset along the preset path, thereby being stable and reliable.
Furthermore, since the present invention uses water pressure to drive the regulator 30 within the water outlet assembly 20, it actually breaks the entire drive link formed from the user operated end to the spoiler 33 into two independently constructed portions. One part of the driving mechanism is an integral module formed by assembling the adjusting piece 30 to the water outlet assembly 20, and the other part of the driving mechanism can directly adopt the existing various switching devices, and only simple waterway switching is needed, so that the two parts can be connected in a seamless manner and form the driving link. Therefore, the whole module can be adapted to other switching modes and devices at the user operation end, so that the requirement of diversification of operation modes of the multifunctional shower in the market can be met, and the existing switching module can be used in the production and manufacture of products, thereby realizing modularized design and manufacture. In addition, the integral module is formed by only assembling the adjusting piece in the water outlet assembly and enabling a part of the adjusting piece to be positioned in the second water outlet channel, and the internal structure of the adjusting piece is not complex, so that the invention has a larger cost advantage.
Specifically, in order to achieve the above-mentioned switching, the present embodiment adopts a switching manner in which the entire water outlet assembly 20 rotates relative to the main body 10, that is, a conventional switching manner of the rotating surface cover. It can be seen that the driving and transmission members required for driving the spoiler 33 in motion are greatly reduced, the structure is simple, and further the advantages of cost and assembly are achieved. It should be understood that, in other embodiments, a manner of switching a button, a manner of switching a push button, or the like may be used instead of the manner of switching the rotating surface cover, so long as the water inlet channel 11 can be switched between the first water outlet channel and the second water outlet channel. The implementation modes of the switching are all common technical means in the field of multifunctional showers, and the invention is not limited to the common technical means.
In addition, the adjusting member 30 is driven by the water pressure of the water flow in the water outlet assembly 20, so that a user only needs to overcome the corresponding resistance of switching the first water outlet channel and the second water outlet channel during operation, the water pressure and the resistance born by the adjusting member do not need to be overcome, and the operation is light. In the existing similar shower, the adjustment piece in water is driven by means of mechanical transmission among the components, so that a user needs to overcome not only the mechanical resistance of a complex transmission mechanism, but also the water pressure action of water flow on the end face of the adjustment piece 30 during operation, thereby increasing the required operation force and being difficult to operate.
It should be noted that, in embodiment 1, the piston 32 is fixedly connected to the spoiler, so that the piston is directly driven by the water pressure to drive the spoiler 33 to slide. However, to achieve that the turbulence part 33 is close to or far from the water outlet, so as to disturb the water flow entering the water outlet, the implementation manner is not limited to sliding the turbulence part 33 relative to the water outlet. In other embodiments, the impeller in the prior art may be used instead of the piston, and the spoiler is fixedly connected with the impeller or is in transmission connection with the impeller through a speed reducing mechanism. Then, when the second water outlet channel is filled with water, the water flow pushes the impeller to rotate, and the turbulence part follows and rotates between different circumferential positions on the same horizontal plane. At one of them circumference position, the spoiler cooperates with the apopore, carries out the vortex to rivers to change out the water effect. In this embodiment, the elastic member may correspondingly employ a torsion spring.
Referring back to embodiment 1 and referring to fig. 1-7, specifically, in the water outlet assembly 20, the gland 21 and the water diversion member 22 surround to form a first switching chamber 24A and a second switching chamber 24B, the water diversion member and the face cover surround to form a first water outlet chamber 25A, and the face cover is provided with a first water outlet hole 26A corresponding to the first water outlet chamber 25A. In addition, the water diversion member 22 is further provided with a first water passing port 27A and a second water passing port 27B for respectively communicating the first switching chamber 24A and the second switching chamber 24B to the first water outlet chamber 25A.
The first switching cavity 24A, the first water outlet cavity 25A and the first water outlet hole 26A are communicated to form the first water outlet channel; the second switching chamber 24B, the first water outlet chamber 25A and the first water outlet hole 26A are communicated to form the second water outlet channel. In a specific switching process, the water inlet channel 11 is switched to be communicated with the first switching cavity 24A and the second switching cavity 24B.
The base plate 31 is slidably disposed in the first water outlet cavity 25A; the piston 32 passes through the second water passing port 27B and is assembled in the second switching cavity 24B, and forms a pressure bearing part, which is driven by water pressure when the second switching cavity is connected with water, so that the adjusting piece 30 slides along the first direction relative to the water outlet assembly 20; the turbulence part 33 is slidably disposed in the first water outlet cavity 25A, and slidably fits the first water outlet hole 26A.
In this embodiment 1, the first direction is defined as pointing from the first position to the second position, i.e., the water pressure pushes the spoiler 33 away from the first water outlet hole 26A. On this basis, the water outlet assembly 20 and the regulating member 30 are further configured to have the following specific structures.
In order to enable the piston 32 to be pushed effectively and stably by the water flow, the piston is configured to have an end face facing the base plate 31 and not in contact with the bottom of the second switching chamber 24B (the upper end face of the water dividing member 22 in this embodiment) when the regulating member 30 is in the first position. Thus, when the second switching chamber 24B is opened, the water flow applies pressure to the end surface, and the regulator 30 is slid to the second position.
The water outlet assembly 20 (the gland 21 in this embodiment) is further provided with a protruding portion at a position corresponding to the second switching chamber 24B, and a sliding groove 28 for sliding the piston is formed in the protruding portion, and the sliding groove forms a part of the second switching chamber. The peripheral wall of the piston 32 is in sealing fit with the inner wall of the chute 28, and the top of the protruding part, namely the bottom of the chute 28, is provided with an exhaust hole 29. Thus, the piston 32 is slidably disposed in the chute 28, which divides the second switching chamber 24B into a water passing portion and a non-water passing portion, and when the second switching chamber is water-passing, the non-water passing portion can be communicated with the atmosphere through the air outlet 29, so that the piston can be pushed to slide in the chute 28 without a large water pressure, and the switching is rapid. In addition, the screw on the piston 32 can be locked through the exhaust hole 29, so that the assembly is convenient.
Further, in this embodiment, one end of the spring 40 abuts against the top wall of the first water outlet chamber 25A (the lower end surface of the water dividing member 22 in this embodiment), and the other end abuts against the base plate 31. When the regulating member 30 slides from the first position to the second position, the spring 40 compresses and accumulates elastic potential energy to drive the regulating member 30 to return when the second switching chamber 24B is not filled with water. In other embodiments, the spring 40 may be disposed between the piston 32 and the gland 21.
Preferably, as can be seen from fig. 8 to 11, the base plate 31 is provided with a plurality of third water passing holes 34 penetrating therethrough, which not only reduces the weight of the adjusting member 30 so as to make it lighter and easier to push, but also accelerates the flow rate of water flowing in the first water outlet cavity 25A from the second water passing hole 27B to pass through the base plate 31 and flow to the first water outlet hole 26A, accelerates the water outlet speed after switching, and reduces the response time after switching.
Referring to fig. 13-16, after the configuration described above, when the sprinkler of the present embodiment is in operation and the second switching chamber 24B is connected with water, the adjusting member 30 slides from the first position to the second position under the action of the water pressure, and the turbulence part 33 is away from the first water outlet 26A, as shown in fig. 15-16; when the second switching cavity 24B is not filled with water, the adjusting member 30 is reset under the action of the elastic member 40 and returns to the first position, and the spoiler 33 approaches the first water outlet 26A, as shown in fig. 13-14.
In other embodiments, the opposite configuration may be adopted for the sliding direction of the adjusting member 30 after being driven by the water pressure, i.e. the first direction is defined as pointing from the second position to the first position, i.e. the water pressure pushes the spoiler 33 close to the first water outlet 26A. In this embodiment, the arrangement positions of the piston 32, the second water passing port 27B and the elastic member 40 may be adaptively changed, which is a simple replacement of the technical solution of embodiment 1, and the present invention will not be described again.
Returning again to embodiment 1, in order to enhance the effect of the water flow in the second switching chamber 24B, the regulating member 30 is further provided with a shut-off portion 35 which is slidably engaged with the second water passing port 27B and is adapted to reduce the flow velocity of the second water passing port when the regulating member is in the first position.
In this embodiment, the shut-off portion 35 has a pressing surface that is press-fitted with the second water passing port 27B when the regulating member 30 is in the first position, and is separated from the second water passing port 27B when the regulating member 30 is in the second position. Therefore, immediately before the second switching chamber 24B is drained and the effective pushing force on the piston 32 is not formed, the cut-off part 35 can reduce the draining speed of the second switching chamber 24B and rapidly increase the water pressure in the second switching chamber 24B when the adjusting member 30 is still at the first position; once the water pressure rises to a level that can push the piston 32, the cut-off portion 35 is separated from the second water passing port 27B, so that the water flow in the second switching cavity 24B can enter the first water outlet cavity 25A faster to be discharged, the water outlet speed in the state of switching is accelerated, and the response time after switching is reduced.
In particular, the shut-off portion 35 may be an end portion of the piston 32 facing the second water passing port, and a cross section thereof forms the pressing surface. Preferably, the shut-off portion may be a face seal secured to the end portion to completely seal the second water passing port 27B in the first position, providing a better shut-off effect. In a simpler structure, the cutoff part is an arbitrary shape member that can be inserted into the second water passing port 27B at the first position to reduce the flow rate of the water passing port, and the cutoff part is only required to be separated from the second water passing port 27B at the second position.
It will be appreciated that if the direction of sliding of the adjustment member 30 after being hydraulically actuated is configured to slide from the second position to the first position, the shut-off portion 35 should be configured to reduce the flow rate of the second water passing port 27B when the adjustment member is in the second position.
Next, the configuration of the spoiler 33 of the present embodiment will be described with reference to fig. 8 to 12, and fig. 13 to 16. It should be noted that various water outlet structures have been disclosed in the prior art, in which each of the water outlet structures includes a member capable of moving with respect to the water outlet hole to change the water outlet effect, and each of the water outlet structures can be used as a turbulence part of the present invention to replace the convex pillar of the following embodiment 1, so as to obtain a corresponding water outlet effect.
As shown in fig. 8 to 12, the turbulence part 33 is constructed as a convex column protruding from the side of the base plate 31, and the peripheral wall thereof is concavely provided with an inclined flow-through groove 331. The number of the oblique flow through grooves can be multiple, and the oblique flow through grooves are distributed at equal intervals along the periphery of the convex column. On the convex column, the oblique flow-through groove extends along a certain curve without mutual staggered interference.
The first water outlet 26A is of a conventional structure on the existing shower face cover, that is, a water inlet cavity 26A1 and a vortex cavity 26A2 are sequentially arranged along the water flow direction. The inner wall of the water inlet chamber 26A1 corresponds to the peripheral wall of the boss 33, and the vortex chamber 26A2 has a configuration in which a water cross section is tapered in a water flow direction, which is clearly shown in fig. 4, 14 and 16.
As shown in fig. 13 to 14, when the turbulence part 33 is inserted into the water inlet chamber 26A1, the water flow can only enter the water inlet chamber 26A1 along the inclined flow channel 331, which disturbs the water flow and forms a plurality of water flows having a rotational shearing effect, and then enters the vortex chamber 26A2. The multiple shear water streams collide with each other in the vortex chamber 26A2 and with the inner wall of the vortex chamber 26A2, so that the vortex direction and the vortex speed of the water streams are changed, forming spray water and water from the first water outlet hole 26A.
As shown in fig. 15 to 16, when the turbulence part 33 leaves the water inlet chamber 26A1, the water flows only through the inclined flow through groove, which cannot effectively disturb the water flow, and the water flow is directly rushed into the turbulence chamber 26A2 from the water inlet chamber 26A1, so that a spray with a special shape cannot be formed, and at this time, the first water outlet hole 26A discharges the ordinary shower.
Therefore, during the sliding process of the adjusting member 30, the protruding pillar 33 is slidably engaged with the first water outlet 26A, so that the oblique through-flow groove 331 is selectively inserted into the water inlet cavity 26A1 of the first water outlet 26A, and the vortex direction and the vortex speed of the water discharged from the first water outlet are changed, thereby changing the water outlet effect. It should be noted that, the different depths of insertion of the turbulence part 33 into the water chamber 26A1 can intuitively affect the particle fineness of the spray. Therefore, the specific water outlet effect of the spray in the first position can be adjusted after the movable stroke of the adjusting member 30 is correspondingly adjusted.
Referring again to fig. 1-7, in order to enrich the water outlet effect of the shower head of the present embodiment to have a third water outlet effect, the water outlet assembly 20 further has the following configuration.
The gland 21 and the water diversion member 22 further enclose a third switching cavity 24C, and the water diversion member 22 and the surface cover 23 further enclose a second water outlet cavity 25B which is communicated with the third switching cavity 24C. The surface cover 23 is also provided with a second water outlet hole 26B, and the second water outlet cavity 25B is used for discharging water through the second water outlet hole 26B. The water inlet channel 11 is in switching communication with the first switching chamber 24A, the second switching chamber 24B and the third switching chamber 24C.
When the water inlet channel 11 is switched to the third switching cavity 24C, the water flows through the second water outlet cavity 25B and the second water outlet hole 26B in sequence, and the water outlet effect depends on the specific structure of the water outlet module in the second water outlet cavity 25B, which is not limited by the present invention.
Embodiment 2 of the present invention also provides a multifunctional shower head differing from embodiment 1 only in that the elastic member 40 for resetting the regulating member is eliminated, and the movement direction of the regulating member 30 is still slid from the first position to the second position. In this embodiment, the adjusting member 30 needs to be configured to have a large self weight, and can reset by self weight when the second water outlet channel is not connected to the water inlet channel, so that the device is particularly suitable for use in a high water pressure environment.
The foregoing description of the embodiments and description is presented to illustrate the scope of the invention, but is not to be construed as limiting the scope of the invention. Modifications, equivalents, and other improvements to the embodiments of the invention or portions of the features disclosed herein, as may occur to persons skilled in the art upon use of the invention or the teachings of the embodiments, are intended to be included within the scope of the invention, as may be desired by persons skilled in the art from a logical analysis, reasoning, or limited testing, in combination with the common general knowledge and/or knowledge of the prior art.
