In the claims, the specification and the drawings of the present invention, unless otherwise specifically limited, the terms "fixedly connected" or "fixedly connected" should be understood in a broad sense, i.e., any connection mode without displacement relationship or relative rotation relationship between the two, i.e., including non-detachably fixed connection, and fixedly connected through other devices or elements.
Referring to fig. 1 to 4, embodiment 1 of the present invention provides a multifunctional shower head 1, including: body 10, gland 21, water-dividing piece 22, face lid 23, base plate 31, piston 32 and elastic piece 40.
A water inlet channel 11 is arranged in the body 10.
The gland 21, the water distributing part 22 and the surface cover 23 are fixedly connected with each other to form a water outlet assembly 20. A first water outlet channel and a second water outlet channel are formed in the water outlet assembly 20. The first water outlet channel and the second water outlet channel are switched and communicated with the water inlet channel 11 and are provided with a common water outlet hole so as to discharge water from the common water outlet hole.
One side of the base plate 31 is fixedly provided with a spoiler 33, and the other side thereof is fixedly connected with the piston 32 to form an adjusting member 30. When assembled, the piston 32 is slidably disposed in the second water outlet channel, so that the adjusting member 30 is slidably connected 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, and is used for resetting the adjusting member 30 when the second water outlet channel is not communicated with the water inlet channel 11.
In use, the first and second outlet channels are selectively communicated, and when the second outlet channel is flushed, the flow of water therein pushes the piston 32 to slide, so that the adjusting member 30 slides in a first direction between the first and second positions; when the second water outlet channel is not used, that is, when the first water outlet channel is switched to be used for water or the shower head is in a water-off state, the water flow acting force disappears, and the spring 40 drives the adjusting piece 30 to reset along the reverse direction of the first direction. When the water outlet hole is located at the first position, the turbulence part 33 is close to the water outlet hole, and water flows are disturbed by the turbulence part to be discharged; when the water outlet hole is located at the second position, the turbulent flow portion 33 is far away from the water outlet hole, and water flow is not disturbed to discharge water. Thus, the shower head has different water outlet effects when the adjusting member 30 is at different positions.
According to the shower head provided by the embodiment of the invention, the relative position and distance between the turbulence part 33 of the adjusting piece 30 and the water outlet hole are changed by switching whether the second water outlet channel is communicated with water or not, so that the water outlet effect of the common water outlet hole is switched. Therefore, the shower head only needs to switch and communicate the water inlet channel 11 to the first water outlet channel and the second water outlet channel, and then utilizes the principles of water pressure driving and elastic resetting to enable the turbulence part 33 to move and reset along the preset path, so that the switching of the water outlet effect of the same water outlet hole can be realized, and the shower head is stable and reliable.
Furthermore, the present invention, since the regulator 30 is driven by the water pressure in the water outlet assembly 20, actually divides the entire driving link formed from the user operating end to the spoiler 33 into two independently constructed parts. One part of the water outlet assembly is an integral module formed by assembling the adjusting part 30 to the water outlet assembly 20, and the other part of the water outlet assembly can directly adopt various existing switching devices, and only simple waterway switching is needed, so that the two parts can be connected seamlessly to form the driving link. Therefore, the whole module can adapt to other switching modes and devices at the user operation end, not only can meet the requirement of diversification of the operation modes of the multifunctional shower head on the market, but also can use the existing switching module when the product is produced, and the modularized design and manufacture are realized. In addition, to form the integral module, the adjusting part is only assembled in the water outlet assembly, and part of the adjusting part is positioned in the second water outlet channel, and the inner structure of the integral module is not complex, so that the integral module has a larger cost advantage.
Specifically, in order to realize the above switching, the present embodiment adopts a switching manner in which the whole body of the water outlet assembly 20 rotates relative to the body 10, that is, a conventional switching manner of a rotating surface cover. It can be seen that the driving and transmission components required for driving the spoiler 33 to move 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 button switch, a push button switch, or the like may be used instead of the above-mentioned switching manner of the rotating surface cover, as long as the water inlet channel 11 can be switched to communicate with the first water outlet channel and the second water outlet channel. The implementation mode of the switching is a common technical means in the field of multifunctional showers, and the switching mode is not limited by the invention.
In addition, the adjusting member 30 is driven by the water pressure of the water flow in the water outlet assembly 20, so that the user only needs to overcome the corresponding resistance for switching the first water outlet channel and the second water outlet channel during operation, and the water pressure and the resistance borne by the adjusting member do not need to be overcome, and the operation is light. In the prior similar shower head, the adjusting piece in water is driven by mechanical transmission among parts, so that when a user operates the shower head, the mechanical resistance of a complex transmission mechanism needs to be overcome, the water pressure action of water flow on the end face of the adjusting piece 30 needs to be overcome, the required operating force is increased, and the operation is difficult.
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 make the turbulence portion 33 approach or separate from the water outlet to disturb the water flow entering the water outlet, the embodiment is not limited to make the turbulence portion 33 slide relative to the water outlet. In other embodiments, the impeller in the prior art can be used to replace the piston, and the spoiler portion 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 enters 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, vortex portion and apopore cooperation carry out the vortex to rivers to change the play water effect. In this embodiment, the elastic member may be a torsion spring.
Returning to embodiment 1 and referring to fig. 1 to 7, in particular, in the water outlet assembly 20, the pressing cover 21 and the water dividing member 22 surround to form a first switching chamber 24A and a second switching chamber 24B, and the water dividing member and the surface cover surround to form a first water outlet chamber 25A, and the surface cover is provided with a first water outlet hole 26A corresponding to the first water outlet chamber 25A. In addition, the water dividing member 22 is further provided with a first water passing opening 27A and a second water passing opening 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 outlet chamber 25A and the first outlet hole 26A are communicated to form the second outlet channel. In particular, during switching, the water inlet channel 11 switches and communicates the first switching cavity 24A and the second switching cavity 24B.
The base plate 31 is slidably arranged in the first water outlet cavity 25A; the piston 32 passes through the second water passing opening 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 filled with water, so that the regulating part 30 slides along a first direction relative to the water outlet assembly 20; the turbulent flow portion 33 is slidably disposed in the first water outlet cavity 25A and slidably engaged with 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 outlet hole 26A. On this basis, the water outlet assembly 20 and the adjusting member 30 are further configured to have the following specific structure.
In order to enable the piston 32 to be effectively and stably pushed by the water flow, the piston is configured to have an end surface facing the base plate 31 and not contacting the bottom of the second switching chamber 24B (the upper end surface of the water separator 22 in this embodiment) when the adjuster 30 is located at the first position. Thus, when water flows through the second switching chamber 24B, the water flow exerts pressure on the end surface, and the adjuster 30 slides to the second position.
The water outlet assembly 20 (in this embodiment, the pressing cover 21) is further provided with a protrusion at a position corresponding to the second switching chamber 24B, and a sliding groove 28 for the piston to slide is formed in the protrusion, and the sliding groove forms a part of the second switching chamber. The peripheral wall of the piston 32 is in sealing engagement with the inner wall of the chute 28 and the top of the projection, i.e. the bottom of the chute 28, is provided with a vent hole 29. Therefore, the piston 32 is slidably disposed in the slide groove 28, and divides the second switching chamber 24B into a water passing portion and a non-water passing portion, and when water passes through the second switching chamber, the non-water passing portion can be communicated with the atmosphere through the exhaust hole 29, so that the piston can be pushed to slide in the slide groove 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, and the assembly is convenient.
Furthermore, in this embodiment, one end of the spring 40 abuts against the top wall of the first water outlet cavity 25A (in this embodiment, the lower end surface of the water dividing member 22), and the other end abuts against the base plate 31. As the adjuster 30 slides from the first position to the second position, the spring 40 compresses and accumulates elastic potential energy to urge the adjuster 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 openings 34, which not only can reduce the weight of the adjusting member 30 and make it lighter and easier to push, but also can accelerate the flow rate of the water flowing from the second water passing opening 27B through the base plate 31 to the first water outlet hole 26A in the first water outlet cavity 25A, so as to accelerate the water outlet speed after switching and reduce the response time after switching.
Referring to fig. 13-16, when the sprinkler is operated, the adjusting member 30 slides from the first position to the second position by the water pressure when the second switching chamber 24B is filled with water, and the disturbing part 33 is away from the first outlet hole 26A, as shown in fig. 15-16; when the second switching chamber 24B is not filled with water, the adjusting member 30 is reset by the elastic member 40 and returns to the first position, and the spoiler 33 is close to the first outlet hole 26A, as shown in fig. 13-14.
In other embodiments, the sliding direction of the adjusting member 30 driven by the water pressure may be reversed, that is, the first direction is defined as the direction from the second position to the first position, that is, the water pressure pushes the spoiler 33 to be close to the first outlet hole 26A. In this embodiment, the arrangement positions of the piston 32, the second water passing opening 27B and the elastic member 40 may be modified adaptively, which is a simple replacement of the technical solution in embodiment 1, and the present invention is not 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 fixedly provided with a cut-off portion 35 which is in sliding fit with the second flow-passing opening 27B and is used for reducing the flow-passing speed of the second flow-passing opening when the regulating member is in the first position.
In this embodiment, the cut-off portion 35 has a press-fit surface which is in press-fit engagement with the second flow port 27B when the adjusting member 30 is in the first position and which is spaced from the second flow port 27B when the adjusting member 30 is in the second position. Therefore, when the adjusting member 30 is still at the first position before the second switching chamber 24B is just filled with water and does not form an effective pushing force on the piston 32, the cut-off portion 35 can reduce the water discharge speed of the second switching chamber 24B and rapidly increase the internal water pressure thereof; once the water pressure rises to push the piston 32, the cut-off part 35 leaves the second water passing opening 27B, and the water flow in the second switching chamber 24B can quickly enter the first water outlet chamber 25A for water outlet, so that the water outlet speed in the state of switching to the state is accelerated, and the response time after switching is shortened.
In a specific implementation, the cut-off portion 35 may be an end portion of the piston 32 facing the second drainage port, and a cross section of the cut-off portion constitutes the pressing surface. Preferably, the cut-off portion may also be an end face sealing member fixedly arranged on the end portion, so as to completely seal the second water passing opening 27B in the first position, thereby providing a better cut-off effect. A simpler construction is that the cut-off portion is a part of any shape that can be inserted into the second delivery opening 27B in the first position to reduce its delivery rate, but only needs to be removed from the second delivery opening 27B in the second position.
It will be appreciated that if the sliding direction of the regulating member 30 driven by the hydraulic pressure is configured to slide from the second position to the first position, the cut-off portion 35 should be configured to reduce the flow rate of the second water passing opening 27B when the regulating 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, each of which includes a component capable of moving in relation to the water outlet hole to change the water outlet effect, and each of which can be used as a spoiler of the present invention to replace the convex pillar of the following embodiment 1, so as to obtain the corresponding water outlet effect.
In fig. 8 to 12, it is shown that the spoiler 33 is configured as a convex column protruding from one side of the substrate 31, and a circumferential wall thereof is concavely provided with an oblique flowing groove 331. The quantity of this slant overflow groove can be a plurality of to arrange along the periphery equidistance interval of projection. On the convex column, the oblique overflow groove extends along a certain curve without mutual staggered interference.
The first outlet hole 26A is of a conventional structure on a conventional shower head cover, i.e. 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 convex column 33, and the vortex chamber 26a2 has a configuration with a tapered water cross section in the water flow direction, which is clearly shown in fig. 4, 14 and 16.
As shown in fig. 13-14, when the spoiler 33 is inserted into the water inlet chamber 26a1, the water flow can only enter the water inlet chamber 26a1 along the oblique overflow groove 331, which disturbs the water flow and forms a plurality of water flows with a rotating shearing effect, and then enters the vortex chamber 26a 2. The multiple shear streams collide with each other in vortex chamber 26A2 and with the inner wall of vortex chamber 26A2, so that the direction and speed of the vortex of the streams change, forming a spray pattern and exiting first outlet opening 26A.
As shown in fig. 15-16, when the turbulent flow portion 33 leaves the water inlet chamber 26A1, the water flow only flows through the oblique flowing groove, which cannot effectively disturb the water flow, and the water flow is directly rushed into the vortex chamber 26A2 from the water inlet chamber 26A1, so that a special form of spray cannot be formed, and the first water outlet hole 26A emits the ordinary shower water.
Therefore, during the sliding process of the adjusting member 30, the protruding pillar 33 is in sliding fit with the first outlet hole 26A, so that the inclined flowing groove 331 is selectively inserted into the water inlet cavity 26A1 of the first outlet hole 26A, and the vortex direction and the vortex speed of the outlet water of the first outlet hole are changed, thereby changing the water outlet effect. It should be noted that the depth of the turbulent flow portion 33 inserted into the water cavity 26a1 is different, and the particle fineness of the spray can be intuitively influenced. Therefore, after the moving stroke of the adjusting member 30 is adjusted accordingly, the specific water outlet effect of the spray when the adjusting member is at the first position can be adjusted.
Referring again to fig. 1-7, in order to enrich the water outlet effect of the shower head of the present embodiment so as to have a third water outlet effect, the water outlet assembly 20 further has the following configuration.
The gland 21 and the water dividing piece 22 further surround and form a third switching cavity 24C, and the water dividing piece 22 and the surface cover 23 further surround and form a second water outlet cavity 25B which is communicated with the third switching cavity 24C. The surface cover 33 is further 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 communicated with the first switching cavity 24A, the second switching cavity 24B and the third switching cavity 24C in a switching way.
When the water inlet channel 11 is switched to the third switching chamber 24C, the water flow passes through the second water outlet chamber 25B and the second water outlet hole 26B in sequence to discharge water, and the water discharge effect depends on the specific structure of the water discharge module in the second water outlet chamber 25B, which is not limited in the present invention.
Embodiment 2 of the present invention further provides a multifunctional shower head, which is different from embodiment 1 only in that the elastic member 40 for resetting the adjusting member is eliminated, and the moving direction of the adjusting member 30 is still sliding from the first position to the second position. In this embodiment, the adjusting member 30 needs to be configured to have a relatively large self-weight, and can be automatically reset by its own weight when the second water outlet channel is not communicated with the water inlet channel, and is particularly suitable for use in a high water pressure environment.
The description of the above specification and examples is intended to be illustrative of the scope of the present invention and is not intended to be limiting. Modifications, equivalents and other improvements which may occur to those skilled in the art and which may be made to the embodiments of the invention or portions thereof through a reasonable analysis, inference or limited experimentation, in light of the common general knowledge, the common general knowledge in the art and/or the prior art, are intended to be within the scope of the invention.
