Abstract
Description
Technical Field
[0001] This invention relates to the field of shower heads, and in particular to a shower head. Background Technology
[0002] After showerheads are used, residual water remains inside. This residual water can easily breed bacteria or accumulate limescale, clogging the nozzles and affecting the showerhead's normal operation. Some existing technologies connect the showerhead's outlet chamber to the outside after the shower stops to balance the pressure inside and outside, allowing the residual water to drain out under its own weight. However, because drainage relies solely on the water's own weight, the drainage process is slow. Furthermore, because the water outlet's cross-sectional area is often relatively small, the water's surface tension can prevent subsequent water flow from being properly discharged, resulting in incomplete removal of residual water. Summary of the Invention
[0003] This invention proposes a shower head that aims to solve the technical problem of difficulty in draining residual water from shower heads in the prior art, making it difficult to completely drain the water.

The transmission component has a first state in which it can rotate relative to the rotating shaft hole and a second state in which it is driven to the rotating shaft hole.
[0032] When water flows into the water passage cavity, the driving member is impacted and rotates in the first direction, causing the energy storage component to store energy, and the transmission component is in the first state. When no water flows through the water passage cavity, the energy storage component drives the driving member to rotate in the second direction, and the transmission component is in the second state.

[0064] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0065] refer to Figure 1 In some specific embodiments of the present invention, a shower head 1000 is provided, which can utilize gas from an external air source to completely remove residual water that cannot be discharged after the water flow stops, thus preventing dripping, bacterial growth in residual water, and other problems. It is particularly important to note that the "external air source" referred to here and thereafter can be the ambient atmosphere or a gas supply device such as a gas cylinder other than the shower head 1000.
[0066] refer to Figure 1-3The shower head 1000 provided in this embodiment includes a first housing 100 and an air intake device 300. The first housing 100 includes a water inlet channel 121, a water outlet chamber 150, and a water outlet channel 141 arranged sequentially. Water can flow from the water inlet channel 121 into the water outlet chamber 150 and out through the water outlet channel 141 for use. The first housing 100 is also provided with an air intake chamber 240. At least one air outlet 211 is provided on the wall of the air intake chamber 240. The air outlet 211 penetrates the wall of the air intake chamber 240, and the gas in the air intake chamber 240 can enter the water outlet chamber 150 through the air outlet 211 to increase the air pressure in the water outlet chamber 150, thereby squeezing the residual water in the water outlet chamber 150 out of the water outlet channel 141, thus avoiding dripping, bacterial growth, and other phenomena.
[0067] The suction device 300 is disposed in the suction chamber 240. The suction device 300 includes a piston diaphragm assembly 310, a first one-way member 340, and a drive assembly 330.
[0068] A piston diaphragm assembly 310 is disposed in the intake chamber 240. The piston diaphragm assembly 310 includes at least one bowl 311, the opening of which faces the outlet 211. The bowl 311 and the inner wall of the intake chamber 240 form a pump chamber 320. The inlet end of the outlet 211 communicates with the pump chamber 320. Thus, when the volume of the pump chamber 320 decreases, the gas in the pump chamber 320 can be driven to be discharged from the outlet 211. A first one-way member 340 is disposed on the outlet 211 to control the gas in the pump chamber 320 to leave the pump chamber 320 unidirectionally from the outlet 211. The drive assembly 330 is driven to connect with the bowl 311. When the drive assembly 330 moves, it can control the movement and / or deformation of the bowl 311, thereby changing the volume of the pump chamber 320. At this time, the drive assembly 330 and the bowl 311 are equivalent to an "air pump". During the operation of the "air pump", when the volume of the pump chamber 320 decreases, the gas in the pump chamber 320 can leave the pump chamber 320 through the air outlet 211.
[0069] Understandably, when water flows into the shower head 1000 during normal use, the gas in the pump chamber 320 does not enter the outlet chamber 150 to avoid affecting the water flow. Only when no water flows into the shower head 1000, that is, when the shower head 1000 has finished using and no longer flows water, will the gas enter the outlet chamber 150 to remove the residual water.
[0070] refer to Figure 2-3In some specific embodiments, the air outlet 211 can be directly connected to the water outlet chamber 150. In this case, when water flows into the shower head 1000, the drive component 330 does not control the movement and / or deformation of the bowl 311, and no gas enters the water outlet chamber 150. When the shower head 1000 is no longer in use and no water flows into it, the drive component 330 can drive the bowl 311 to move and / or deform, thereby allowing gas to enter the water outlet chamber 150. For example, the drive component 330 may include a processor, a hydroelectric generator, a power storage device, and a transmission mechanism. When water flows into the shower head 1000, the hydroelectric generator starts and generates electrical energy, which is stored in the power storage device. Through a program preset in the processor, when the power storage device no longer receives electrical energy input from the hydroelectric generator (i.e., the shower head 1000 is no longer in use and no more water flows into it), the power storage device drives the transmission mechanism, causing the transmission mechanism to drive the bowl 311 to move and / or deform. Alternatively, the drive assembly 330 may include a deformable and recoverable elastic mechanism that deforms and stores energy when water flows into the shower head 1000, and recovers its shape and drives the bowl 311 to move and / or deform after the shower head 1000 has been used.
[0071] According to the specific embodiments provided by the present invention, after the shower head 1000 is used (when no water flow enters), gas can be sent into the water outlet chamber 150 to increase the air pressure in the water outlet chamber 150, thereby discharging the residual water in the water outlet chamber 150 and avoiding problems such as dripping water or bacterial growth in residual water after the shower head 1000 is turned off.
[0072] It is understandable that the drive component 330 can also be other power devices that can achieve the driving effect, and no specific limitation is made here.
[0073] It is understandable that the first one-way component 340 can be a one-way valve, a check valve, etc., which is fixedly installed on the vent 211, or it can be a structure with a membrane. Specifically, the area of the membrane is larger than the cross-sectional area of the vent 211. The position and area of the membrane restrict the membrane to deform only along the side opposite to the vent 211, thereby exposing the vent end of the vent 211.
[0074] refer to Figure 2 , 3 In some specific embodiments of the present invention, the first housing 100 further includes a second housing 200, which encloses an air intake chamber 240. Specifically, the second housing 200 may be a part of the first housing 100, integrally formed with the first housing 100, or it may be an independent housing structure assembled within the first housing 100. An air outlet 211 is disposed on one wall surface of the second housing 200.
[0075] refer to Figure 4In some specific embodiments of the present invention, the second housing 200 includes a cylindrical portion 220, on which a first partition plate 221 is arranged radially. A cylinder 222 is arranged on the first partition plate 221. Specifically, the cylinder 222 extends outward in a direction away from the vent 211. The cylinder 222 is hollow and communicates with the vent 211. Specifically, the end of the cylinder 222 near the vent 211 can be completely hollowed out, in which case the end of the vent 211 directly communicates with the space inside the cylinder 222. Alternatively, the end of the cylinder 222 near the vent 211 can still be blocked by the first partition plate 221. An opening penetrating the first partition plate 221 is provided on the first partition plate 221 enclosed in the cylinder 222. The opening corresponds to the vent 211, thereby enabling the vent 211 to communicate with the space inside the cylinder 222.
[0076] The bowl 311 is slidably disposed in the cylinder 222, and the outer peripheral wall of the bowl 311 is sealed against the inner wall of the cylinder 222.
[0077] It is understandable that when the end of the cylinder 222 near the air outlet 211 is completely hollowed out, the bowl 311, the cylinder 222, and the wall of the second shell 200 form a pump cavity 320.
[0078] Therefore, when the bowl 311 is driven to slide back and forth in the cylinder 222, the volume of the pump chamber 320 changes, thereby completing the inflation process. It can be understood that if the bowl 311 is made of a deformable material such as rubber, when the bowl 311 moves to abut against the first partition plate 221, it can continue to deform towards the air outlet 211, and the gas inside the bowl 311 is also input into the air outlet 211.
[0079] refer to Figure 3 , 4 In some specific embodiments of the present invention, the first housing 100 is further provided with an air intake channel 250, which connects the air intake chamber 240 and an external air source.
[0080] The air intake channel 250 can be disposed on the second housing 200. Specifically, the air intake channel 250 can be a gas channel disposed on the second housing 200, which connects the air intake chamber 240 to an external air source. Alternatively, the air intake channel 250 can be an opening on the second housing 200, connecting the air intake chamber 240 and the internal space of the shower head 1000 outside the second housing 200. The internal space of the shower head 1000 is connected to an external air source, thereby allowing gas to enter the air intake chamber 240 through the air intake channel 250.
[0081] In some specific embodiments of the present invention, the shower head 1000 is also provided with an air replenishment channel. When the air intake device 300 continuously inflates the air outlet 211, the volume of the pump chamber 320 continuously circulates in the process of "shrinking-restoring". The air replenishment channel is used to input gas into the pump chamber 320 during the restoration process to maintain the pressure balance inside and outside the pump chamber 320 and ensure that there is enough gas in the pump chamber 320 when it is inflated again.
[0082] Specifically, one end of the air supply channel is connected to the pump chamber 320, and the other end is connected to the suction chamber 240, so that the gas in the suction chamber 240 can enter the pump chamber 320 through the air supply channel.
[0083] In some embodiments, the air supply channel can be disposed on the bowl portion 311 (not shown). Specifically, the air supply channel penetrates the peripheral wall of the bowl portion 311. In this embodiment, the cross-sectional area of the air supply channel can be designed to be extremely small, and a first one-way component 340 (such as a check valve) that can be opened unidirectionally with only a small pressure is selected. Thus, when the pump chamber 320 shrinks, most of the gas enters the outlet 211, and only a very small amount of gas can enter the intake chamber 240 through the air supply channel, and its impact on the inflation process is negligible. When the pump chamber 320 recovers, the outlet 211 is closed due to the first one-way component 340, and only the gas in the intake chamber 240 can enter the pump chamber 320 through the air supply channel.
[0084] In some specific embodiments of the present invention, the shower head 1000 is also provided with a second one-way component. Specifically, the second one-way component is provided on the air supply channel to control the gas in the air intake chamber 240 to enter the pump chamber 320 in one direction.
[0085] In this embodiment, due to the provision of a second one-way component, when the pump chamber 320 is filled with air to the air outlet 211, the gas cannot enter the air intake chamber 240 from the air replenishment channel. Therefore, the cross-sectional area of the air replenishment channel does not need to be limited to a certain range at this time, and the cross-sectional area can be appropriately increased to improve the air replenishment speed.
[0086] It is understandable that the second one-way component can be a check valve, a shut-off valve, or a foldable diaphragm 314, and the diaphragm 314 can only be folded back and forth in the direction of gas supply to open and close the gas supply channel.
[0087] refer to Figure 3 In some specific embodiments of the present invention, the second housing 200 includes a first cover assembly and a second cover 230, wherein an air outlet 211 and an air replenishment channel are disposed on the first cover assembly.
[0088] Understandably, the air replenishment channel can also meet the air replenishment requirements by designing an appropriate air passage cross-sectional area.
[0089] refer to Figure 3-5 In some specific embodiments of the present invention, the air supply channel includes an air supply groove 212 and an air supply hole 2211. The first cover assembly includes a first cover 210 and a cylindrical portion 220. The cylindrical portion 220 has a hollow design, and its two ends are respectively connected to the first cover 210 and the second cover 230. The first cover 210 is provided with an air outlet 211 and an air supply groove 212. Specifically, the air outlet 211 penetrates the first cover 210, and the air supply groove 212 (not penetrating the first cover 210) is hollowed out on the side of the first cover 210 opposite to the air outlet end of the air outlet 211. The cylindrical portion 220 extends a first partition plate 221 along its own radial direction, and the air supply hole 2211 is disposed on the first partition plate 221 and penetrates the first partition plate 221.
[0090] The pump chamber 320, the air supply groove 212, and the air supply hole 2211 are arranged in sequence. The end of the air supply hole 2211 facing away from the air supply groove 212 is connected to the air intake chamber 240. When the pump chamber 320 completes one inflation to the air outlet 211 and then recovers, the gas in the air intake chamber 240 can enter the pump chamber 320 after passing through the air supply hole 2211 and the air supply groove 212.
[0091] refer to Figure 2 , 6 In some specific embodiments of the present invention, the bowl portion 311 is at least partially made of a deformable material, and a membrane portion 312 is provided on the open side of the bowl portion 311, the membrane portion 312 being sandwiched between the first cover 210 and the cylindrical portion 220. At this time, the bowl portion 311 is essentially fastened to the first cover 210, and together with the first cover 210, forms a pump cavity 320. It can be understood that at this time, the end of the air supply groove 212 facing away from the air supply hole 2211 is located in the projection of the bowl portion 311 along the axial direction of the cylindrical portion 220.
[0092] According to an embodiment of the present invention, since the membrane portion 312 on the opening side of the bowl portion 311 has been clamped and positioned, when the driving component 330 applies force to the bowl portion 311 in the direction close to the air outlet 211, the bowl portion 311 only deforms without moving, and the volume of the pump chamber 320 shrinks to complete the inflation. When the driving component 330 applies force in the direction away from the air outlet 211, the shape of the bowl portion 311 is restored or even stretched and deformed, the volume of the pump chamber 320 increases, and gas enters the pump chamber 320 from the gas replenishment channel.
[0093] refer to Figure 2 , 46. In some specific embodiments of the present invention, the first partition plate 221 further includes a cylinder 222. Specifically, the cylinder 222 extends outward in the direction away from the air outlet 211. The cylinder 222 is hollow and communicates with the air outlet 211. The bowl 311 is disposed in the cylinder 222. When the drive assembly 330 moves, the membrane portion 312 of the bowl 311 is clamped. At this time, the bowl 311 deforms in the cylinder 222, thereby changing the volume of the pump chamber 320. This avoids the bowl 311 from shifting during the deformation process and interfering with other structural components in the shower head 1000, thus affecting the inflation and replenishment effect.
[0094] In some embodiments (not shown), the piston diaphragm assembly 310 may have only one bowl 311, and the drive assembly 330 is only driven connected to the bowl 311 and completes the inflation process through the bowl 311.
[0095] In some embodiments, the piston diaphragm assembly 310 comprises a plurality of bowls 311, and the drive assembly 330 is simultaneously driven and connected to the plurality of bowls 311, and simultaneously completes the inflation process through the plurality of bowls 311. Specifically, the driving method can also be various different methods. For example, the drive assembly 330 drives the plurality of bowls 311 to move simultaneously in one direction, so that the plurality of bowls 311 are simultaneously inflated or replenished with air. Alternatively, the driven direction of at least one of the plurality of bowls 311 is opposite to that of the other bowls 311. For example, the driven directions of any two adjacent bowls 311 may be different. Or, the plurality of bowls 311 may be arranged in an array along a circle, a square, or the like, and the plurality of bowls 311 sequentially complete the inflation and replenishment process along a certain direction of the array and continuously cycle.
[0096] refer to Figure 6 In some specific embodiments of the present invention, the piston membrane assembly 310 is provided with N bowls 311, where N is an integer greater than or equal to 2, and can be 3, 4 or more. The N bowls 311 are connected by membranes 312, which can be connected to each other to form a membrane structure with a large area. The N bowls 311 are disposed in the membranes 312, and the number of cylinders 222 is the same as the number of bowls 311. Specifically, the membranes 312 with N bowls 311 are disposed on the side of the first partition plate 221 near the first cover 210. The skirt of the membranes 312 is clamped between the cylinders 220 and the first cover 210, and the N bowls 311 are disposed in a one-to-one correspondence with the N cylinders 222.
[0097] Understandably, the first cover 210 also has N air outlets 211 and air replenishment grooves 212, and the first partition plate 221 is provided with N air replenishment holes 2211. Thus, under the action of the drive assembly 330, each bowl 311 can complete the process of inflation and replenishment in the corresponding cylinder 222.
[0098] refer to Figure 6 , 7 In some specific embodiments of the present invention, the membrane portion 312 is provided with a vent 313 corresponding to the gas supply hole 2211, thereby preventing the membrane portion 312 from blocking the gas flow between the gas supply hole 2211 and the gas supply groove 212. The vent 313 can be configured with a large aperture, thereby encompassing all N gas supply holes 2211. Alternatively, the vent 313 can be configured as N smaller aperture holes, corresponding one-to-one with each gas supply hole 2211.
[0099] In some specific embodiments of the present invention, the second one-way member is disposed in the vent 313.
[0100] Specifically, the second one-way component can be a one-way valve, a check valve, or a plate or diaphragm that can only be folded in one direction, as long as it allows gas to enter the pump chamber 320 from the gas supply channel in one direction.
[0101] refer to Figure 6 , 7 In some specific embodiments of the present invention, the second one-way component includes a diaphragm 314 and a first connecting portion 315 disposed on the outer edge of the diaphragm 314. The diaphragm 314 is disposed in the vent 313 and connected to the vent 313 or the air replenishment hole 2211 through the first connecting portion 315. When the diaphragm 314 is connected to the air replenishment hole 2211, the specific position of the diaphragm 314 is on the side of the air replenishment hole 2211 close to the air replenishment groove 212. Specifically, the area of the diaphragm 314 is larger than the air passage cross-sectional area of the vent 313 or the air replenishment hole 2211. The first connecting portion 315 is disposed at any point on the outer edge of the diaphragm 314. When the other end of the first connecting portion 315 is connected to the vent 313 or the air replenishment hole 2211, the diaphragm 314 can be folded with the first connecting portion 315 as the axis.
[0102] In this embodiment of the invention, when gas enters the replenishment channel from the intake chamber 240, the gas can drive the diaphragm 314 to fold in the direction close to the pump chamber 320, thereby opening the vent 313 or the replenishment port 2211. When gas enters the replenishment groove 212 from the pump chamber 320, the diaphragm 314 is covered on the vent 313 or the replenishment port 2211 under the drive of the gas, cutting off the connection between the replenishment groove 212 and the replenishment port 2211, so that the gas cannot enter the intake chamber 240, thereby restricting the flow direction of the gas.
[0103] It is understandable that the diaphragm 314 is part of the membrane portion 312. An arc-shaped cut can be provided on the membrane portion 312, and the part of the membrane portion 312 surrounded by the cut is the diaphragm 314. It is only necessary to set an appropriate arc shape and size so that the diaphragm 314 can be folded.
[0104] refer to Figure 2 , 3 In some specific embodiments of the present invention, the drive assembly 330 includes a drive member 331, a drive shaft 332 and a drive disk 333. The drive disk 333 is drivenly connected to the bowl portion 311. The drive member 331 and the drive disk 333 are respectively disposed at both ends of the drive shaft 332. Thus, the drive member 331 can use the drive shaft 332 to move the drive disk 333, thereby controlling the movement and / or deformation of the bowl portion 311.
[0105] It is understandable that the drive assembly 330 can be entirely housed in the air intake chamber 240, or the drive component 331 can be housed outside the air intake chamber 240 (but still within the shower head 1000), the drive disc 333 can be housed in the air intake chamber 240, and the drive shaft 332 can be connected to the second housing 200.
[0106] It is understood that the drive component 331 may include a motor, and the drive shaft 332 is driven by the motor to cause the drive disc 333 to reciprocate along the axial direction of the drive shaft 332, thereby driving the bowl 311 to move and / or deform. The drive component 331 may be directly connected to a power supply, or it may be connected to a hydroelectric power generation device, using the water output from the shower head 1000 to power the motor.
[0107] It is understandable that the drive component 331 can also be an impeller, turbine, etc. The drive assembly 330 is set in the air intake chamber 240 where the water flows. The water flow impacts the drive component 331 to rotate. At this time, the drive component 331 does not control the movement of the drive disc 333. The shower head 1000 can use some energy storage devices to store the kinetic energy of the water flow. When the shower head 1000 is finished using and no more water flows in, the energy storage device releases energy and causes the drive disc 333 to reciprocate along the axial direction of the drive shaft 332.
[0108] refer to Figure 6 , 8 In some specific embodiments of the present invention, the drive disk 333 is provided with N first hinge members 3331, and the cup portion 311 is provided with a second hinge member 316 on the side facing away from the pump cavity 320. The drive disk 333 and the cup portion 311 are connected one-to-one by the first hinge members 3331 and the second hinge members 316. The first hinge members 3331 are arranged in a circular array on the outer edge of the drive disk 333, with the connection point between the drive disk 333 and the drive shaft 332 as the center.
[0109] Specifically, one of the first hinge member 3331 and the second hinge member 316 can be an annular sleeve, and the other can be a ball head. The annular sleeve can be fitted onto the ball head, thereby realizing the drive. The first hinge member 3331 and the second hinge member 316 can also both be fasteners or other connecting structures, as long as they can realize the connection function. No specific limitation is made here.
[0110] refer to Figure 8 In some specific embodiments of the present invention, the drive disk 333 is bowl-shaped and its opening faces away from the piston membrane assembly 310.
[0111] In a specific embodiment of the present invention, the bowl-shaped design of the drive disc 333, compared to the flat drive disc 333, results in a greater distance between the drive disc 333 and the air outlet 211 in the initial state. Furthermore, when the drive disc 333 moves away from the air outlet 211, the other side of the drive disc 333 also has a greater stroke before interfering with the inner wall of the air intake chamber 240. Therefore, the bowl 311 travels further during the inflation process. Thus, through the cooperation between the first hinge 3331 and the second hinge 316, the bowl 311 can be stretched, moved, and / or deformed to a greater extent in the direction away from the air outlet 211, allowing more gas to be drawn in and input into the air outlet 211, making the inflation process faster and more efficient.
[0112] refer to Figure 2-3 8-9. In some specific embodiments of the present invention, the second cover 230 is provided with a first shaft hole 231, the axis of the first shaft hole 231 is parallel to the axis of the cylindrical part 220, and the drive shaft 332 passes through the first shaft hole 231. Specifically, the drive shaft 332 includes a first shaft segment 3321 and a second shaft segment 3323, wherein the included angle β between the first shaft segment 3321 and the second shaft segment 3323 is an obtuse angle, and the first shaft segment 3321 partially passes through the first shaft hole 231. At this time, the second... Shaft segment 3323 is located in the air intake chamber 240. The part of the first shaft segment 3321 facing away from the second shaft segment 3323 is located outside the air intake chamber 240 and connected to the drive member 331 so as to be driven to rotate by the drive member 331. The drive disk 333 is disposed in the air intake chamber 240 and pivotally connected to the second shaft segment 3323. Specifically, the drive disk 333 is roughly in the shape of a disc. The drive disk 333 has a second shaft hole 3332 in the middle. The second shaft segment 3323 passes through the second shaft hole 3332 to complete the pivot connection.
[0113] Specifically, the drive unit 331 can be a motor that rotates the drive shaft 332, or it can be an impeller. When the impeller rotates due to the impact of water flow, the drive shaft 332 rotates accordingly.
[0114] In this embodiment of the invention, when the shower head 1000 is in the initial state, due to the inclined design of the second shaft segment 3323, the drive disc 333 is also inclined relative to the first shaft segment 3321. That is, one side is relatively close to the drive member 331, and the other side is relatively close to the air outlet 211. The bowl 311 on one side is stretched while the bowl 311 on the other side is compressed and folded. When the drive member 331 causes the drive shaft 332 to rotate, the second shaft segment 3323 rotates around the axis of the first shaft segment 3321. The rotation trajectory of the second shaft segment 3323 is roughly conical. Since the second shaft segment 3323 and the second shaft hole 3332 of the drive disc 333 are pivotally connected, the drive disc 333 does not rotate at this time, but moves back and forth along the first hinge member 3331 in the circumferential direction of the drive disc 333. As a result, the drive bowl 311 also moves back and forth continuously, thereby completing the process of inflation and replenishment.
[0115] It should be noted that even if there is friction between the second shaft segment 3323 and the second shaft hole 3332, since the drive disk 333 and the bowl portion 311 are already connected, even if the drive disk 333 has a slight tendency to rotate due to friction, the connection between the first hinge 3331 and the second hinge 316 can overcome this friction and prevent the drive disk 333 from rotating.
[0116] refer to Figure 2 In some specific embodiments of the present invention, the first housing 100 further includes a water passage cavity 160, which is disposed between the water inlet channel 121 and the water outlet cavity 150. Water in the water inlet channel 121 can flow through the water passage cavity 160 and then into the water outlet cavity 150. A driving member 331 is disposed in the water passage cavity 160. When water flows through the water passage cavity 160 and impacts the driving member 331, the driving member 331 can be rotated.
[0117] It should be noted here that during the water flow impact motion, the drive component 331 can use the energy storage device to convert and store the kinetic energy of the water flow, and does not control the deformation of the pump chamber 320. Furthermore, when the water flow stops entering the shower head 1000, the energy storage device releases energy and keeps the drive component 331 in motion for a period of time, and only then will the deformation of the pump chamber 320 be controlled.
[0118] refer to Figure 2 In some embodiments, the water passage chamber 160 and the water outlet chamber 150 are connected by a water passage channel 170.
[0119] refer to Figure 2 , 10In some specific embodiments of the present invention, an annular plate 115 is provided on the side of the first housing 100 near the second cover 230 or on the side of the second cover 230 away from the air intake chamber 240. By providing the annular plate 115, the second cover 230 and the first housing 100 form a water passage chamber 160. The annular plate 115 is provided with a water outlet 1152 and a plurality of inclined water holes 1151. The inclined water holes 1151 connect the water inlet channel 121 and the water passage chamber 160, and the water outlet 1152 connects the water passage chamber 160 and the water passage 170. Thus, the water flow from the water inlet channel 121 can enter the water passage chamber 160 through the inclined water holes 1151 and impact the driving member 331.
[0120] In some embodiments, the annular plate 115 may not have a water outlet hole 1152, and a water passage 170 may be directly provided on the wall of the water passage cavity 160 to connect the water passage cavity 160 and the water outlet cavity 150.
[0121] It is understandable that the driving component 331 can be an impeller that is driven and connected to the drive shaft 332. Alternatively, the driving component 331 can include a hydroelectric generator and a motor. The water flow impacts the hydroelectric generator to generate electrical energy, and the hydroelectric generator releases electrical energy to control the driving component 331 to continue moving only when the water flow no longer enters the shower head 1000. At this time, the pump chamber 320 will be driven to deform.
[0122] refer to Figure 2-3 In some specific embodiments of the present invention, the first housing 100 further includes a water outlet cover 140, and a water outlet channel 141 is disposed on the water outlet cover 140. Specifically, the water outlet channel 141 can be a water outlet nozzle disposed on the water outlet cover 140, and the water outlet channel 141 connects the water outlet cavity 150 and the outside. (See reference) Figure 2 , 3 When the second housing 200 is disposed within the first housing 100, the first cover 210 is close to the water outlet cover 140, and the second cover 230 faces away from the water outlet cover 140. Therefore, the water outlet cover 140 and the first cover 210 together form a water outlet cavity 150. Through the air vent 211 disposed on the first cover 210, gas in the air intake cavity 240 can enter the water outlet cavity 150. A third one-way component 130 is disposed between the water passage cavity 160 and the water outlet cavity 150, so that fluid can only enter the water outlet cavity 150 from the water passage cavity 160 in one direction.
[0123] Because the water passage chamber 160 and the water outlet chamber 150 are connected by the water passage channel 170, and when gas enters the water outlet chamber 150, no water flow enters the shower head 1000, the gas entering the water outlet chamber 150 may be discharged from the water inlet channel 121 through the water passage channel 170, resulting in poor or even no pressurization effect in the water outlet chamber 150, leading to poor drainage. It is also possible that when the air pressure in the water outlet chamber 150 increases, some water flow may enter the water passage channel 170 due to the pressure. When the air intake device 300 stops adding gas to the water outlet chamber 150, the water flow in the water passage channel 170 flows back into the water outlet chamber 150, resulting in residual water not being completely drained.
[0124] In this embodiment, by setting a third one-way component 130, while ensuring that the water flow in the water passage 160 can smoothly enter the water outlet 150, the problem of poor drainage effect caused by the water flow or gas in the water outlet 150 entering the water passage 170 can be avoided.
[0125] Specifically, the third one-way component 130 can be a one-way valve, a check valve, or a plate or membrane that can only be folded in one direction.
[0126] refer to Figure 2-3 9, 11-12. In some specific embodiments of the present invention, the driving member 331 includes a rotating shaft 3311, which is hollow and has a rotating shaft hole 3312 extending along its axial direction. A first shaft segment 3321 is partially inserted into the rotating shaft hole 3312. Specifically, the portion of the first shaft segment 3321 outside the air intake chamber 240 is inserted into the rotating shaft hole 3312, and the first shaft segment 3321 can rotate relative to the rotating shaft hole 3312.
[0127] The shower head 1000 also includes an energy storage device, which includes an energy storage component 400 and a transmission component 500. The energy storage component 400 is driven to the rotating shaft 3311, and the transmission component 500 is at least partially inserted in the rotating shaft hole 3312 and driven to the first shaft segment 3321. The transmission component 500 also has a first state in which it can rotate relative to the rotating shaft hole 3312 and a second state in which it is driven to the rotating shaft hole 3312.
[0128] When water flows into the water passage chamber 160, the drive component 331 is impacted and rotates in the first direction. During the rotation, the energy storage component 400 stores energy using the kinetic energy of the water flow. At this time, the transmission component 500 is in the first state. Therefore, the rotating shaft 3311 does not drive the transmission component 500 and the drive shaft 332 to rotate, so no gas enters the outlet chamber 150. When the shower head 1000 is used up and there is no water flow in the water passage chamber 160, the energy stored in the energy storage component 400 is converted into kinetic energy and causes the drive component 331 to rotate in the second direction. At this time, the transmission component 500 is in the second state. Therefore, the transmission component 500 is driven by the rotating shaft 3311 to rotate in the second direction, thereby driving the drive shaft 332 to rotate and driving the drive disc 333 to move. Thus, when there is no water flow in the water passage chamber 160 after use, the bowl 311 inputs gas into the outlet chamber 150 to discharge residual water.
[0129] Therefore, by selectively driving the drive component 331 through the energy storage component 400, the shower head 1000 can be used without inflating and draining the water outlet chamber 150, and only draining water when the shower head 1000 is turned off, which better meets the user's needs and utilizes the kinetic energy of water flow as an energy source to achieve energy saving and consumption reduction.
[0130] It is understandable that one of the first direction and the second direction is clockwise, and the other is counterclockwise.
[0131] It is understood that the energy storage component 400 may include a hydroelectric generator, an energy storage mechanism, and a motor. The motor is connected to the transmission component 500. When the water flow impacts the drive component 331, the hydroelectric generator rotates to generate electricity and uses the energy storage mechanism to store electrical energy. When the shower head 1000 is finished using, the energy storage mechanism uses its electrical energy to drive the motor to rotate the transmission component 500, thereby realizing the function of removing residual water.
[0132] It is understandable that the position of the transmission component 500 can be changed by driving the motor, thereby switching the transmission component 500 between the first and second states. Alternatively, the transmission component 500 can be set as a magnet, and a magnetic attraction module can be set in the shower head 1000 to change the position of the transmission component 500; no specific limitation is made here.
[0133] refer to Figure 2 , 10 12. In some specific embodiments of the present invention, the first housing 100 further includes a receiving cavity 116, which is disposed on the side of the water passage cavity 160 facing away from the second housing 200. The energy storage component 400 is disposed in the receiving cavity 116. A connecting hole 1141 is provided between the receiving cavity 116 and the water passage cavity 160. The rotating shaft 3311 passes through the connecting hole 1141 at least partially into the receiving cavity 116, and the rotating shaft 3311 can rotate relative to the connecting hole 1141.
[0134] According to an embodiment of the present invention, the energy storage component 400 and the drive component 331 are each provided with corresponding accommodating spaces, which avoids mutual interference and makes more reasonable allocation and use of the space inside the shower head 1000.
[0135] refer to Figure 2-3 10. In some specific embodiments of the present invention, the first housing 100 includes an outer shell 110 and a water inlet pipe 120. The water inlet pipe 120 is provided with a water inlet channel 121. The outer shell 110 includes a mounting part 112, a hollow handle 111, and a back cover 113. The mounting part 112 is a frame that runs through both sides. The water outlet cover 140 and the back cover 113 are respectively disposed on the two sides of the mounting part 112 and enclose a space that communicates with the inside of the handle 111. The water inlet pipe 120 passes through the handle 111. The second housing 200 is disposed in the outer shell 110.
[0136] The outer casing 110 also includes a second partition plate 114. Specifically, the second partition plate 114 is arranged radially along the mounting portion 112. The second partition plate 114 is located on the side of the second cover 230 facing away from the air outlet 211, and an annular plate 115 extends from the side of the second partition plate 114 near the second cover 230. Thus, the second partition plate 114 and the second cover 230 form a water passage cavity 160.
[0137] refer to Figure 2 , 3 In some embodiments, 10, 12, the second partition plate 114 is specifically disposed between the second housing 200 and the back cover 113, and the second partition plate 114 and the back cover 113 also form an accommodating cavity 116. A connecting hole 1141 is disposed on the second partition plate 114 and penetrates the second partition plate 114, and the first cover 210 and the water outlet cover 140 form a water outlet cavity 150.
[0138] refer to Figure 11 , 12 In some specific embodiments of the present invention, the driving component 331 is an impeller, including a rotating shaft 3311 and a plurality of blades 3316, wherein the blades 3316 and the inner wall of the water passage cavity 160 are in clearance fit, and water can flow in the gap.
[0139] refer to Figure 2 , 311-13. The energy storage component 400 includes a torsion spring 410 and a sleeve 420. One end of the torsion spring 410 is fixed to the outer peripheral wall of the sleeve 420, and the other end is fixed to the first housing 100. A second connecting part 421 is provided on the inner peripheral wall of the sleeve 420. A third connecting part 3314 is provided on the outer peripheral wall of the part of the rotating shaft 3311 that passes through the accommodating cavity 116. The sleeve 420 is sleeved on the rotating shaft 3311. The second connecting part 421 and the third connecting part 3314 cooperate to drive the connection between the sleeve 420 and the rotating shaft 3311.
[0140] According to an embodiment of the present invention, when water flows into the water passage chamber 160 and impacts the impeller to rotate (assuming clockwise), due to the driving connection between the rotating shaft 3311 and the sleeve 420, the rotating shaft 3311 drives the sleeve 420 to rotate. Since one end of the torsion spring 410 is fixedly connected to the outer peripheral wall of the sleeve 420 and the other end is fixedly connected to the first housing 100 of the shower head 1000, at this time, one end of the torsion spring 410 will be driven by the sleeve 420 to twist and deform, and the kinetic energy of the water flow is converted into the elastic potential energy of the torsion spring 410 and stored in the torsion spring 410. Furthermore, as the torsion spring 410 continues to twist and deform, the circumferential force exerted by the torsion spring 410 on the sleeve 420 also increases until the force exerted by the torsion spring 410 on the sleeve 420 equals the impact force of the water flow on the impeller. At this point, the impeller stops rotating, the torsion spring 410 no longer deforms, and during this process, no gas enters the water outlet chamber 150. At this time, the water flows through the gap between the blade 3316 and the inner wall of the water passage chamber 160 to the water outlet. When the shower head 1000 is finished using, the user turns off the water inlet of the shower head 1000. At this time, the impeller is no longer impacted by the water flow. At this time, the torsion spring 410 begins to return to its shape and drives the sleeve 420 and the impeller to rotate (in a counterclockwise direction), thereby driving the bowl 311 to output gas to the air outlet 211.
[0141] It is understandable that one of the second connecting part 421 and the third connecting part 3314 can be a locking block, and the other can be a locking groove. Alternatively, both the second connecting part 421 and the third connecting part 3314 can be adhesive or welded parts. This is not limited here, as long as the drive connection between the sleeve 420 and the rotating shaft 3311 can be achieved.
[0142] refer to Figure 2 In some embodiments, a fourth connecting portion 1142 is provided on the side of the second partition plate 114 near the back cover 113. One end of the torsion spring 410 is fixedly connected to the outer peripheral wall of the sleeve 420, and the other end is fixedly connected to the fourth connecting portion 1142. Specifically, the fourth connecting portion 1142 may be a protrusion, and one end of the torsion spring 410 is fixedly connected to the protrusion.
[0143] refer to Figure 9 , 1112, 14. In some specific embodiments of the present invention, the transmission assembly 500 includes a transmission member 510, which is at least partially inserted into the shaft hole 3312. A transmission shaft 512 is provided on one end of the transmission member 510 near the first shaft segment 3321, and a third shaft hole 3322 is provided on one end of the first shaft segment 3321 near the transmission member 510. The transmission member 510 and the first shaft segment 3321 are connected by the transmission shaft 512 and the third shaft hole 3322. A first limiting member 511 is provided on the outer peripheral wall of the transmission member 510, and a second limiting member 3315 is provided on the inner peripheral wall of the shaft hole 3312.
[0144] When the first limiting member 511 and the second limiting member 3315 are connected to each other, the transmission assembly 500 is in the second state, that is, the transmission assembly 500 and the rotating shaft hole 3312 are driven connected. When the first limiting member 511 and the second limiting member 3315 are disengaged from each other, the transmission assembly 500 is in the first state, that is, the transmission assembly 500 can rotate relative to the rotating shaft hole 3312.
[0145] It is understandable that the first limiting member 511 and the second limiting member 3315 can both be magnetic, and the magnetic properties of the first limiting member 511 and the second limiting member 3315 are opposite. When the first limiting member 511 and the second limiting member 3315 are opposite, they attract each other through magnetic force, thereby realizing the driving connection. At this time, the transmission assembly 500 is in the second state. When the first limiting member 511 and the second limiting member 3315 are misaligned, the transmission assembly 500 is in the first state, and the transmission member 510 can rotate relative to the rotating shaft hole 3312.
[0146] Alternatively, one of the first limiting member 511 and the second limiting member 3315 can be a limiting block, and the other can be a limiting groove. When the transmission assembly 500 is in the first state, the limiting block and the limiting groove are disengaged from each other. When the transmission assembly 500 is in the second state, the limiting block and the limiting groove are engaged with each other.
[0147] Alternatively, the first limiting member 511 and the second limiting member 3315 may be designed with a ballpoint pen rotation structure to achieve either a disengaged state or a locked state.
[0148] It is understandable that the state of the transmission component 500 can be changed by the motor. For example, when the transmission component 500 needs to be in the first state, the motor can drive the transmission component 500 to move and disengage the first limiting member 511 and the second limiting member 3315 from each other. Otherwise, the transmission component 500 is driven to connect the first limiting member 511 and the second limiting member 3315 to each other.
[0149] refer to Figure 11 , 12In some specific embodiments of the present invention, a water channel 3313 is provided at one end of the shaft hole 3312 facing away from the energy storage component 400. Specifically, it can be a groove obtained by hollowing out the inner wall of the shaft hole 3312, or it can be a groove formed by the space between any two adjacent second limiting members 3315. The water channel 3313 connects the water cavity 160 and the shaft hole 3312. When the transmission member 510 and the drive shaft 332 are inserted into the shaft hole 3312, the water flow in the water cavity 160 can enter the shaft hole 3312 from the water channel 3313, and use the water pressure or buoyancy to push the transmission member 510 away from the water channel 3313, thereby causing the first limiting member 511 and the second limiting member 3315 to disengage from each other. That is, when the shower head 1000 takes in water, although it can drive the impeller to rotate and drive the energy storage component 400 to store energy, there is no transmission between the transmission component 510 and the shaft hole 3312. Therefore, the transmission component 510 does not rotate, and consequently the drive shaft 332 does not rotate, and the air intake device 300 does not supply air to the air outlet 211.
[0150] When the shower head 1000 is finished, no water flows into the shower head 1000, and no water flows into the rotating shaft hole 3312. At this time, the transmission component 510 is reset, and the first limiting component 511 and the second limiting component 3315 are connected to each other. At this time, when the torsion spring 410 drives the rotating shaft 3311 to rotate, it also drives the drive shaft 332 to rotate through the transmission component 510, and uses the bowl 311 to output gas to the water outlet chamber 150 to discharge residual water.
[0151] It is understandable that the reset of the transmission component 510 can be achieved in a variety of ways. When the water pressure or buoyancy is lost, the transmission component 510 can reset by its own weight, or the user can swing the shower head 1000 to reset the transmission component 510 under inertia.
[0152] refer to Figure 12 In some specific embodiments of the present invention, the transmission assembly 500 further includes an elastic element 520, which may be a spring or other structural component capable of elastic deformation. One end of the elastic element 520 abuts against the end of the transmission component 510 facing away from the drive shaft 332, and the other end abuts against the bottom wall of the sleeve 420. When no water flows into the rotating shaft hole 3312 (initially no water flows in or the water inlet is closed after the shower head 1000 is used), the elastic element 520 provides elastic force to the transmission component 510 to connect the first limiting member 511 and the second limiting member 3315.
[0153] According to the embodiments of this application, the initial interconnection state of the first limiting member 511 and the second limiting member 3315, as well as the reset process of the transmission member 510 after the shower head 1000 has been used, can all be achieved by the elastic member 520.
[0154] refer to Figure 12 , 13 In some specific embodiments of the present invention, a pressure relief hole 422 is also provided on the bottom wall of the sleeve 420. Specifically, the pressure relief hole 422 penetrates the bottom wall of the sleeve 420 and connects the inside of the sleeve 420 with the accommodating cavity 116. Thus, when the transmission member 510 moves, the air pressure inside the sleeve 420 can be balanced, and there will be no pressure buildup that would affect the movement of the transmission member 510.
