Description

Technical Field

[0001] The present invention relates to the field of shower heads, and in particular to a shower head. Background Art

[0002] After using a showerhead, residual water can easily grow bacteria or form scale, clogging the nozzle, thus affecting its proper function. In some existing technologies, after the showerhead stops discharging water, the outlet chamber is connected to the outside world to balance the pressure inside and outside the showerhead, allowing the remaining water in the outlet chamber to drain under its own gravity. However, since this drainage process relies solely on the water's own weight, it is slow. Furthermore, because the outlet nozzle's cross-sectional area is often relatively small, the water tension within the nozzle can easily prevent subsequent water flow from draining smoothly, resulting in a problem with the remaining water being completely drained.

DETAILED DESCRIPTION

[0033] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0034] refer to Figure 1 In some specific embodiments of the present invention, a shower head 1000 is provided that can utilize gas from an external air source to drive the removal of residual water that cannot be discharged after the water flow stops, thereby avoiding dripping, residual water breeding bacteria, etc. It is particularly noted here that the "external air source" referred to here and in the following content can be the external environment, or it can be a gas supply device such as a gas cylinder outside the shower head 1000. refer to Figure 1-3 The showerhead 1000 provided in this embodiment includes a first housing 100 and an air suction device 300. The first housing 100 includes a water inlet channel 121, a water outlet chamber 150, and a water outlet channel 141, arranged in sequence. Water can flow from the water inlet channel 121 into the water outlet chamber 150 and be discharged from the water outlet channel 141 for use. An air suction chamber 240 is also provided in the first housing 100. The wall of the air suction chamber 240 is provided with at least one air outlet hole 211, which penetrates the wall of the air suction chamber 240. Gas in the air suction chamber 240 can enter the water outlet chamber 150 through the air outlet hole 211, thereby increasing the air pressure in the water outlet chamber 150 and squeezing any residual water in the water outlet chamber 150 out of the water outlet channel 141, thereby preventing dripping, bacterial growth, and the like.

[0035] The air suction device 300 is disposed in the air suction chamber 240 , and includes a piston membrane assembly 310 , a first one-way member 340 and a drive assembly 330 .

[0036] The piston diaphragm assembly 310 is disposed in the suction chamber 240 and includes at least one bowl portion 311. The bowl portion 311 opens toward the air outlet 211. The bowl portion 311 and the inner wall of the suction chamber 240 enclose a pump chamber 320. The air inlet end of the air outlet 211 communicates with the pump chamber 320. As a result, when the volume of the pump chamber 320 decreases, the gas in the pump chamber 320 can be driven out of the air outlet 211. A first one-way member 340 is disposed on the air outlet 211 to control the gas in the pump chamber 320 to unidirectionally exit the pump chamber 320 through the air outlet 211. The driving assembly 330 is driven and connected to the bowl portion 311. When the driving assembly 330 moves, the bowl portion 311 can be controlled to move and / or deform, thereby changing the volume of the pump chamber 320. At this time, the driving assembly 330 and the bowl portion 311 are equivalent to an "air pump". During the operation of the "air pump", when the volume of the pump chamber 320 becomes smaller, the gas in the pump chamber 320 can leave the pump chamber 320 from the air outlet 211.

[0037] It is understood that when showerhead 1000 is in normal use and water flows into showerhead 1000, the gas in pump chamber 320 does not enter water outlet chamber 150 to avoid affecting water flow. Only when there is no water flowing into showerhead 1000, that is, when showerhead 1000 is no longer in use, does the gas enter water outlet chamber 150 to drain the remaining water.

[0038] refer to Figure 2-3 In some specific embodiments, the outlet end of the air outlet hole 211 can be directly connected to the water outlet chamber 150. In this case, when water flows into the showerhead 1000, the driving assembly 330 does not control the movement and / or deformation of the bowl 311, and no gas enters the water outlet chamber 150. When the showerhead 1000 is no longer in use and no water flows into the showerhead 1000, the driving assembly 330 can drive the bowl 311 to move and / or deform, thereby allowing gas to enter the water outlet chamber 150. For example, the driving assembly 330 may include a processor, a hydroelectric power generation device, a power storage device, and a transmission mechanism. When water flows into the showerhead 1000, the hydroelectric power generation device is activated and generates electricity, which is stored in the power storage device. According to a program preset in the processor, when the power storage device no longer receives electricity from the hydroelectric power generation device (i.e., when the showerhead 1000 is no longer in use and no water flows into the showerhead 1000), 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 includes a deformable and restorable elastic mechanism. When water flows into the shower head 1000, the elastic mechanism deforms and stores energy. After the shower head 1000 is used, the elastic mechanism restores its shape and drives the bowl 311 to move and / or deform.

[0039] According to the specific embodiment provided by the present invention, after the shower head 1000 is used (when no water flows into it), gas can be sent into the water outlet chamber 150, thereby increasing the air pressure in the water outlet chamber 150 and draining the residual water in the water outlet chamber 150, thereby avoiding problems such as dripping or residual water breeding bacteria after the shower head 1000 is turned off.

[0040] It is understandable that the driving component 330 may also be other power devices that can achieve a driving effect, which is not specifically limited here.

[0041] It can be understood that the first one-way member 340 can be a one-way valve, a check valve, etc., which is fixedly arranged on the air outlet 211, or it can be a structure with a membrane. Specifically, the area of ​​the membrane is larger than the air passing cross-sectional area of ​​the air outlet 211. The position and area setting of the membrane limit the membrane to deform only along the side facing away from the air outlet 211, thereby exposing the air outlet end of the air outlet 211.

[0042] 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 cavity 240. Specifically, the second housing 200 can be a portion of the first housing 100, integrally formed with the first housing 100, or a separate housing structure assembled within the first housing 100. The air outlet 211 is provided on a wall of the second housing 200.

[0043] refer to Figure 4 In some specific embodiments of the present invention, the second shell 200 includes a cylindrical portion 220, which is radially provided with a first partition plate 221. A cylinder 222 is provided on the first partition plate 221. Specifically, the cylinder 222 extends in a direction away from the air outlet 211, is hollow, and is in communication with the air outlet 211. Specifically, the end of the cylinder 222 near the air outlet 211 can be completely hollowed out, in which case the end of the air outlet 211 is directly in communication with the space within the cylinder 222. Alternatively, the end of the cylinder 222 near the air outlet 211 is still blocked by the first partition plate 221, and an opening is provided on the first partition plate 221 enclosed in the cylinder 222, which passes through the first partition plate 221. The opening is provided corresponding to the air outlet 211, thereby connecting the air outlet 211 with the space within the cylinder 222.

[0044] The bowl portion 311 is slidably disposed in the cylinder 222 , and the outer peripheral wall of the bowl portion 311 is sealed against the inner wall of the cylinder 222 .

[0045] It is understandable that when the end of the cylinder 222 close to the air outlet 211 is completely hollowed out, the bowl portion 311 , the cylinder 222 and the wall surface of the second shell 200 enclose a pump chamber 320 .

[0046] As a result, when the bowl portion 311 is driven to slide back and forth within the cylinder 222, the volume of the pump chamber 320 changes, thereby completing the inflation process. It is understood that if the bowl portion 311 is made of a deformable material such as rubber, once the bowl portion 311 abuts the first partition plate 221, it can continue to deform toward the air outlet 211, thereby transferring the gas within the bowl portion 311 into the air outlet 211.

[0047] refer to Figure 3 、 4 In some specific embodiments of the present invention, an air inlet channel 250 is further provided on the first shell 100, and the air inlet channel 250 connects the air suction cavity 240 with an external air source.

[0048] The air inlet channel 250 can be provided on the second housing 200. Specifically, the air inlet channel 250 can be a gas channel provided on the second housing 200, connecting the air inlet chamber 240 with an external air source. The air inlet channel 250 can also be an opening on the second housing 200, connecting the air inlet chamber 240 with the interior space of the showerhead 1000 outside the second housing 200. The interior space of the showerhead 1000 is connected to the external air source, thereby allowing air to enter the air inlet chamber 240 through the air inlet channel 250.

[0049] In some specific embodiments of the present invention, the shower head 1000 is further provided with an air supply channel. When the air suction device 300 continuously inflates the air outlet 211, the volume of the pump chamber 320 continuously cycles in a process of "shrinking-restoring". The air supply channel is used to input gas into the pump chamber 320 during the recovery process to maintain the pressure balance inside and outside the pump chamber 320 and ensure that there is sufficient gas in the pump chamber 320 during the next inflation.

[0050] Specifically, one end of the air supply channel is communicated with the pump chamber 320 , and the other end is communicated with the air suction chamber 240 , so that the gas in the air suction chamber 240 can enter the pump chamber 320 through the air supply channel.

[0051] In some embodiments, a supplemental gas channel can be provided on the bowl portion 311 (not shown). Specifically, the supplemental gas channel extends through the circumferential wall of the bowl portion 311. In this embodiment, the supplemental gas channel can be designed to have a very small cross-sectional area, and a first one-way member 340 (such as a check valve) can be selected that only requires a relatively low pressure to open in one direction. Consequently, when the pump chamber 320 contracts, the vast majority of gas enters the gas outlet 211, leaving only a minimal amount of gas to enter the suction chamber 240 via the supplemental gas channel, thus negligibly affecting the inflation process. When the pump chamber 320 is restored, the first one-way member 340 seals the gas outlet 211, allowing only gas in the suction chamber 240 to enter the pump chamber 320 via the supplemental gas channel.

[0052] In some specific embodiments of the present invention, the shower head 1000 is further provided with a second one-way member. Specifically, the second one-way member is provided on the air supply channel to control the gas in the suction chamber 240 to enter the pump chamber 320 in one direction.

[0053] In this embodiment, due to the provision of a second one-way member, when the pump chamber 320 inflates the air outlet 211, the gas cannot enter the air intake chamber 240 from the air supply channel. Therefore, at this time, the air flow cross-sectional area of ​​the air supply channel no longer needs to be limited to a certain range, and the air flow cross-sectional area can be appropriately increased to increase the speed of air supply.

[0054] It is understandable that the second one-way member can be a check valve, a stop valve, etc., or a foldable diaphragm 314, and the diaphragm 314 can only be folded back and forth along the air supply direction to open and close the air supply channel.

[0055] refer to Figure 3 In some specific embodiments of the present invention, the second shell 200 includes a first cover assembly and a second cover 230, wherein the air outlet 211 and the air supply channel are provided on the first cover assembly.

[0056] It is understandable that the air supply channel can also be designed with a suitable air flow cross-sectional area to meet the air supply demand.

[0057] 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 barrel 220. The barrel 220 is hollow, and its two ends are connected to the first cover 210 and the second cover 230, respectively. The first cover 210 is provided with an air outlet hole 211 and an air supply groove 212. Specifically, the air outlet hole 211 passes through the first cover 210. The air supply groove 212 is hollowed out on the side of the first cover 210 facing away from the air outlet end of the air outlet hole 211 (not passing through the first cover 210). The barrel 220 extends along its own radial direction to form a first partition plate 221. The air supply hole 2211 is provided on the first partition plate 221 and passes through the first partition plate 221.

[0058] Among them, the pump chamber 320, the air-supply groove 212 and the air-supply hole 2211 are arranged in sequence, and 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 hole 211 and then recovers, the gas in the air-supply chamber 240 can pass through the air-supply hole 2211 and the air-supply groove 212 in turn and then enter the pump chamber 320.

[0059] refer to Figure 2 、 6In some specific embodiments of the present invention, the bowl portion 311 is at least partially constructed of a deformable material. A membrane portion 312 is disposed on the open side of the bowl portion 311, and the membrane portion 312 is clamped between the first cover 210 and the barrel 220. In this case, the bowl portion 311 is essentially buckled onto the first cover 210, and together with the first cover 210, it encloses the pump chamber 320. It will be understood that 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 axis of the barrel 220.

[0060] According to an embodiment of the present invention, at this time, the bowl portion 311 has been clamped in place because the membrane portion 312 on its open side has been clamped. When the drive component 330 applies force to the bowl portion 311 in a direction close to the air outlet 211, the bowl portion 311 only deforms but does not move, and the volume of the pump chamber 320 shrinks to complete inflation. When the drive component 330 applies force in a 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 air supply channel.

[0061] refer to Figure 2 、 4 6. In some specific embodiments of the present invention, the first partition plate 221 further includes a cylinder 222. Specifically, the cylinder 222 extends in a 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 312 of the bowl 311 is clamped. At this time, the bowl 311 is deformed in the cylinder 222, thereby changing the volume of the pump chamber 320. This prevents the bowl 311 from deflecting during the deformation process and interfering with other structural components in the shower head 1000, thereby affecting the inflation and air replenishment effects.

[0062] In some embodiments (not shown), the piston membrane assembly 310 may have only one bowl portion 311 , and the driving assembly 330 is only drivingly connected to the bowl portion 311 , and the inflation process is completed through the bowl portion 311 .

[0063] In some embodiments, the piston membrane assembly 310 is composed of a plurality of bowls 311, and the driving assembly 330 is simultaneously 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 a variety of different methods. For example, the driving assembly 330 drives the plurality of bowls 311 to move in one direction at the same time, so that the plurality of bowls 311 are inflated or replenished with air at the same time, or the driving direction of at least one of the plurality of bowls 311 is opposite to that of the other bowls 311. For example, the driving directions of any two adjacent bowls 311 can be different, or the plurality of bowls 311 can be arranged in an array along a circle, a square, etc., and the plurality of bowls 311 complete the inflation and replenishment process in sequence along a certain direction of the array and continuously circulate.

[0064] refer to Figure 6 In some specific embodiments of the present invention, the piston membrane assembly 310 is provided with N bowl portions 311, where N is an integer greater than or equal to 2, and can be 3, 4, or more. The N bowl portions 311 are connected by a membrane portion 312, and the membrane portions 312 on each bowl portion 311 can be connected to each other to form a membrane-like structure with a larger area. The N bowl portions 311 are arranged in the membrane portion 312, and the number of cylinders 222 is the same as the number of bowl portions 311. Specifically, the membrane portion 312 provided with the N bowl portions 311 is provided on the side of the first partition plate 221 close to the first cover body 210, and the skirt of the membrane portion 312 is clamped between the cylinder portion 220 and the first cover body 210. The N bowl portions 311 are provided in a one-to-one correspondence with the N cylinders 222.

[0065] It can be understood that at this time, the first cover body 210 also has N air outlet holes 211 and air supply grooves 212, and the first partition plate 221 is provided with N air supply holes 2211. Thus, under the action of the driving component 330, each bowl portion 311 can complete the inflation and air supply process in the corresponding cylinder 222.

[0066] refer to Figure 6 、 7 In some specific embodiments of the present invention, vent holes 313 are provided in the membrane portion 312 corresponding to the gas-supply holes 2211, thereby preventing the membrane portion 312 from blocking the flow of gas between the gas-supply holes 2211 and the gas-supply groove 212. The vent holes 313 can be configured with a larger aperture to encompass all N gas-supply holes 2211. Alternatively, the vent holes 313 can be configured as N smaller apertures, corresponding one-to-one to each gas-supply hole 2211.

[0067] In some specific embodiments of the present invention, the second one-way member is disposed in the vent hole 313 .

[0068] Specifically, the second one-way member can be a one-way valve, a check valve, or a plate or membrane that can be folded only in one direction, as long as the gas can enter the pump chamber 320 from the gas supply channel in one direction.

[0069] refer to Figure 6 、 7In some specific embodiments of the present invention, the second one-way member includes a diaphragm 314 and a first connecting portion 315 arranged on the outer edge of the diaphragm 314. The diaphragm 314 is arranged in the vent hole 313 and is connected to the vent hole 313 or the air-replenishing hole 2211 through the first connecting portion 315. When the diaphragm 314 is connected to the air-replenishing hole 2211, the specific position of the diaphragm 314 is on the side of the air-replenishing hole 2211 close to the air-replenishing groove 212. Specifically, the area of ​​the diaphragm 314 is larger than the air-passing cross-sectional area of ​​the vent hole 313 or the air-replenishing hole 2211. The first connecting portion 315 is arranged 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 hole 313 or the air-replenishing hole 2211, the diaphragm 314 can be folded with the first connecting portion 315 as the axis.

[0070] In the embodiment of the present invention, when gas enters the air supply channel from the suction 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 air supply hole 2211. When gas enters the air supply groove 212 from the pump chamber 320, the diaphragm 314 is driven by the gas to cover the vent 313 or the air supply hole 2211, cutting off the connection between the air supply groove 212 and the air supply hole 2211, and the gas cannot enter the suction chamber 240, thereby limiting the flow direction of the gas.

[0071] It can be understood that the diaphragm 314 is a part of the membrane portion 312, and an arc-shaped incision can be set on the membrane portion 312. The part of the membrane portion 312 surrounded by the incision is the diaphragm 314. It only needs to set the appropriate arc shape and size so that the diaphragm 314 can be folded.

[0072] refer to Figure 2 、 3 In some specific embodiments of the present invention, the driving assembly 330 includes a driving member 331, a driving shaft 332 and a driving disk 333. The driving disk 333 is driven and connected to the bowl 311. The driving member 331 and the driving disk 333 are respectively arranged at both ends of the driving shaft 332. Thus, the driving member 331 can use the driving shaft 332 to move the driving disk 333, thereby controlling the movement and / or deformation of the bowl 311.

[0073] It is understandable that the drive assembly 330 can be disposed as a whole in the suction cavity 240, or the drive member 331 can be disposed outside the suction cavity 240 (still in the shower head 1000), the drive disc 333 is disposed in the suction cavity 240, and the drive shaft 332 passes through the second shell 200 to connect the two.

[0074] It is understood that the drive member 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 member 331 may be directly connected to a power supply, or it may be connected to a hydroelectric power generation device, using the water discharged by the shower head 1000 to power the motor.

[0075] It is understandable that the driving member 331 can also be an impeller, a turbine, etc. The driving assembly 330 is arranged in the suction chamber 240 where water flows through. The water flow impacts the driving member 331 to rotate. At this time, the driving member 331 does not control the movement of the driving disk 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 used up and no water flows in, the energy storage device releases energy and causes the driving disk 333 to reciprocate along the axial direction of the drive shaft 332.

[0076] refer to Figure 6 、 8 In some specific embodiments of the present invention, the drive disk 333 is provided with N first hinges 3331, and a second hinge 316 is provided on the side of the bowl 311 facing away from the pump chamber 320. The drive disk 333 and the bowl 311 are connected in a one-to-one correspondence via the first hinges 3331 and the second hinges 316. The first hinges 3331 are arranged in a circular array on the outer edge of the drive disk 333, centered at the junction of the drive disk 333 and the drive shaft 332.

[0077] Specifically, one of the first hinge 3331 and the second hinge 316 can be an annular sleeve, and the other can be a ball head. The annular sleeve can be mounted on the ball head to achieve driving. The first hinge 3331 and the second hinge 316 can also be configured as buckles or other connecting structures, as long as they can achieve the connection function, which is not specifically limited here.

[0078] refer to Figure 8 In some specific embodiments of the present invention, the driving disk 333 is bowl-shaped and its opening faces away from the piston membrane assembly 310 .

[0079] In a specific embodiment of the present invention, the bowl-shaped design of the driving disk 333 is compared to the flat-plate-shaped driving disk 333. In the initial state, the distance between the driving disk 333 and the air outlet 211 is larger, and when the driving disk 333 moves toward the back of the air outlet 211, the other side of the driving disk 333 also has a larger stroke before moving to interfere with the inner wall of the suction chamber 240. Therefore, the bowl 311 travels farther during the air replenishment process. Therefore, 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, and more gas can be inhaled to be input into the air outlet 211, making the inflation process faster and more efficient.

[0080] refer to Figure 2-3 8-9, in some specific embodiments of the present invention, the second cover body 230 is provided with a first axial hole 231, the axis of the first axial hole 231 is parallel to the axis of the cylinder 220, and the drive shaft 332 is passed through the first axial hole 231. Specifically, the drive shaft 332 includes a first shaft segment 3321 and a second shaft segment 3323, wherein the angle β between the first shaft segment 3321 and the second shaft segment 3323 is an obtuse angle, and the first shaft segment 3321 is partially passed through the first axial hole 231. At this time, the second The shaft section 3323 is located in the suction chamber 240. The portion of the first shaft section 3321 facing away from the second shaft section 3323 is located outside the suction chamber 240 and is connected to the driving member 331 so as to be driven to rotate by the driving member 331. The driving disk 333 is arranged in the suction chamber 240 and is pivotally connected to the second shaft section 3323. Specifically, the driving disk 333 is roughly disc-shaped, and a second shaft hole 3332 is provided in the middle of the driving disk 333. The second shaft section 3323 is passed through the second shaft hole 3332 to complete the pivot connection.

[0081] Specifically, the driving member 331 can be configured as a motor that rotates the driving shaft 332 , or it can be an impeller. When the impeller rotates due to the impact of the water flow, the driving shaft 332 rotates accordingly.

[0082] In the embodiment of the present invention, when the shower head 1000 is in the initial state, due to the inclined design of the second shaft segment 3323, the driving disc 333 is also tilted relative to the first shaft segment 3321, that is, one side of the driving disc 333 is relatively close to the driving member 331, and the other side is relatively close to the air outlet 211. The bowl portion 311 on one side is stretched while the bowl portion 311 on the other side is compressed and folded. When the driving member 331 rotates the driving shaft 332, 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 driving disc 333 are pivotally connected, the driving disc 333 does not rotate at this time, but reciprocates along the first hinge 3331 in the circumferential direction of the driving disc 333, thereby driving the bowl portion 311 to continuously reciprocate, thereby completing the process of inflating and replenishing air.

[0083] It is particularly pointed out here 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, at this time, even if the drive disk 333 has a slight tendency to rotate due to the friction force, the connection between the first hinge 3331 and the second hinge 316 can overcome this friction force and prevent the drive disk 333 from rotating.

[0084] refer to Figure 2 In some specific embodiments of the present invention, the first shell 100 further includes a water passage chamber 160, which is disposed between the water inlet channel 121 and the water outlet chamber 150. The water in the water inlet channel 121 can flow through the water chamber 160 and then flow into the water outlet chamber 150. The driving member 331 is disposed in the water passage chamber 160. When the water flows through the water passage chamber 160 and impacts the driving member 331, the driving member 331 can be caused to rotate.

[0085] It is particularly pointed out here that the driving member 331 can use the energy storage device to convert and store the kinetic energy of the water flow during the water flow impact movement, and does not control the deformation of the pump chamber 320. Moreover, when the water flow stops entering the shower head 1000, the energy storage device releases energy and causes the driving member 331 to be in motion for a period of time, at which time the deformation of the pump chamber 320 is controlled.

[0086] refer to Figure 2 In some embodiments, the water passage chamber 160 and the water outlet chamber 150 are connected via a water passage 170 .

[0087] refer to Figure 2 、 10In some specific embodiments of the present invention, an annular plate 115 is provided on a side of the first shell 100 close to the second cover body 230 or on a side of the second cover body 230 facing away from the suction chamber 240. By providing the annular plate 115, a water flow chamber 160 is enclosed between the second cover body 230 and the first shell 100. A water outlet hole 1152 and a plurality of inclined water holes 1151 are provided on the annular plate 115. The inclined water holes 1151 connect the water inlet channel 121 and the water flow chamber 160, and the water outlet holes 1152 connect the water flow chamber 160 and the water flow channel 170. Thus, the water flow from the water inlet channel 121 can enter the water flow chamber 160 from the inclined water holes 1151 and impact the driving member 331.

[0088] In some embodiments, the water outlet hole 1152 may not be provided on the annular plate 115 , and a water passage 170 may be directly provided on the wall surface of the water passage cavity 160 to connect the water cavity 160 and the water outlet cavity 150 .

[0089] It is understood that the driving member 331 can be an impeller drivingly connected to the drive shaft 332. Alternatively, the driving member 331 includes a hydroelectric device and a motor. When water flows into the hydroelectric device, it generates electricity. When the water no longer flows into the shower head 1000, the hydroelectric device releases the electricity to control the driving member 331 to continue to move, at which point the pump chamber 320 is driven to deform.

[0090] 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 provided on the water outlet cover 140. Specifically, the water outlet channel 141 may be a water outlet nozzle provided on the water outlet cover 140, and the water outlet channel 141 connects the water outlet cavity 150 with the outside. Figure 2 、 3 When the second housing 200 is installed in 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 chamber 150 is enclosed between the water outlet cover 140 and the first cover 210. Through the air outlet hole 211 provided on the first cover 210, the gas in the suction chamber 240 can enter the water outlet chamber 150. A third one-way member 130 is provided between the water passage chamber 160 and the water outlet chamber 150 to prevent fluid from entering the water outlet chamber 150 from the water passage chamber 160 in a single direction.

[0091] Because the water passage chamber 160 and the water outlet chamber 150 are connected via the water passage 170, and when gas enters the water outlet chamber 150, no water is flowing into the shower head 1000. The gas that has entered the water outlet chamber 150 may be discharged from the water inlet channel 121 through the water passage 170, resulting in poor pressurization within the water outlet chamber 150, or even no pressurization at all, leading to poor drainage. It is also possible that when the air pressure within the water outlet chamber 150 increases, some water may flow into the water passage 170 due to the influence of the air pressure. When the air suction device 300 stops adding air to the water outlet chamber 150, the water in the water passage 170 may flow back into the water outlet chamber 150, making it impossible to completely drain the residual water.

[0092] In this embodiment, by providing the third one-way member 130, while ensuring that the water flow in the water chamber 160 can smoothly enter the water outlet chamber 150, it can prevent the water flow or gas in the water outlet chamber 150 from entering the water passage 170 and causing poor drainage effect.

[0093] Specifically, the third one-way member 130 may be a one-way valve, a check valve, etc., or a plate member, a membrane member, etc. that can be folded only in one direction.

[0094] 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, the rotating shaft 3311 is hollow in design, and the rotating shaft 3311 has a rotating shaft hole 3312 passing through along its axial direction, and the first shaft segment 3321 is partially inserted into the rotating shaft hole 3312. Specifically, the part of the first shaft segment 3321 located outside the suction 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.

[0095] Shower head 1000 also includes an energy storage device, which includes an energy storage assembly 400 and a transmission assembly 500. The energy storage assembly 400 is drivingly connected to the rotating shaft 3311. The transmission assembly 500 is at least partially disposed in the rotating shaft hole 3312 and is drivingly connected to the first shaft segment 3321. The transmission assembly 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 drivingly connected to the rotating shaft hole 3312.

[0096] When water enters the water passage chamber 160, the driving member 331 is impacted and rotates in a first direction. During this rotation, the energy storage assembly 400 utilizes the kinetic energy of the water flow to store energy. At this time, the transmission assembly 500 is in the first state. Therefore, the rotating shaft 3311 does not drive the transmission assembly 500 and the drive shaft 332 to rotate, and thus no gas enters the water outlet chamber 150. When the showerhead 1000 is finished using and no water flows through the water passage chamber 160, the energy stored in the energy storage assembly 400 is converted into kinetic energy, causing the driving member 331 to rotate in a second direction. At this time, the transmission assembly 500 is in the second state. Therefore, the transmission assembly 500 is driven by the rotating shaft 3311 to rotate in the second direction, thereby rotating the drive shaft 332 and driving the drive disc 333. When the water passage chamber 160 is finished using and no water flows through, the bowl 311 is used to input gas into the water outlet chamber 150 to expel any remaining water.

[0097] Therefore, by selectively driving the driving member 331 through the energy storage component 400, the water outlet chamber 150 does not need to be inflated and drained when the shower head 1000 is in use, and drainage is only performed when the shower head 1000 is turned off. This is more in line with the user's usage needs and utilizes the kinetic energy of water as an energy source to achieve energy saving and consumption reduction.

[0098] It can be understood that one of the first direction and the second direction is a clockwise direction, and the other is a counterclockwise direction.

[0099] It can be understood that the energy storage assembly 400 may include a hydroelectric generator, a power storage mechanism and a motor, and the motor is connected to the transmission assembly 500. When the water flow impacts the driving member 331, the hydroelectric generator rotates to generate electricity and uses the power storage mechanism to store electrical energy. When the shower head 1000 is used, the power storage mechanism uses its electrical energy to drive the motor to rotate the transmission assembly 500, thereby realizing the function of removing residual water.

[0100] It is understood that the position of the transmission assembly 500 can be changed by a motor, thereby switching the transmission assembly 500 between the first state and the second state. Alternatively, the transmission assembly 500 can be configured as a magnet, and a magnetic attraction module can be provided in the shower head 1000 to change the position of the transmission assembly 500. This is not specifically limited here.

[0101] refer to Figure 2 、 10 12. In some specific embodiments of the present invention, the first shell 100 further includes a accommodating chamber 116, which is disposed on a side of the water passage chamber 160 facing away from the second shell 200. The energy storage assembly 400 is disposed in the accommodating chamber 116. A connecting hole 1141 is provided between the accommodating chamber 116 and the water passage chamber 160. The rotating shaft 3311 at least partially passes through the connecting hole 1141 and enters the accommodating chamber 116, and the rotating shaft 3311 can rotate relative to the connecting hole 1141.

[0102] According to an embodiment of the present invention, the energy storage assembly 400 and the driving member 331 are each provided with corresponding accommodation spaces, which can more reasonably allocate and use the space inside the shower head 1000 while avoiding mutual interference.

[0103] refer to Figure 2-3 10. In some specific embodiments of the present invention, the first shell 100 includes an outer shell 110 and a water inlet pipe 120. A water inlet channel 121 is provided in the water inlet pipe 120. The outer shell 110 includes a mounting portion 112, a hollow handle 111 and a back cover 113. The mounting portion 112 is a frame that passes through both sides. The water outlet cover 140 and the back cover 113 are respectively provided on both sides of the mounting portion 112 and enclose a space that is connected to the interior of the handle 111. The water inlet pipe 120 is provided in the handle 111, and the second shell 200 is provided in the outer shell 110.

[0104] Among them, the shell 110 also includes a second partition plate 114. Specifically, the second partition plate 114 is arranged along the radial direction of the mounting portion 112, wherein the second partition plate 114 is arranged on the side of the second cover body 230 facing away from the air outlet 211, and an annular plate 115 extends from the side of the second partition plate 114 close to the second cover body 230, thereby enclosing a water cavity 160 between the second partition plate 114 and the second cover body 230.

[0105] refer to Figure 2 、 3 In some embodiments, the second partition plate 114 is disposed between the second housing 200 and the back cover 113. The second partition plate 114 and the back cover 113 further define a receiving chamber 116. A connecting hole 1141 is disposed on and passes through the second partition plate 114. The first cover 210 and the water outlet cover 140 define a water outlet chamber 150.

[0106] refer to Figure 11 、 12 In some specific embodiments of the present invention, the driving member 331 is an impeller, including a rotating shaft 3311 and a plurality of blades 3316, wherein the blades 3316 are fitted with a gap against the inner wall of the water chamber 160, and water can flow in the gap.

[0107] refer to Figure 2 、 3, 11-13, the energy storage assembly 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 shell 100, a second connecting portion 421 is provided on the inner peripheral wall of the sleeve 420, a third connecting portion 3314 is provided on the outer peripheral wall of the portion of the rotating shaft 3311 that penetrates the accommodating cavity 116, the sleeve 420 is sleeved on the rotating shaft 3311, and the second connecting portion 421 and the third connecting portion 3314 cooperate to ensure a driving connection between the sleeve 420 and the rotating shaft 3311.

[0108] According to an embodiment of the present invention, when water flows into the water chamber 160 and impacts the impeller to rotate (assuming a clockwise direction), 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 is driven by the sleeve 420 to twist and deform, and the kinetic energy of the water flow is converted into 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 increases accordingly. When the force exerted by the torsion spring 410 on the sleeve 420 equals the impact force of the water flow on the impeller, the impeller stops rotating and the torsion spring 410 ceases to deform. During this process, no gas enters the water outlet chamber 150. At this point, the water flows toward the water outlet through the gap between the blades 3316 and the inner wall of the water passage chamber 160. When the showerhead 1000 is finished using and the user turns off the water supply, the impeller is no longer impacted by the water flow. The torsion spring 410 then begins to restore its shape, driving the sleeve 420 and impeller to rotate (this time counterclockwise), thereby driving the bowl 311 to discharge gas toward the air outlet 211.

[0109] It is understood that one of the second connecting portion 421 and the third connecting portion 3314 can be a block, and the other can be a slot. Alternatively, both the second connecting portion 421 and the third connecting portion 3314 can be adhesive or welded parts, which is not limited here, as long as the driving connection between the sleeve 420 and the rotating shaft 3311 can be achieved.

[0110] refer to Figure 2 In some embodiments, a fourth connecting portion 1142 is provided on a side of the second partition plate 114 close to 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 can be a protrusion, and one end of the torsion spring 410 is fixedly connected to the protrusion.

[0111] refer to Figure 9 、 11, 12, 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 rotating shaft hole 3312. A transmission shaft 512 is provided on one end of the transmission member 510 close to the first shaft section 3321, and a third shaft hole 3322 is provided on one end of the first shaft section 3321 close to the transmission member 510. The transmission member 510 and the first shaft section 3321 are driven and connected via 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 rotating shaft hole 3312.

[0112] Among them, when the first limit member 511 and the second limit 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 and connected; when the first limit member 511 and the second limit 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.

[0113] It can be understood that the first limit member 511 and the second limit member 3315 can both be magnetic members, and the magnetism of the first limit member 511 and the second limit member 3315 are opposite. When the first limit member 511 and the second limit member 3315 are relative to each other, the two are attracted to each other through magnetic force, thereby realizing a drive connection. At this time, the transmission assembly 500 is in the second state. When the first limit member 511 and the second limit member 3315 are staggered from each other, the transmission assembly 500 is in the first state, and the transmission member 510 can rotate relative to the shaft hole 3312.

[0114] Alternatively, one of the first limit member 511 and the second limit member 3315 can be a limit block, and the other can be a limit slot. When the transmission assembly 500 is in the first state, the limit block and the limit slot are disengaged from each other, and when the transmission assembly 500 is in the second state, the limit block and the limit slot are engaged with each other.

[0115] Alternatively, a ballpoint pen rotating structure may be designed between the first limiting member 511 and the second limiting member 3315 to achieve a disengaged state or an engaged state.

[0116] It can be understood that the state of the transmission component 500 can be changed by motor drive. For example, when the transmission component 500 is required to be in the first state, the motor can drive the transmission component 500 to move and disengage the first limit member 511 and the second limit member 3315 from each other. Otherwise, the transmission component 500 is driven to connect the first limit member 511 and the second limit member 3315 to each other.

[0117] refer to Figure 11 、 12In some specific embodiments of the present invention, a water channel 3313 is provided at one end of the rotating shaft hole 3312 facing away from the energy storage assembly 400. Specifically, the water channel 3313 can be a groove hollowed out from the inner wall of the rotating shaft hole 3312, or a groove formed by utilizing the space between any two adjacent second limiting members 3315. The water channel 3313 connects the water chamber 160 and the rotating shaft hole 3312. When the transmission member 510 and the drive shaft 332 are inserted into the rotating shaft hole 3312, water flowing through the water chamber 160 can enter the rotating shaft hole 3312 through the water channel 3313, and utilize the pressure or buoyancy of the water 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 separate from each other. That is, when water enters the shower head 1000 , although the impeller can be driven to rotate and drive the energy storage assembly 400 to store energy, there is no transmission between the transmission member 510 and the rotating shaft hole 3312 . Therefore, the transmission member 510 does not rotate, and then the drive shaft 332 does not rotate either, and the air suction device 300 does not supply air to the air outlet 211 .

[0118] After the shower head 1000 is used, no water flows into the shower head 1000 and no water flows into the shaft hole 3312. The transmission member 510 is reset and the first limit member 511 and the second limit member 3315 are connected to each other. At this time, when the torsion spring 410 drives the shaft 3311 to rotate, the drive shaft 332 is also rotated through the transmission member 510, and the bowl portion 311 is used to output gas to the water outlet chamber 150 to discharge residual water.

[0119] It is understandable that the resetting of the transmission member 510 can be achieved in a variety of ways. When the water pressure or buoyancy is lost, the transmission member 510 can be reset by its own weight, or the user can swing the shower head 1000 to reset the transmission member 510 under inertia.

[0120] refer to Figure 12 In some specific embodiments of the present invention, the transmission assembly 500 further includes an elastic member 520, which may be a spring or other elastically deformable structural member. One end of the elastic member 520 abuts against the end of the transmission member 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, or after the showerhead 1000 is used and the water supply is turned off), the elastic member 520 provides elastic force to the transmission member 510, thereby connecting the first stopper 511 and the second stopper 3315.

[0121] According to the embodiment of the present application, the interconnected state of the first limiter 511 and the second limiter 3315 in the initial state, and the reset process of the transmission member 510 after the shower head 1000 is used can be achieved by the elastic member 520.

[0122] refer to Figure 12 、 13 In some specific embodiments of the present invention, a pressure relief hole 422 is further provided on the bottom wall of the sleeve 420. Specifically, the pressure relief hole 422 passes through the bottom wall of the sleeve 420 and connects the interior of the sleeve 420 with the accommodating chamber 116. Therefore, when the transmission member 510 moves, the air pressure in the sleeve 420 can be balanced, and there will be no pressure buildup that affects the movement of the transmission member 510.
