Description

Technical Field

[0001] This utility model relates to the field of shower equipment, 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

The adjusting member is slidably disposed at one end of the pressure stabilizing channel near the air storage chamber. The sealing member is disposed at one end of the pressure stabilizing channel away from the air storage chamber. The first elastic member abuts against the adjusting member and the sealing member. The adjusting member is sealed to the inner peripheral wall of the pressure stabilizing channel. When the pressure exerted by the gas in the air storage chamber on the adjusting member is greater than the elastic force of the first elastic member, the adjusting member compresses the first elastic member and moves in a direction closer to the sealing member to reduce the air pressure in the air storage chamber.

[0025] According to some embodiments of the present invention, the first housing is further provided with a pressure stabilizing channel, and the pressure stabilizing channel is connected to the gas storage cavity through a first pressure stabilizing hole; The shower head also includes a pressure stabilizing component disposed in the pressure stabilizing channel.

Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown 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 this utility model, and should not be construed as limiting this utility model.

[0031] refer to Figure 1 In some specific embodiments of this utility model, a shower head 1000 is provided, which can utilize gas from an external air source to drive out residual water that cannot be discharged after the water flow stops, thus avoiding dripping, bacterial growth in residual water, and other phenomena. It should be specifically noted here that the "external air source" referred to here and in the following content can be the external atmosphere or a gas supply device such as a gas cylinder other than the shower head 1000.

[0032] refer to Figure 1-5 The 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 143, and a water outlet channel 1421 arranged sequentially. Water can flow from the water inlet channel 121 into the water outlet chamber 143 and out through the water outlet channel 1421 for use. The first housing 100 also includes 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 143 through the air outlet 211 to increase the air pressure in the water outlet chamber 143, thereby squeezing out the residual water in the water outlet chamber 143 from the water outlet channel 1421, thus avoiding dripping, bacterial growth, and other phenomena.

[0033] 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.

[0034] A piston diaphragm assembly 310 is disposed in the suction chamber 240. The piston diaphragm assembly 310 includes at least one bowl portion 311, the opening of which faces the air outlet 211. The bowl portion 311 and the inner wall of the suction chamber 240 form a pump chamber 320. The air inlet end of the air 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 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 leave the pump chamber 320 unidirectionally from the air outlet 211 and enter the water outlet chamber 143. 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.

[0035] Understandably, when water flows into the shower head 1000 during normal use, there is no need for the air in the pump chamber 320 to enter the outlet chamber 143, so as not to affect 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, is it necessary for air to enter the outlet chamber 143 to remove the residual water.

[0036] In some specific embodiments (not shown), the air outlet 211 can be directly connected to the water outlet chamber 143. In this case, when water flows into the shower head 1000, the drive assembly 330 is not controlled to drive the bowl 311 to move and / or deform, so no gas enters the water outlet chamber 143. When no water flows into the shower head 1000 after use, the drive assembly 330 is then controlled to drive the bowl 311 to move and / or deform, thereby allowing gas to enter the water outlet chamber 143. Specifically, an electronically or manually controlled device can be set up, whereby the drive assembly 330 is controlled by the user's control signal or the water inlet signal of the shower head 1000, so that the bowl 311 is only driven to move and / or deform when no water flows into the shower head 1000.

[0037] refer to Figure 4-6In some specific embodiments, the air outlet 211 may not be directly connected to the water outlet chamber 143. Specifically, an air storage chamber 131 is provided between the air outlet 211 and the water outlet chamber 143. Gas can enter the air storage chamber 131 from the air outlet 211 and then enter the water outlet chamber 143 from the air storage chamber 131. A switch assembly 170 is also provided between the air storage chamber 131 and the water outlet chamber 143. When the switch assembly 170 is in the closed state, regardless of whether water flows into the shower head 1000, the drive assembly 330 can be controlled to drive the bowl 311 to move and / or deform. After the gas enters the air storage chamber 131, it is stored in the air storage chamber 131. When the shower head 1000 is finished and no more water flows in, the user can control the switch assembly 170 to switch to the open state. Therefore, the gas in the air storage chamber 131 can enter the water outlet chamber 143 to squeeze out the residual water. Furthermore, the shower head 1000 may also include an exposed button 173, through which the user can change the state of the switch assembly 170 to control the gas in the air storage chamber 131 to enter the water outlet chamber 143.

[0038] According to the specific embodiments provided by this utility model, after the shower head 1000 is used (when no water flow enters), gas can be sent into the water outlet chamber 143 to increase the air pressure in the water outlet chamber 143, thereby discharging the residual water in the water outlet chamber 143 and avoiding problems such as dripping water or bacterial growth in residual water after the shower head 1000 is turned off.

[0039] Understandably, the drive assembly 330 can be a drive device with a motor. When the air outlet 211 can be directly connected to the water outlet chamber 143, the drive assembly 330 can be controlled by the user via a button, infrared signal, etc., so that the drive assembly 330 moves and drives the bowl 311 to move and / or deform only after the shower head 1000 has been used. When an air storage chamber 131 is provided between the air outlet 211 and the water outlet chamber 143, the user can control the drive assembly 330 to work at any time, so that the gas is stored in the air storage chamber 131. After the shower head 1000 has been used, the switch assembly 170 is turned on to drain the water.

[0040] 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.

[0041] 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.

[0042] refer to Figure 2-5In some specific embodiments of this utility model, the first housing 100 further includes a second housing 200, which forms an air intake chamber 240. Specifically, the second housing 200 can be a part of the first housing 100, integrally formed with the first housing 100, or it can be an independent housing structure assembled in the first housing 100. An air outlet 211 is provided on one wall surface of the second housing 200.

[0043] refer to Figure 5 , 7 In some specific embodiments of this utility model, the second housing 200 includes a cylindrical portion 220, with a partition plate 221 arranged radially on the cylindrical portion 220. A cylinder 222 is arranged on the partition plate 221. Specifically, the cylinder 222 extends outward from the direction opposite to the vent 211. The cylinder 222 has a hollow design and is connected to 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 is directly connected to the space inside the cylinder 222. Alternatively, the end of the cylinder 222 near the vent 211 can still be blocked by the partition plate 221. An opening penetrating the partition plate 221 is provided on the partition plate 221 enclosed in the cylinder 222, and the opening is provided corresponding to the vent 211, thereby allowing the vent 211 to be connected to the space inside the cylinder 222.

[0044] 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.

[0045] 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, and the air outlet 211 is connected to the pump cavity 320.

[0046] Therefore, when the bowl 311 is driven to slide back and forth in the cylinder 222, the volume of the pump chamber 320 changes, causing the gas in the pump chamber 320 to leave through the vent 211. It is understood that if the bowl 311 is made of a deformable material such as rubber, when the bowl 311 moves to abut against the partition plate 221, it can continue to deform towards the vent 211, and the gas in the bowl 311 will also be input into the vent 211.

[0047] refer to Figure 3 , 7 In some specific embodiments of this utility model, the first housing 100 is also provided with an air intake channel 250, which connects the air intake chamber 240 and the external air source.

[0048] 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.

[0049] In some specific embodiments of this utility model, 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.

[0050] 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.

[0051] 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.

[0052] In some specific embodiments of this utility model, 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.

[0053] 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.

[0054] Understandably, the second one-way component can be a check valve, a shut-off valve, or a foldable diaphragm, and the diaphragm can only be folded back and forth in the direction of gas supply to open and close the gas supply channel.

[0055] refer to Figure 2 , 3 In some specific embodiments of this utility model, 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.

[0056] refer to Figure 3 , 7 -8. In some specific embodiments of this utility model, 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 part 220. The cylindrical part 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 part 220 extends a partition plate 221 along its own radial direction, and the air supply hole 2211 is provided on the partition plate 221 and penetrates the partition plate 221.

[0057] 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 of the air storage chamber 131 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.

[0058] refer to Figure 5 , 9 In some specific embodiments of this utility model, 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 is sandwiched between the first cover body 210 and the cylindrical portion 220. At this time, the bowl portion 311 is equivalent to being fastened onto the first cover body 210, and together with the first cover body 210, they form 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.

[0059] According to the embodiment of this utility model, at this time, 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 gas storage chamber 131, 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.

[0060] refer to Figure 5 , 7 In some specific embodiments of this utility model, the partition plate 221 also 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 prevents 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.

[0061] 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.

[0062] 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.

[0063] refer to Figure 9In some specific embodiments of this utility model, 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 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 arranged in a one-to-one correspondence with the N cylinders 222.

[0064] Understandably, the first cover 210 also has N air outlets 211 and air replenishment grooves 212, and the 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.

[0065] refer to Figure 9 , 10 In some specific embodiments of this utility model, the membrane portion 312 is provided with a vent 313 corresponding to the air supply hole 2211, thereby preventing the membrane portion 312 from blocking the gas flow between the air supply hole 2211 and the air supply groove 212. The vent 313 can be set with a large aperture, thereby encompassing all N air supply holes 2211. Alternatively, the vent 313 can be set as N holes with smaller apertures, corresponding one-to-one with each air supply hole 2211.

[0066] In some specific embodiments of this utility model, the second one-way component is disposed in the vent 313.

[0067] 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 can restrict gas from entering the pump chamber 320 from the gas supply channel in one direction.

[0068] refer to Figure 9 , 10In some specific embodiments of this utility model, the second one-way component includes a diaphragm 314 and a second 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 second 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 second connecting portion 315 is disposed at any point on the outer edge of the diaphragm 314. When the other end of the second connecting portion 315 is connected to the vent 313 or the air replenishment hole 2211, the diaphragm 314 can be folded with the second connecting portion 315 as the axis.

[0069] 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 by 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.

[0070] 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.

[0071] refer to Figure 3 , 4 In some specific embodiments of this utility model, 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.

[0072] 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.

[0073] 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.

[0074] 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 the impeller, and the kinetic energy of the water flow is used to make the drive disc 333 reciprocate along the axial direction of the drive shaft 332.

[0075] refer to Figure 9 , 11 In some specific embodiments of this utility model, 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. Among them, with the connection between the drive disk 333 and the drive shaft 332 as the center, the first hinge members 3331 are arranged in a circular array on the outer edge of the drive disk 333.

[0076] 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.

[0077] refer to Figure 3-5 11. In some specific embodiments of this utility model, the drive disk 333 is bowl-shaped and its opening faces away from the piston diaphragm assembly 310.

[0078] In a specific embodiment of this utility model, 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.

[0079] refer to Figure 3-5 11-12, In some specific embodiments of this utility model, 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 3322, wherein the included angle β between the first shaft segment 3321 and the second shaft segment 3322 is an obtuse angle, and the first shaft segment 3321 partially passes through the first shaft hole 231. The second shaft segment 3322 is located in the air intake chamber 240. The portion of the first shaft segment 3321 facing away from the second shaft segment 3322 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 3322. Specifically, the drive disk 333 is roughly disc-shaped, and a third shaft hole 3332 is provided in the middle of the drive disk 333. The second shaft segment 3322 passes through the third shaft hole 3332 to complete the pivot connection.

[0080] Specifically, the drive component 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.

[0081] In this 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 3322, 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 3322 rotates around the axis of the first shaft segment 3321. The rotation trajectory of the second shaft segment 3322 is roughly conical. Since the second shaft segment 3322 and the third 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.

[0082] It should be noted that even if there is friction between the second shaft segment 3322 and the third shaft hole 3332, since the drive disk 333 and the bowl 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.

[0083] refer to Figure 2-513. In some specific embodiments of this utility model, the first housing 100 further includes a water passage cavity 160. Specifically, the first housing 100 includes a water outlet cover 140, which includes a water outlet cover 142 and a water sealing plate 141. A water outlet channel 1421 is disposed on the water outlet cover 142. Specifically, the water outlet channel 1421 can be a water outlet hole, a water outlet nozzle, etc. The water sealing plate 141 is disposed between the water outlet cover 142 and the second housing 200. The side of the water sealing plate 141 near the water outlet cover 142 forms a water outlet cavity 143 with the water outlet cover 142. The water outlet channel 1421 connects the water outlet cavity 143 to the outside. An annular plate 1411 is disposed on the side of the water sealing plate 141 near the second housing 200. The water sealing plate 141 and the second housing 200 form a water passage cavity 160 that communicates with the water inlet channel 121 through the annular plate 1411. 0. The portion of the water sealing plate 141 surrounding the annular plate 1411 is provided with a water passage hole 1413 connecting the water passage cavity 160 and the water outlet cavity 143. It can be understood that, in this embodiment of the utility model, "the water inlet channel 121 is connected to the water outlet cavity 143" means that the water inlet channel 121 is connected to the water passage cavity 160, and the water passage cavity 160 is connected to the water outlet cavity 143. The water flow in the water inlet channel 121 can pass through the water passage cavity 160 and then enter the water outlet cavity 143.

[0084] The drive component 331 is rotatably disposed in the water passage cavity 160. The annular plate 1411 is provided with a plurality of inclined water holes 1412. The inclined water holes 1412 connect the water inlet channel 121 and the water passage cavity 160. Thus, the water flow from the water inlet channel 121 can enter the water passage cavity 160 through the inclined water holes 1412 and impact the drive component 331. The drive shaft 332 causes the drive disc 333 to move, thereby controlling the movement and / or deformation of the bowl 311. After impacting the drive component 331, the water flow enters the water outlet cavity 143 through the water passage holes 1413.

[0085] 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, where water flow impacts the hydroelectric generator to generate electrical energy, which in turn operates the motor and causes the drive shaft 332 to rotate.

[0086] In this embodiment of the utility model, the drive component 330 can use the water flow energy from the shower head 1000 to complete the process of inflation and replenishment without additional energy consumption. The user can complete the air storage process simultaneously during the shower without any additional operation.

[0087] refer to Figure 2 , 414. In some specific embodiments of this utility model, the first housing 100 further includes a gas storage chamber 131. A connecting hole 1341 is provided between the gas storage chamber 131 and the water outlet chamber 143, that is, the gas storage chamber 131 and the water outlet chamber 143 are connected through the connecting hole 1341, and the gas in the gas storage chamber 131 can enter the water outlet chamber 143 through the connecting hole 1341. In addition, an air inlet 133 is also provided between the gas storage chamber 131 and the air outlet 211, and the gas in the pump chamber 320 can enter the gas storage chamber 131 after passing through the air outlet 211 and the air inlet 133 in sequence.

[0088] The shower head 1000 also includes a switch assembly 170, which is disposed in the connection hole 1341 to control the opening and closing of the connection hole 1341, thereby controlling whether the air storage chamber 131 and the water outlet chamber 143 are connected. Specifically, the switch assembly 170 has a first state of blocking the connection hole 1341 and a second state of opening the connection hole 1341.

[0089] According to the specific embodiment provided by this utility model, the air intake device 300 can input gas into the air storage chamber 131 for storage. After the shower head 1000 is used, the user can turn on the switch assembly 170 to allow the gas in the air storage chamber 131 to enter the water outlet chamber 143. The pressure of the gas is used to discharge the residual water in the water outlet chamber 143, thus avoiding problems such as dripping water or bacterial growth in residual water after the shower head 1000 is turned off.

[0090] refer to Figure 2-4 In some specific embodiments of this utility model, the first housing 100 further includes an outer shell 110, a water inlet pipe 120, and an air storage component 130. The air storage component 130 has an air storage chamber 131, and an air inlet hole 133 communicating with the air storage chamber 131 is provided on the side of the air storage component 130 near the water outlet cover 140. The water inlet pipe 120 has a water inlet channel 121. The outer casing 110 includes an interconnected mounting portion 112 and a hollow handle 111. The mounting portion 112 is a frame extending through both sides, forming a space communicating with the interior of the handle 111. An air storage component 130 and a water outlet cover 140 are disposed in the mounting portion 112 and located on opposite sides of the through portion 112. The air storage component 130 and the water outlet cover 140 form an air inlet chamber 150. A second casing 200 can be disposed in the air inlet chamber 150. An air inlet channel 250 connects the air inlet chamber 150 and the air intake chamber 240. A water inlet pipe 120 passes through the handle 111 to communicate with the water outlet chamber 143.

[0091] In some embodiments, the first housing 100 is provided with a channel for connecting the air inlet chamber 150 and the external air source. For example, a channel is provided on the housing 110, the air storage component 130, and the water outlet cover 140 to connect the air inlet chamber 150 and the external air source, or the gap between the air storage component 130 and the water outlet cover 140 during assembly is used to connect the air inlet chamber 150 and the external air source, thereby ensuring that the air intake device 300 provided in the air inlet chamber 150 has sufficient air source to deliver to the air storage chamber 131.

[0092] refer to Figure 14 In some embodiments, the air storage component 130 is provided with an installation groove 132 on the side near the water outlet cover 140. This groove can be a recess or a groove-shaped space formed by extending arc-shaped ribs. The air inlet 133 is provided on the bottom wall of the installation groove 132. The air intake device 300 is installed in the installation groove 132 so that the air outlet 211 and the air inlet 133 are aligned, thereby achieving accurate positioning and preventing the air intake device 300 from shaking in the air intake chamber 150.

[0093] refer to Figure 6 , 14 In some specific embodiments of this utility model, a first connecting part 134 is provided between the gas storage component 130 and the water outlet cover 140. The first connecting part 134 is axially penetrating to form a connecting hole 1341 connecting the gas storage chamber 131 and the water outlet chamber 143. The peripheral wall of the first connecting part 134 is penetrating to form an installation channel 1342. The switch assembly 170 is inserted into the connecting hole 1341 radially along the connecting hole 1341 through the installation channel 1342. The switch assembly 170 has a first state and a second state in the connecting hole 1341. When it is in the first state, the switch assembly 170 blocks the connecting hole 1341. At this time, the gas storage chamber 131 and the water outlet chamber 143 are not connected. When it is in the second state, the switch assembly 170 opens the connecting hole 1341, so that the gas storage chamber 131 and the water outlet chamber 143 are connected.

[0094] It is understood that the switch assembly 170 can be manually controlled by the user or driven by a motor, and there is no limitation here. When the user does not operate the switch assembly 170, the switch assembly 170 is in the first state.

[0095] Therefore, when the suction device 300 is activated, gas can enter the air storage chamber 131. Since the switch assembly 170 blocks the connection hole 1341, the gas can be stored in the air storage chamber 131, and the air pressure in the air storage chamber 131 is higher than atmospheric pressure. After the user finishes using the water outlet function of the shower head 1000, due to the shape of the cover and the small size of the water outlet hole, water is easy to remain in the water outlet chamber 143 and cannot be completely drained. At this time, the user can control the switch assembly 170 to switch to the second state, and the connection hole 1341 connects the air storage chamber 131 and the water outlet chamber 143, so that the gas in the air storage chamber 131 rushes into the water outlet chamber 143. The pressure of the gas is used to drain the residual water in the water outlet chamber 143, avoiding problems such as dripping water or bacterial growth in residual water after the shower head 1000 is turned off.

[0096] refer to Figure 5 , 15 -16. In some specific embodiments of this utility model, the gas storage component 130 is further provided with a pressure stabilizing channel 135. Specifically, the pressure stabilizing channel 135 can be a channel extending from the inner wall of the gas storage component 130 into the gas storage cavity 131, or it can be a channel extending from the outer wall of the gas storage component 130 away from the gas storage component 130. When the wall thickness of the gas storage component 130 is large, the pressure stabilizing channel 135 can also be formed on the inner side of the peripheral wall of the hollowed-out gas storage component 130. The pressure stabilizing channel 135 is connected to the gas storage cavity 131 through a first pressure stabilizing hole 1351.

[0097] The shower head 1000 also includes a pressure stabilizing component 136 disposed in a pressure stabilizing channel 135. The pressure stabilizing component 136 includes an adjusting member 1361, a first elastic member 1362, and a sealing member 1363. The first elastic member 1362 may be a spring. The adjusting member 1361 is slidably disposed at one end of the pressure stabilizing channel 135 near the air storage chamber 131. The sealing member 1363 is disposed at one end of the pressure stabilizing channel 135 away from the air storage chamber 131. The first elastic member 1362 abuts against the adjusting member 1361 and the sealing member 1363. When the pressure exerted by the gas in the air storage chamber 131 on the adjusting member 1361 is greater than the elastic force of the first elastic member 1362, the adjusting member 1361 is driven to compress the first elastic member 1362 and move toward the sealing member 1363 to reduce the air pressure in the air storage chamber 131.

[0098] It is understood that the sealing component 1363 can be an independent component, which is set in the pressure stabilizing channel 135 in the embodiment of this utility model. The sealing component 1363 can also be part of the wall of the gas storage component 130 and integrally formed with the gas storage component 130.

[0099] In some embodiments, the adjusting member 1361 may be configured as a piston or ball, etc., and the outer peripheral wall of the adjusting member 1361 is in sealed contact with the inner peripheral wall of the pressure regulating channel 135 and can slide relative to each other.

[0100] Therefore, when the pressure exerted by the gas in the gas storage chamber 131 on the regulating member 1361 is greater than the elastic force of the first elastic member 1362, the regulating member 1361 moves away from the gas storage chamber 131 against the spring force. At this time, some gas can enter the pressure stabilizing channel 135 through the first pressure stabilizing hole 1351, which is equivalent to increasing the volume of the gas storage chamber 131, thereby reducing the gas pressure in the gas storage chamber 131.

[0101] refer to Figure 15-16 In some embodiments, the adjusting member 1361 can be configured as a piston or a ball, and the sealing member 1363 is further provided with a second pressure-stabilizing hole 1364 connecting the pressure-stabilizing channel 135 and the outside. The first elastic member 1362 abuts against the adjusting member 1361 and the sealing member 1363 so that the adjusting member 1361 blocks the first pressure-stabilizing hole 1351 in the initial state. Along the axial direction of the pressure-stabilizing channel 135, the projected area of ​​the first pressure-stabilizing hole 1351 is defined as S1, the projected area of ​​the sealing member 1363 is defined as S2, and the projected area of ​​the pressure-stabilizing channel 135 is defined as S3, where S3 > S2 > S1. Thus, when the pressure exerted by the gas in the gas storage chamber 131 on the adjusting member 1361 is less than the elastic force of the first elastic member 1362, the adjusting member 1361 remains blocked by the elastic force of the first elastic member 1362, and the gas storage chamber 131 can continue to store gas and increase pressure. When the pressure exerted by the gas in the gas storage chamber 131 on the regulating member 1361 is greater than the elastic force of the first elastic member 1362, the regulating member 1361 moves against the elastic force. At this time, the first pressure stabilizing hole 1351 connects the gas storage chamber 131 and the pressure stabilizing channel 135. Since S3 > S2 > S1, an air passage gap is formed between the regulating member 1361 and the inner peripheral wall of the pressure stabilizing channel 135. The pressure stabilizing channel 135 is connected to the outside through the second pressure stabilizing hole 1364. Therefore, at this time, the high-pressure gas can flow to the outside through the pressure stabilizing channel 135 to achieve pressure relief, thereby reducing and stabilizing the gas pressure in the gas storage chamber 131 and preventing the shower head 1000 from bursting.

[0102] It should be noted that in this embodiment, "external environment" refers to the space outside the shower head 1000 (such as the bathroom environment) or the air inlet chamber 150 (in which case the pressure stabilizing channel 135 is located on the side wall of the air storage component 130 near the water outlet cover 140). The depressurized gas in the air storage chamber 131 can enter the bathroom environment or enter the air inlet chamber 150.

[0103] Since the material of the shower head 1000 housing can only withstand limited pressure, it is prone to bursting if the internal pressure is too high. According to the embodiment of this utility model, the shower head 1000 is provided with a pressure stabilizing component 136. By selecting springs of different models and specifications, different preset pressures are determined. When the pressure exerted by the gas in the air storage chamber 131 on the adjusting component 1361 is higher than the preset pressure of the spring, the adjusting component 1361 can overcome the spring force and move, thereby releasing some gas or increasing the volume of the air storage chamber 131, thereby reducing and stabilizing the air pressure in the air storage chamber 131 and preventing the shower head 1000 from bursting due to high pressure.

[0104] refer to Figure 15-16 In some embodiments of the utility model, the blocking member 1363 can move in the pressure stabilizing channel 135. The blocking member 1363 is provided with a first positioning part, and the pressure stabilizing channel 135 is provided with a second positioning part. The blocking member 1363 and the pressure stabilizing channel 135 can cooperate through the first positioning part and the second positioning part, so that the blocking member 1363 can be positioned at least two different positions in the axial direction of the pressure stabilizing channel 135.

[0105] Specifically, the first positioning part can be an external thread on the outer peripheral wall of the sealing member 1363, and the second positioning part can be an internal thread on the inner peripheral wall of the pressure stabilizing channel 135. Through the cooperation of the internal and external threads, the sealing member 1363 can be rotatably positioned in the pressure stabilizing channel 135, and the positioning position of the sealing member 1363 can be changed as the number of rotations varies.

[0106] Alternatively, one of the first positioning part and the second positioning part can be multiple positioning recesses arranged axially along the pressure stabilizing channel 135, and the other can be a telescopic component, such as a telescopic component composed of a spring and a pin. The first positioning part and the second positioning part are respectively disposed on the outer peripheral wall of the sealing member 1363 and the inner peripheral wall of the pressure stabilizing channel 135. The sealing member 1363 is movable in the pressure stabilizing channel 135. When it moves to the point where the first positioning part and the second positioning part are opposite each other, the telescopic component extends into the positioning recess and locks in place, thereby achieving positioning. As the telescopic component locks into different positioning recesses, the sealing member 1363 can be positioned in different positions.

[0107] According to this embodiment of the utility model, the user can adjust the position of the sealing member 1363 to vary the spring force applied to the adjusting member 1361 in the initial state, i.e., the preload force. This results in different preset air pressures for the adjusting member 1361 to release pressure, thereby regulating the air pressure within the air storage chamber 131 to meet different user needs. For example, when the user only needs to drain residual water, the sealing member 1363 can be adjusted to a smaller spring preload force. At this time, the air pressure within the air storage chamber 131 is lower, sufficient for drainage. When the user finds a lot of impurities and dirt on the water outlet channel 1421, the spring preload force can be adjusted to a larger value. At this time, the air pressure within the air storage chamber 131 is higher. After opening the switch assembly 170, high-pressure gas is used to flush the water outlet channel 1421 to remove impurities and dirt.

[0108] refer to Figure 2 , 4 -6. In some specific embodiments of this utility model, the switch assembly 170 includes a second elastic member 172 and a piston assembly 171. The second elastic member 172 abuts against the first housing 100 and the piston assembly 171. The piston assembly 171 is provided with a connecting portion 1711. When the user does not apply force to the switch assembly 170, the piston assembly 171 moves to a position where the connecting portion 1711 is misaligned with the connecting hole 1341 under the elastic force of the second elastic member 172. At this time, the switch assembly 170 is in the first state of blocking the connecting hole 1341. When the user applies force to the switch assembly 170, the piston assembly 171 overcomes the elastic force of the second elastic member 172, compresses the second elastic member 172, and moves to a position where the connecting portion 1711 communicates with the connecting hole 1341. At this time, the switch assembly 170 is in the second state of opening the connecting hole 1341.

[0109] In some specific embodiments of this utility model, in order to facilitate the user to apply force and operate the switch assembly 170, the housing 110 is provided with a button hole 1111 that penetrates the housing wall. The shower head 1000 also includes a button 173, which is movably disposed in the button hole 1111 and drivenly connected to the piston assembly 171. When the user presses the button 173, the piston assembly 171 can be moved and the connection hole 1341 can be opened.

[0110] In some specific embodiments of this utility model, the button hole 1111 is provided on the handle 111, and the switch assembly 170 also includes a swing member 174 provided in the handle 111. The swing member 174 can be configured as a fan shape or the like. A second rotating shaft 122 is provided on one of the outer wall of the water inlet pipe 120 and the swing member 174, and a second shaft hole 175 is provided on the other. The swing member 174 is oscillating in the handle 111 through the cooperation of the second rotating shaft 122 and the second shaft hole 175. Along the swing direction of the swing member 174, one end of the swing member 174 abuts against the piston assembly 171, and the other end abuts against the button 173. Thus, when the user presses the button 173, the swing member 174 can be used to convert the force perpendicular to the movement direction of the piston assembly 171 into a force parallel to the movement direction of the piston assembly 171, making the operation smoother and less strenuous, and without jamming.

[0111] refer to Figure 6 In some specific embodiments of this utility model, the connecting part 1711 can be a through hole (not shown) that is radially through the piston assembly 171, or it can be a section of the piston assembly 171 with a diameter smaller than the diameter of the connecting hole 1341. As long as the gas can enter the water outlet chamber 143 through the connecting hole 1341, no specific limitation is made here.
