Description

[0001] This application is a divisional application of the application filed on September 5, 2025, with application number 202511261266.6 and invention title "Shower Head". Technical Field

[0002] This invention relates to the field of shower heads, and in particular to a shower head. Background Technology

[0003] 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

[0004] This invention proposes a shower head that aims to solve the technical problem of difficulty in draining residual water from shower heads in the prior art, making it difficult to completely drain the water.

[0005] To achieve the above objectives, a first aspect of the present invention provides a shower head, comprising: The first housing includes a water inlet channel, a water outlet chamber, and a water outlet channel. Water can flow into the water outlet chamber from the water inlet channel and out through the water outlet channel. The first housing also includes a gas storage chamber. A connection hole is provided between the gas storage chamber and the water outlet chamber. Gas in the gas storage chamber can enter the water outlet chamber through the connection hole. An air intake device is disposed in the first housing and connected to the air storage chamber, for inputting gas into the air storage chamber; A switch assembly is disposed in the connection hole, the switch assembly having a first state of blocking the connection hole and a second state of opening the connection hole.

[0006] According to the first aspect of the present invention, after using the shower head, the user can control the switch assembly to switch to the second state, and the connection hole connects the air storage chamber and the water outlet chamber, so that the gas in the air storage chamber rushes into the water outlet chamber, and the pressure of the gas is used to discharge the residual water in the water outlet chamber, so as to avoid problems such as dripping water or bacteria growing in residual water after the shower head is turned off.

[0007] 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.

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.

Detailed Implementation

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] refer to Figure 1 In some specific embodiments of the present invention, a shower head is provided that can store gas from an external air source inside the shower head, and use the stored air to drive out residual water left in the shower head 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 thereafter can be the external atmosphere or a gas supply device such as a gas cylinder other than the shower head.

[0033] refer to Figure 1-8 The shower head provided in this embodiment includes a first housing 100, an air intake device 300, and a switch assembly 170. The first housing 100 includes a water inlet channel 121, a water outlet chamber 143, and a water outlet channel 1421 connected in sequence. Water can flow from the water inlet channel 121 into the water outlet chamber 143 and be output from the water outlet channel 1421 for use. The first housing 100 is also provided with an air storage chamber 131. The air storage chamber 131 and the water outlet chamber 143 are connected by a connecting hole 1341. Gas in the air storage chamber 131 can enter the water outlet chamber 143 through the connecting hole 1341.

[0034] The suction device 300 is disposed in the first housing 100 and connected to the air storage chamber 131, thereby the suction device 300 can draw gas from the space outside the air storage chamber 131 and input it into the air storage chamber 131.

[0035] The switch assembly 170 is disposed in the connection hole 1341 to control the opening and closing of the connection hole 1341, thereby controlling whether the gas storage chamber 131 and the water outlet chamber 143 are connected.

[0036] According to the specific embodiments provided by the present invention, the air intake device 300 can input gas into the air storage chamber 131 for storage, and when the shower head is used, the switch assembly 170 can be turned on to allow the gas in the air storage chamber 131 to enter the water outlet chamber 143, and the residual water in the water outlet chamber 143 can be discharged by the pressure of the gas, so as to avoid problems such as dripping water or bacteria growing in residual water after the shower head is turned off.

[0037] refer to Figure 2-8 In some specific embodiments of the present invention, the first housing 100 includes an outer shell 110, a water inlet pipe 120, an air storage component 130, and a water outlet cover 140. The water outlet cover 140 is provided with a water outlet cavity 143 and a water outlet channel 1421 connecting the water outlet cavity 143 to the outside. Specifically, the water outlet channel 1421 can be a water outlet hole, a water outlet nozzle, etc. The air storage component 130 is provided with an air storage cavity 131, and an air inlet hole 133 connecting the air storage cavity 131 is provided on the side of the air storage component 130 near the water outlet cover 140. The air outlet end of the air intake device 300 is directly opposite the air inlet hole 133. The water inlet pipe 120 is provided with an 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, and the air intake device 300 may be disposed in the air inlet chamber 150. The air storage chamber 131 and the water outlet chamber 143 are connected by a connecting hole 1341, allowing gas in the air storage chamber 131 to enter the water outlet chamber 143 through the connecting hole 1341. A water inlet pipe 120 passes through the handle 111 to communicate with the water inlet channel 121 and the water outlet chamber 143.

[0038] 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.

[0039] refer to Figure 4In 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 to achieve accurate positioning and prevent the air intake device 300 from shaking in the air intake chamber 150.

[0040] It is understood that the air intake device 300 can be an electric or manual air pump or a device that is driven by the water flow passing through the shower head to supply air to the air storage chamber 131. As long as air can be input into the air storage chamber 131, no specific limitation is made here.

[0041] refer to Figure 4-5 In some specific embodiments of the present invention, a first connecting portion 134 is provided between the gas storage component 130 and the water outlet cover 140. The first connecting portion 134 extends axially to form a connecting hole 1341 that connects the gas storage chamber 131 and the water outlet chamber 143. The peripheral wall of the first connecting portion 134 extends to form an installation channel 1342. The switch assembly 170 passes through the installation channel 1342 and radially enters the connecting hole 1341. 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, and 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.

[0042] 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.

[0043] Therefore, when the air intake 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. When the user finishes using the shower head's water function, due to the shape of the cover and the small size of the water outlet, water is easily left 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 is turned off.

[0044] Understandably, the activation time of the air intake device 300 varies depending on its type. For example, when the air intake device 300 is an electric or manual air pump, the user can activate it before or during showering. When the air intake device 300 is driven by the shower water flow, it automatically starts supplying air when the user begins using the shower.

[0045] refer to Figure 8-9 In some specific embodiments of the present invention, a pressure stabilizing channel 135 is also provided on the gas storage component 130. 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 perforated gas storage component 130. The pressure stabilizing channel 135 is connected to the gas storage cavity 131 through a first pressure stabilizing hole 1351.

[0046] The shower head also includes a pressure stabilizing component 136 disposed in the 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 the other 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.

[0047] It is understood that the sealing component 1363 can be an independent component, which is disposed in the pressure stabilizing channel 135 in the embodiments of the present invention. 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.

[0048] 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.

[0049] 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.

[0050] refer to Figure 9 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 from bursting.

[0051] It should be noted that in this embodiment, "external environment" is relative to the air storage chamber 131 and the pressure stabilizing channel 135. "External environment" can refer to the space outside the shower head (such as the bathroom environment) or the air inlet chamber 150 (at this time, the pressure stabilizing channel 135 is set 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.

[0052] Since the material of the shower head housing can only withstand a limited amount of pressure, it is prone to bursting if the internal pressure is too high. According to the embodiment of the present invention, the shower head 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 from bursting due to high pressure.

[0053] refer to Figure 8 and Figure 9In some embodiments of the invention, 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.

[0054] 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.

[0055] 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.

[0056] According to an embodiment of the present invention, 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 gas 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 lower spring preload force. At this time, the gas pressure within the air storage chamber 131 is lower, sufficient for drainage. When the user finds a large amount of impurities and dirt on the water outlet channel 1421, the spring preload force can be adjusted to a higher value. At this time, the gas pressure within the air storage chamber 131 is higher, and after opening the switch assembly 170, high-pressure gas is used to flush the water outlet channel 1421 to remove impurities and dirt.

[0057] refer to Figure 2 , Figure 5-7In some specific embodiments of the present invention, 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 a 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 a second state of opening the connecting hole 1341.

[0058] In some specific embodiments of the present invention, 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.

[0059] In some specific embodiments of the present invention, 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.

[0060] refer to Figure 7 In some specific embodiments of the present invention, the connecting part 1711 may be a through hole (not shown) that is radially through the piston assembly 171, or it may be a section of the piston assembly 171 with a diameter smaller than that 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.

[0061] refer to Figure 3-6In some specific embodiments of the present invention, the first housing 100 is further provided with an air intake chamber 240, a first air intake channel and a second air intake channel 250. The air storage chamber 131 and the air intake chamber 240 are connected through the first air intake channel, and the second air intake channel 250 is used to allow gas from an external air source to enter the air intake chamber 240. Specifically, the second air intake channel 250 connects the air intake chamber 150 and the air intake chamber 240. Since the air intake chamber 150 is connected to an external air source, gas from an external air source can enter the air intake chamber 240.

[0062] The intake device 300 includes a piston diaphragm assembly 310, a first one-way element 340, and a drive assembly 330.

[0063] The piston diaphragm assembly 310 is disposed in the intake chamber 240. The piston diaphragm assembly 310 includes at least one bowl 311. The opening of the bowl 311 faces the gas storage chamber 131. The bowl 311 and the inner wall of the intake chamber 240 form a pump chamber 320. The first air intake channel communicates with the pump chamber 320. Thus, when the volume of the pump chamber 320 is reduced, the gas in the pump chamber 320 can be driven into the gas storage chamber 131.

[0064] The first one-way component 340 is disposed in the first air intake channel to control the gas in the pump chamber 320 to enter the gas storage chamber 131 in one direction. The drive assembly 330 is drivenly connected to 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 enters the gas storage chamber 131 through the first air intake channel to inflate the gas storage chamber 131.

[0065] According to a specific embodiment of the present invention, the piston diaphragm assembly 310 can be driven by the driving component 330 to drive the bowl 311, so that the gas in the suction chamber 240 enters the gas storage chamber 131, and the gas can only flow into the gas storage chamber 131 in one direction by the first one-way member 340, thereby realizing the gas storage function.

[0066] It is understandable that the drive component 330 can be a motor or other power device that can achieve the driving effect.

[0067] 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 first air intake channel. It can also be a structure with a membrane. Specifically, the area of ​​the membrane is larger than the cross-sectional area of ​​the first air intake channel. The position and area of ​​the membrane restrict the membrane to deform only towards the side of the air storage chamber 131, thereby exposing the first air intake channel.

[0068] refer to Figure 2-6In some specific embodiments of the present invention, the first housing 100 further includes a second housing 200, which forms an air intake chamber 240. Specifically, the second housing 200 may be a part of the first housing 100, integrally formed with the first housing 100, or it may be an independent housing structure assembled within the first housing 100. The second housing 200 has an air outlet 211 on its side wall near the air storage chamber 131, and the air storage component 130 has an air inlet 133 on its side wall near the second housing 200. The air inlet 133 and the air outlet 211 are sequentially connected to form a first air intake channel.

[0069] refer to Figure 13 In some specific embodiments of the present invention, the second housing 200 includes a cylindrical portion 220, a partition plate 221 is provided radially on the cylindrical portion 220, and a cylinder 222 is provided on the partition plate 221. Specifically, the cylinder 222 extends outward in a direction away from the gas storage cavity 131, the cylinder 222 is hollow, and the cylinder 222 communicates with the air outlet 211. Specifically, the end of the cylinder 222 near the gas storage cavity 131 can be completely hollowed out, in which case the end of the air outlet 211 is directly connected to the space inside the cylinder 222. Alternatively, the end of the cylinder 222 near the gas storage cavity 131 can still be blocked by the partition plate 221, and an opening penetrating the partition plate 221 is provided on the partition plate 221 enclosing the cylinder 222. The opening corresponds to the air outlet 211, thereby enabling the air outlet 211 to communicate with the space inside the cylinder 222.

[0070] 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.

[0071] It is understandable that when the end of the cylinder 222 near the gas storage chamber 131 is completely hollowed out, the bowl 311, the cylinder 222, and the wall of the second shell 200 form a pump chamber 320.

[0072] Therefore, when the bowl 311 is driven to slide back and forth in the cylinder 222, the volume of the pump chamber 320 changes, thereby completing the inflation process. It can be understood that if the bowl 311 is made of a deformable material such as rubber, when the bowl 311 moves to abut against the partition plate 221, it can continue to deform towards the air storage chamber 131, and the gas in the bowl 311 is also input into the air storage chamber 131.

[0073] refer to Figure 6In some specific embodiments of the present invention, the shower head is also provided with an air replenishment channel. When the air intake device 300 continuously inflates the air storage chamber 131, 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 the gas in the pump chamber 320 is sufficient when inflating again.

[0074] 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.

[0075] In some embodiments, the gas replenishment channel can be provided on the bowl portion 311. Specifically, the gas replenishment channel penetrates the peripheral wall of the bowl portion 311. In this embodiment, the cross-sectional area of ​​the gas replenishment channel can be designed to be extremely small, and a first one-way component 340 (such as a check valve) that can be opened in one direction with only a small pressure is selected. Thus, when the pump chamber 320 shrinks, most of the gas enters the gas storage chamber 131 through the first air intake channel, and only a very small amount of gas can enter the suction chamber 240 through the gas replenishment channel. When the pump chamber 320 recovers, the gas storage chamber 131 is closed due to the first one-way component 340, and only the gas in the suction chamber 240 can enter the pump chamber 320 through the gas replenishment channel.

[0076] refer to Figure 3 In some specific embodiments of the present invention, the second housing 200 includes an upper cover assembly and a lower cover 230, wherein an air outlet 211 and an air replenishment channel are disposed on the upper cover assembly, and a second air inlet channel 250 is disposed on the upper cover assembly and / or the lower cover 230.

[0077] Understandably, the air replenishment channel is also designed with a suitable cross-sectional area to meet the air replenishment requirements.

[0078] refer to Figure 3 , Figure 12-13 In some specific embodiments of the present invention, the air replenishment channel includes an air replenishment groove 212 and an air replenishment hole 2211. The upper cover assembly includes an upper cover 210 and a cylindrical portion 220. The cylindrical portion 220 has a hollow design, and its two ends are open and connected to the upper cover 210 and the lower cover 230, respectively. The upper cover 210 is provided with an air outlet 211 and an air replenishment groove 212. Specifically, the air outlet 211 penetrates the upper cover 210, and the air replenishment groove 212 (not penetrating the upper cover 210) is hollowed out on the side of the upper cover 210 facing away from the air storage chamber 131. The cylindrical portion 220 extends a partition plate 221 along its own radial direction, and the air replenishment hole 2211 is disposed on the partition plate 221 and penetrates the partition plate 221.

[0079] 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.

[0080] In some specific embodiments of the present invention, the shower head 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.

[0081] In this embodiment, due to the provision of a second one-way component, when the pump chamber 320 fills the gas storage chamber 131 with gas, the gas cannot enter the intake chamber 240 from the gas replenishment channel. Therefore, the cross-sectional area of ​​the gas 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 gas replenishment speed.

[0082] It is understood that the second one-way component can be a check valve, a shut-off valve, etc., and it can be installed in the air supply groove 212 or in the air supply hole 2211; there is no limitation here. Alternatively, the second one-way component can also be 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. The diaphragm 314 can be installed in different positions. When the diaphragm 314 is installed in the air supply groove 212, the area of ​​the diaphragm 314 is larger than the air passage cross-sectional area of ​​the air supply groove 212; when the diaphragm 314 is installed in the air supply hole 2211, the area of ​​the diaphragm 314 is larger than the air passage cross-sectional area of ​​the air supply hole 2211.

[0083] refer to Figure 6 In some specific embodiments of the present invention, the bowl portion 311 is at least partially made of a deformable material, and a membrane portion 312 is provided on the open side of the bowl portion 311, which is sandwiched between the upper cover 210 and the cylindrical portion 220. In this case, the bowl portion 311 is essentially fastened to the upper cover 210, and together with the upper cover 210, forms the pump cavity 320. It is 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.

[0084] According to an embodiment of the present invention, at this time, since the membrane portion 312 on its open side 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 deforms, 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 gas storage chamber 131, the shape of the bowl portion 311 is restored, and gas enters the pump chamber 320 from the gas replenishment channel.

[0085] In some specific embodiments of the present invention, the partition plate 221 also includes a cylinder 222, which is connected to the air outlet 211. The bowl portion 311 is disposed in the cylinder 222. When the drive assembly 330 moves, the membrane portion 312 of the bowl portion 311 is clamped. At this time, the main body of the bowl portion 311 deforms in the cylinder 222, thereby changing the volume of the pump chamber 320.

[0086] In some embodiments, 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.

[0087] 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.

[0088] refer to Figure 6 and Figure 10 In some specific embodiments of the present invention, the piston membrane assembly 310 is provided with N bowls 311, where N is an integer greater than or equal to 2, and can be 3, 4 or more. The N bowls 311 are connected by membrane sections 312, which can be interconnected to form a membrane structure with a large area. The N bowls 311 are disposed in the membrane sections 312, and the number of cylinders 222 is the same as the number of bowls 311. Specifically, the membrane section 312 with N bowls 311 is disposed on the side of the partition plate 221 near the upper cover 210, and the skirt of the membrane section 312 is clamped between the cylinder section 220 and the upper cover 210. The N bowls 311 are arranged in a one-to-one correspondence with the N cylinders 222.

[0089] Understandably, the top cover 210 also has N air outlets 211 and air replenishment grooves 212, the air storage chamber 131 is provided with N air inlets 133, 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.

[0090] refer to Figure 10-11In some specific embodiments of the present invention, the membrane portion 312 is provided with a vent 313 corresponding to the gas supply hole 2211, thereby preventing the membrane portion 312 from blocking the gas flow between the gas supply hole 2211 and the gas supply groove 212. The vent 313 can be configured with a large aperture, thereby encompassing all N gas supply holes 2211. Alternatively, the vent 313 can be configured as N smaller aperture holes, corresponding one-to-one with each gas supply hole 2211.

[0091] refer to Figure 10-11 In some specific embodiments of the present invention, the second one-way member is disposed in the vent 313.

[0092] Specifically, the second one-way component can be a one-way valve, a check valve, or a plate or diaphragm that can only be folded in one direction, as long as it allows gas to enter the pump chamber 320 from the gas supply channel in one direction.

[0093] refer to Figure 10-11 In some specific embodiments of the present invention, 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 supply hole 2211 through the second connecting portion 315. When the diaphragm 314 is connected to the air supply hole 2211, the specific position of the diaphragm 314 is on the side of the air supply hole 2211 close to the air supply 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 supply 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 supply hole 2211, the diaphragm 314 can be folded with the second connecting portion 315 as the axis.

[0094] In this embodiment of the invention, when gas enters the replenishment channel from the intake chamber 240, the gas can drive the diaphragm 314 to fold in the direction close to the pump chamber 320, thereby opening the vent 313 or the replenishment port 2211. When gas enters the replenishment groove 212 from the pump chamber 320, the diaphragm 314 is covered on the vent 313 or the replenishment port 2211 under the drive of the gas, cutting off the connection between the replenishment groove 212 and the replenishment port 2211, so that the gas cannot enter the intake chamber 240, thereby restricting the flow direction of the gas.

[0095] 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.

[0096] refer to Figure 3In some specific embodiments of the present invention, the drive assembly 330 includes a drive member 331, a drive shaft 332 and a drive disk 333. The drive disk 333 is drivenly connected to the bowl portion 311. The drive member 331 and the drive disk 333 are respectively disposed at both ends of the drive shaft 332. Thus, the drive member 331 can use the drive shaft 332 to move the drive disk 333, thereby controlling the movement and / or deformation of the bowl portion 311.

[0097] It is understandable that the drive assembly 330 can be entirely disposed in the intake chamber 240, or the drive component 331 can be disposed in the intake chamber 150, the drive disk 333 can be disposed in the intake chamber 240, and the drive shaft 332 can pass through the lower cover 230 to connect the two.

[0098] It is understood that the drive component 331 may include a motor, and the drive shaft 332, driven by the motor, causes the drive disc 333 to reciprocate along the axial direction of the drive shaft 332, thereby driving the bowl portion 311 to move and / or deform. In this case, the drive assembly 330 can be located in the air intake chamber 150 or in the air intake chamber 240. The drive component 331 can be directly connected to a power supply, or it can be connected to a hydroelectric power generation device, using the water from the showerhead to power the motor.

[0099] 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 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.

[0100] refer to Figure 3 , Figure 14-15 In some specific embodiments of the present invention, the lower 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 portion 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. The first shaft segment 3321 is partially inserted into the first shaft hole 231, and the second shaft segment 3322 is inserted into the first shaft hole 231. 322 is located in the intake chamber 240. The portion of the first shaft segment 3321 facing away from the second shaft segment 3322 is exposed in the intake chamber 150 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 intake chamber 240 and pivotally connected to the second shaft segment 3322. Specifically, the drive disk 333 is roughly disc-shaped. 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.

[0101] 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.

[0102] In this embodiment of the invention, when the shower head 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 storage chamber 131. 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.

[0103] It should be noted here 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 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.

[0104] refer to Figure 3-6 , Figure 16 In some specific embodiments of the present invention, the first housing 100 further includes a water passage cavity 160. Specifically, the water outlet cover 140 includes a water outlet cover 142 and a water sealing plate 141. 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. An annular plate 1411 is provided on the side of the water sealing plate 141 near the second housing 200. The water sealing plate 141 is connected to the second housing 200 through the annular plate 1411. The water inlet channel 121 is connected to the water outlet channel 143 by forming a water passage 160. The water sealing plate 141 is provided with a water passage hole 1413 connecting the water passage 160 and the water outlet channel 143 in the part surrounding the annular plate 1411. It can be understood that in the embodiment of the present invention, "the water inlet channel 121 is connected to the water outlet channel 143" means that the water inlet channel 121 is connected to the water passage 160 and the water outlet channel 143 is connected. The water flow in the water inlet channel 121 can pass through the water passage 160 and then enter the water outlet channel 143.

[0105] 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.

[0106] 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.

[0107] In this embodiment of the invention, the drive component 330 can use the water flow energy from the showerhead to complete the inflation and replenishment process without additional energy consumption. The user can complete the air storage process simultaneously during the shower without any additional operation.

[0108] refer to Figure 10 and Figure 14 In some specific embodiments of the present invention, the drive disk 333 is provided with N first hinge members 3331, and the cup portion 311 is provided with a second hinge member 316 on the side facing away from the pump cavity 320. The drive disk 333 and the cup portion 311 are connected by the first hinge members 3331 and the second hinge members 316. The first hinge members 3331 are arranged in a circular array on the drive disk 333, with the connection point between the drive disk 333 and the drive shaft 332 as the center.

[0109] Specifically, one of the first hinge member 3331 and the second hinge member 316 can be an annular sleeve, and the other can be a ball head. The annular sleeve can be fitted onto the ball head, thereby realizing the drive. The first hinge member 3331 and the second hinge member 316 can also both be fasteners or other connecting structures, as long as they can realize the connection function. No specific limitation is made here.

[0110] refer to Figure 14 In some specific embodiments of the present invention, the drive disk 333 is bowl-shaped and its opening faces away from the piston membrane assembly 310.

[0111] In a specific embodiment of the present invention, the bowl-shaped design of the drive disk 333, compared to the flat drive disk 333, results in a greater distance between the drive disk 333 and the air storage cavity 131 in the initial state. Furthermore, when the drive disk 333 moves away from the air storage cavity 131, the other side of the drive disk 333 also has a greater stroke before interfering with the inner wall of the suction cavity 240. Therefore, the bowl portion 311 travels further during the air replenishment process. Thus, through the cooperation between the first hinge 3331 and the second hinge 316, the bowl portion 311 can be stretched, moved, and / or deformed to a greater extent in the direction away from the air storage cavity 131, allowing more gas to be drawn in and input into the air storage cavity 131, making the air storage process faster and more efficient.
