Description

Technical Field

[0001] This invention relates to the technical field of bathroom fixtures, and in particular to an electric shower head. Background Technology

[0002] A shower head, also known as a shower spray head, is a bathroom fixture that connects to a water source via pipes and disperses water into a uniform spray pattern for daily bathing and cleaning. Modern shower heads have evolved from simple water outlets to various forms including thermostatic, pressurized, multi-functional, and intelligent control models.

[0003] With technological advancements, showerheads have evolved from simply spraying water to now being motor-driven and equipped with massage functions. For example, Chinese patent document CN214554519U discloses an electric showerhead, which includes a shower head and a handle. The shower head comprises a main body and a functional brush head disposed on one side of the main body. The functional brush head is rotatable relative to the main body. A motor mounting base is provided within the main body, dividing it into an isolated receiving cavity and a water flow cavity. The receiving cavity houses an ultrasonic motor, which drives the functional brush head to oscillate back and forth within a certain angle range. One end of the handle is connected to the shower head, and the other end can be connected to an external water pipe. The handle contains a water flow channel communicating with the water flow cavity. Thus, by using a motor to drive the functional brush head to oscillate back and forth within a certain angle range, the showerhead provides both showering and massage functions.

[0004] However, existing electric showerheads have the following shortcomings in practical use: the functional brush head covers the front of the showerhead body and is driven by a motor to oscillate in the middle. Therefore, during actual use, the functional brush head uses the motor connection point as the fulcrum. When massaging with the edge of the functional brush head, the large coverage area causes the brush head to experience eccentric force distribution. Over time, this can easily lead to loosening of the transmission mechanism connecting the functional brush head and the motor. Secondly, since users need to apply shower gel to their backs during showering, existing electric showerheads lack this function. Therefore, to meet users' needs for a multi-functional showerhead and improve the stability of the shower massage, the electric showerhead of this application is proposed. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an electric shower head that can effectively improve massage stability while also having the function of applying shower gel.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] An electric shower head includes: The shower head body has at least two brush heads rotatably mounted on its front side. A rotary drive component is provided inside the shower head body and is connected to each of the brush heads. Several water outlet holes are also provided on the front side of the shower head body. A water inlet cavity is provided inside the shower head body and communicates with each of the water outlet holes. The water inlet cavity is used to communicate with an external water pipe. The pump body is disposed inside the shower head body, and the shower head body also has a liquid storage chamber. One of the brush heads has an injection hole that extends from the inside of the shower head body to the outside of the shower head body. The pump body is connected to the liquid storage chamber and the injection hole respectively.

[0008] Optionally, the rotary drive component includes a motor and a gear set. The motor is disposed inside the shower head body, and the gear set is rotatably disposed inside the shower head body. The gear set is connected to the output shaft of the motor and each of the brush heads respectively.

[0009] Optionally, the gear set includes a main gear and at least two subsidiary gears that mesh with the main gear. The main gear and each subsidiary gear are rotatably disposed within the shower head body, and the main gear is connected to the output shaft of the motor, while the subsidiary gears are connected to each of the brush heads.

[0010] Optionally, the rotary drive component further includes a screw, which is rotatably disposed within the shower head body, and one end of the screw is connected to the output shaft of the motor, and the screw meshes with the main gear.

[0011] Optionally, the outer peripheral wall of the brush head is provided with a plurality of teeth for meshing with a gear set, and at least one protrusion is provided on the end face of the brush head that passes through the front side of the shower body for contact with the user.

[0012] Optionally, a handle is adjustablely hinged to one end of the shower head body, and a water inlet is provided at the end of the handle away from the shower head body. The water inlet is used to connect an external water pipe and is connected to the water inlet cavity.

[0013] Optionally, a valve body is provided at one end of the handle near the shower head body. The valve body has a valve cavity and an inlet and an outlet end that are respectively connected to the valve cavity. The inlet end is connected to the inlet hole, and the outlet end is connected to the inlet chamber. A valve core is slidably disposed in the valve cavity. The valve core has a through hole. A knob is also rotatably disposed on the shower head body. The knob is screwed to the valve core. When the knob is rotated under force, it drives the valve core to slide back and forth in the valve cavity, thereby making the overlapping area between the through hole and the inlet and outlet ends adjustable.

[0014] Optionally, a sealing ring is fitted on the valve core, and the sealing ring is in close contact with the inner wall of the valve cavity.

[0015] Optionally, a locking button is rotatably provided on one end of the shower head body near the handle, and the locking button is screwed to the handle. A retaining block is also rotatably provided inside the shower head body. The retaining block has a plurality of first retaining teeth arranged in a circular pattern, and the handle has a plurality of second retaining teeth arranged in a circular pattern. The locking button is used to rotate under force to drive each of the first retaining teeth on the retaining block to engage or disengage with each of the second retaining teeth.

[0016] Optionally, a holding spring is also provided between the locking button and the clamping block. The holding spring is used to push the clamping block so that the first clamping tooth tends to approach and engage with the second clamping tooth.

One of the brush heads has an injection hole extending from the interior of the shower head body to the exterior. The pump body is connected to both the liquid storage chamber and the injection hole. Thus, the electric shower head of this application can spray water for showering while simultaneously squeezing out cleaning liquids such as shower gel onto areas difficult for the user to reach, such as the back. Furthermore, the matrix-distributed brush heads can withstand uneven pressure during use, resulting in a stable structure and rich functionality. Attached Figure Description

[0021] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention.

[0022] like Figures 1 to 3As shown, an electric shower head 10 includes a shower head body 100 and a pump body 200. At least two brush heads 300 are rotatably disposed on the front side of the shower head body 100. A rotary drive 400 is disposed inside the shower head body 100 and is connected to each brush head 300. A plurality of water outlet holes 121 are also opened on the front side of the shower head body 100. A water inlet cavity 122 communicating with each water outlet hole 121 is opened inside the shower head body 100 and is used to communicate with an external water pipe. The pump body 200 is disposed inside the shower head body 100, and a liquid storage cavity 161 is also opened inside the shower head body 100. One of the brush heads 300 is provided with an injection hole 310, which extends from the inside of the shower head body 100 to the outside of the shower head body 100. The pump body 200 is connected to the liquid storage cavity 161 and the injection hole 310 respectively.

[0023] It should be noted that the side of the shower head body 100 used for water dispensing is the front side, and the side opposite to the water dispensing side is the back side. The brush head 300 and the water outlet 121 are both located on the front side of the shower head body 100. The rotary drive 400 is installed inside the shower head body 100 and is used to drive each brush head 300 to rotate. Thus, the rotating drive 400 drives each brush head 300 to rotate. Since the brush heads 300 are spaced apart on the front side of the shower body 100, in actual use, compared to the existing technology where functional brush heads cover a large area but only the central position provides force support, this application, by setting multiple brush heads 300 into a matrix structure, ensures that when the shower body 100 is tilted and applied to the user, that is, some brush heads 300 receive greater pressure, while others receive less pressure or are even separated from the user. At this time, it can be ensured that the brush heads 300 in contact with the user maintain good and stable rotational massage, thus providing better stability. Furthermore, an independent liquid storage chamber 161 is provided inside the shower body 100, and the liquid storage chamber 161 is connected to the injection hole 310 through the pump body 200. Thus, when a user needs to apply cleaning liquid, such as shower gel, to areas of their back that are difficult to reach, the front of the electric shower head 10 can be positioned towards the user's back, and the pump 200 can be activated to squeeze the shower gel from the reservoir 161 out of the injection hole 310, making it convenient to use. Furthermore, the water inlet chamber 122 is used to connect to an external standard water pipe, allowing external water to enter the water inlet chamber 122 and then spray out from each water outlet 121. Therefore, the electric shower head 10 of this application can spray water for showering while simultaneously squeezing cleaning liquids such as shower gel onto areas of the user's back that are difficult to reach. Moreover, the matrix-distributed brush heads 300 can withstand uneven pressure, resulting in a stable structure and rich functionality.

[0024] like Figure 3 , Figure 4As shown, in one embodiment, the rotary drive 400 includes a motor 410 and a gear set. The motor 410 is disposed inside the shower head body 100, and the gear set is rotatably disposed inside the shower head body 100. The gear set is connected to the output shaft of the motor 410 and each brush head 300 respectively.

[0025] It should be noted that this application provides an embodiment in which the motor 410 is used as the power output source. The output shaft of the motor 410 is connected to each brush head 300 via a gear set as an intermediate driving component. This allows the motor 410 to simultaneously drive multiple brush heads 300 to rotate for simultaneous massage through the engagement of the gear set.

[0026] like Figure 3 , Figure 4 As shown, in one embodiment, the gear set includes a main gear 420 and at least two sub-gears 430 that mesh with the main gear 420. The main gear 420 and each sub-gear 430 are rotatably disposed within the shower head body 100, and the main gear 420 is connected to the output shaft of the motor 410, while the sub-gears 430 are connected to each brush head 300.

[0027] It should be noted that this embodiment can be used when multiple brush heads 300 need to be classified into different groups, and the brush heads 300 in different groups need to rotate at different speeds. Specifically, the main gear 420 and each of the sub-gears 430 are rotatably mounted inside the shower body 100, and each sub-gear 430 meshes with the main gear 420. Thus, when the motor 410 drives the main gear 420 to rotate, the sub-gears 430 are simultaneously driven to rotate. By specifically setting the number of meshing gears, diameters, and other factors between the main gear 420 and each sub-gear 430, different rotational speeds of the different sub-gears 430 can be specifically set. Therefore, after dividing the brush heads 300 into different groups as needed, the rotational speeds of the brush heads 300 in different groups can be made different. More specifically, the diameters of the brush heads 300 in different groups can be designed to be different sizes. For example, for ease of description, this application will use a specific embodiment where the diameter of the brush head 300 located at the center of the shower head body 100 is larger than the diameter of the brush heads 300 distributed around it. That is, the brush head 300 located at the center of the front side of the shower head body 100 is a separate group, while the brush heads 300 distributed around it are another separate group. Correspondingly, two gears 430 are provided, one of which drives the brush head 300 located at the center of the front side of the shower head body 100 to rotate, and the other gear 430 drives the brush heads 300 distributed around it to rotate.

[0028] like Figure 3 , Figure 4As shown, in one embodiment, the rotary drive 400 further includes a screw 440, which is rotatably disposed within the shower head body 100, and one end of the screw 440 is connected to the output shaft of the motor 410, and the screw 440 meshes with the main gear 420.

[0029] It should be noted that the screw 440 is rotatably installed inside the shower head body 100, and the screw 440 meshes with the main gear 420. This creates a worm gear-like structure between the screw 440 and the main gear 420. This ensures that the motor 410 can stably drive the main gear 420 to rotate, and also achieves unidirectional transmission.

[0030] like Figures 5 to 7 As shown, in one embodiment, the outer peripheral wall of the brush head 300 is provided with a plurality of gear teeth 320 for meshing with a gear set, and at least one protrusion 330 is provided on the end face of the brush head 300 that passes through the front side of the shower body 100 for contact with the user.

[0031] It should be noted that the brush head 300 and the shower body 100 are rotatably connected. To facilitate the rotation of the brush head 300, gear teeth 320 are provided on the outer peripheral wall of the brush head 300, enabling the gear set to stably drive the brush head 300 to rotate. Furthermore, at least one protrusion 330 is provided on the end face of the brush head 300 extending from the front side of the shower body 100. The protrusion 330 rotates with the brush head 300 to provide massage and cleaning for the user.

[0032] like Figure 7 As shown, in one embodiment, a protrusion 330 is provided, and the protrusion 330 is inclined relative to the rotation axis of the brush head 300.

[0033] It should be noted that in this embodiment, the protrusion 330 is designed as a finger-like structure, that is, the diameter of the protrusion 330 is the same as the diameter of a human finger, and the protrusion 330 is inclined, with one end of the protrusion 330 located at the rotation center of the brush head 300. Thus, when the brush head 300 rotates, the inclined protrusion 330 rotates along with it, allowing a single protrusion 330 to massage and clean the user.

[0034] like Figure 5 , Figure 6 As shown, in one embodiment, there are two or more protrusions 330, and each protrusion 330 is distributed at equal angles around the axis of rotation of the brush head 300.

[0035] It should be noted that in this embodiment, when there are two or more protrusions 330, the diameter of each protrusion 330 is set to be smaller than the diameter of a single protrusion 330, so that the protrusions 330 can be spaced out and cover the end face of the brush head 300 that protrudes from the front side of the shower head body 100. In one embodiment, the number of protrusions 330 is set to 2 to 16. For ease of understanding, this application provides embodiments in which the protrusions 330 are set to one, ten, and twelve, and describes them with corresponding figures. In this way, multiple protrusions 330 are set to rotate with the brush head 300, thereby enabling massage cleaning for the user.

[0036] In one embodiment, the protrusion 330 is made of soft rubber. It should be noted that since the protrusion 330 needs to directly contact the user for massage, it is made of soft rubber, such as silicone. Because the outer peripheral wall of the brush head 300 needs to have a rigid toothed structure 320, and its end face extending from the front side of the shower head body 100 needs to have a soft protrusion 330 structure, to achieve both of these characteristics, the brush head 300 is integrally injection molded from different plastic materials.

[0037] like Figure 6 , Figure 8 As shown, in one embodiment, the brush head 300 includes a rotating block 340 and an external block 350. The rotating block 340 is rotatably disposed inside the shower body 100, and one end of the rotating block 340 extends out from the front side of the shower body 100. The external block 350 is disposed on the end of the rotating block 340 that extends out from the front side of the shower body 100. Each tooth 320 is located on the outer peripheral wall of the rotating block 340, and each protrusion 330 is located on the external block 350.

[0038] It should be noted that the rotating block 340 is stably rotatably installed within the shower head body 100, while the external block 350 and the rotating block 340 have a detachable installation structure. For example, a first polyhedron 341, such as a tetrahedron, is provided on the end of the rotating block 340 that protrudes from the front side of the shower head body 100. Multiple claws 342 are provided on the end face of the first polyhedron 341. A first polyhedron face 351, such as a tetrahedron face, is provided at the center of the external block 350, which is adapted to the first polyhedron 341. The maximum diameter formed by each claw 342 is larger than the inner diameter of the first polyhedron face 351. Thus, after each claw 342 passes through the first polyhedron face 351, and the first polyhedron 341 then passes through the first polyhedron face 351, the first polyhedron face 351 clamps and fixes each claw 342 because the maximum outer diameter formed by the claws 342 is larger than the first polyhedron face 351. This ensures that the external block 350 and the rotating block 340 are clamped and fixed. Thus, when the protrusion 330 wears out, the protrusion 330 can be quickly replaced by replacing the outer block 350. Specifically, by applying an external force to bring each claw 342 closer together, the outer block 350 can be removed from the rotating block 340.

[0039] like Figure 1 As shown, in one embodiment, the brush head 300 is divided into a central brush head 300a and peripheral brush heads 300b according to different installation positions. The central brush head 300a is located at the center of the front side of the shower head body 100, and there is only one central brush head 300a. Multiple peripheral brush heads 300b are arranged, and each peripheral brush head 300b is distributed in a circular, equidistant manner around the central brush head 300a. Thus, the central brush head 300a forms a separate group, and the peripheral brush heads 300b form a collective group. Correspondingly, two gears 430 are provided, one of which is connected to the central brush head 300a, and the other is connected to the peripheral brush heads 300b. Further, in one embodiment, at least one indirect gear 450 is provided between any two adjacent peripheral brush heads 300b, and the indirect gear 450 is used to connect with the two adjacent peripheral brush heads 300b. For example, two indirect gears 450 are provided between any two adjacent peripheral brush heads 300b. In this way, each peripheral brush head 300b and the indirect gear 450 cooperate to form a structure that rotates together. This allows the gear 430 to drive all peripheral brush heads 300b to rotate simultaneously by meshing with only one of them.

[0040] like Figure 2 , Figures 9 to 12As shown, in one embodiment, the shower head body 100 includes a main housing 110, a water storage shell 120, and a face shell 130. The main housing 110 has an equipment cavity 111. The rotary drive 400 and the pump body 200 are both located in the equipment cavity 111. The water storage shell 120 is fastened to the front side of the main housing 110 so that the water storage shell 120 and the main housing 110 together form a water inlet cavity 122. The face shell 130 is fastened to the side of the water storage shell 120 away from the main housing 110 so that the face shell 130 and the water storage shell 120 together form a brush head cavity 131. The brush heads 300 are all rotatably disposed in the brush head cavity 131, and each protrusion 330 passes through the face shell 130. The water outlet 121 is located on the water storage shell 120, and the water outlet 121 passes through the face shell 130.

[0041] It should be noted that the water storage shell 120 is fastened and fixed to the main shell 110 so that the water storage shell 120 and the main shell 110 enclose a water inlet cavity 122. The face shell 130 is then fastened and fixed to the outer wall of the water storage shell 120 so that the face shell 130 and the water storage shell 120 enclose a brush head cavity 131. The water outlet 121 passes through the face shell 130 and extends to the surface of the face shell 130, thus allowing water to be sprayed outwards from the water inlet cavity 122 through the water outlet 121. The brush head 300 is installed inside the brush head cavity 131, and the protrusion 330 passes through the face shell 130 and extends to the outer side of the face shell 130. The rotary drive 400 is installed inside the device cavity 111 of the main shell 110, and the rotary drive 400 passes through the main shell 110 and the water storage shell 120 to extend into the brush head cavity 131 and connect with the brush head 300. Specifically, each gear 430 passes through the main housing 110 and the water storage shell 120 to extend into the brush head cavity 131 and connect with the brush head 300. A sealing ring is fitted onto each gear 430, and the sealing ring is in close contact with the main housing 110 and the water storage shell 120 to ensure a tight seal as the gear 430 passes through them. Furthermore, to ensure the sealing of the water inlet cavity 122 formed between the main housing 110 and the water storage shell 120, a sealing ring is also installed at the connection point between the main housing 110 and the water storage shell 120, or they are ultrasonically welded together to form a single structure.

[0042] like Figure 2 , Figure 3 , Figure 9 , Figure 12 , Figure 13 As shown, in one embodiment, the shower head body 100 further includes a liquid injection block 140, which is disposed on the water storage shell 120. One end of the liquid injection block 140 passes through the liquid injection hole 310 of the central brush head 300a, and the other end of the liquid injection block 140 passes through the main housing 110 to communicate with the pump body 200.

[0043] It should be noted that the central brush head 300a is driven to rotate relative to the liquid injection block 140, which has a liquid outlet hole 141. One end of the liquid outlet hole 141 is connected to the pump body 200, and the other end passes through the liquid injection hole 310 to extend to the surface of the faceplate 130. In this way, the pump body 200 sprays cleaning liquids such as shower gel outward through the liquid outlet hole 141 and the liquid injection hole 310.

[0044] like Figure 2 As shown, in one embodiment, the shower head body 100 also includes a drive housing 150, in which the motor 410, main gear 420, branch gear 430, and screw 440 are all disposed.

[0045] It should be noted that, in order to facilitate modular production and improve production efficiency, after the motor 410, main gear 420, dividing gear 430, and screw 440 are installed inside the drive housing 150, during assembly, it is only necessary to install the drive housing 150 inside the main housing 110. One end of each dividing gear 430 protrudes from the drive housing 150, allowing the dividing gear 430 to connect with the brush head 300.

[0046] like Figure 2 As shown, in one embodiment, the shower head body 100 also includes a liquid storage shell 160, which is disposed inside the main housing 110. The liquid storage cavity 161 is located inside the liquid storage shell 160. The liquid storage shell 160 is provided with an filling hole 162, which passes through the back side of the main housing 110 to communicate with the outside.

[0047] It should be noted that, in addition to directly creating the liquid storage chamber 161 within the main housing 110, the liquid storage chamber 161 can also be created on the liquid storage shell 160, and then the liquid storage shell 160 can be installed within the main housing 110. The liquid storage chamber 161 is connected to the pump body 200 via a connecting pipe. Furthermore, the pump body 200 is connected to the outlet hole 141 via another connecting pipe, allowing cleaning liquids such as shower gel within the liquid storage chamber 161 to be smoothly sprayed out from the outlet hole 141. Further, to facilitate the filling of the cleaning liquid into the liquid storage chamber 161, the liquid storage shell 160 is provided with a filling hole 162, which extends from the back side of the main housing 110 to the outside of the main housing 110. In one embodiment, a screw cap 170 is screwed onto the filling hole 162, thus sealing the liquid storage chamber 161 using the screw cap 170.

[0048] like Figure 2As shown, in one embodiment, the shower head body 100 further includes a back shell 180, which is fastened to the rear side of the main housing 110, so that the main housing 110 and the back shell 180 enclose a device cavity 111. Thus, the back shell 180 and the main housing 110 are detachable and installable, which facilitates the installation of the drive housing 150, pump body 200, liquid storage housing 160, etc., in the device cavity 111.

[0049] like Figure 1 , Figure 2 As shown, in one embodiment, a handle portion 500 is tunably hinged to one end of the shower head body 100. A water inlet hole 510 is provided at the end of the handle portion 500 away from the shower head body 100. The water inlet hole 510 is used to connect an external water pipe and is connected to the water inlet chamber 122.

[0050] It should be noted that, in order to further improve the convenience of actual use of the electric shower head 10, specifically, to make it easier for users to operate the shower head body 100 to massage their backs and apply cleaning liquid, the solution of this embodiment is designed. Specifically, one end of the handle portion 500 is hinged to one end of the shower head body 100, that is, one end of the handle portion 500 is hinged and fixed to one end of the main housing 110. The included angle formed between the handle portion 500 and the main housing 110 is adjustable, specifically, the angle adjustment range is 90°~180°, so that the included angle between the handle portion 500 and the main housing 110 can be a right angle at the minimum and a flat angle at the maximum. A water inlet hole 510 is provided at the end of the handle portion 500, that is, the end away from the main housing 110. When the water inlet hole 510 is connected to an external water pipe, water can flow into the water chamber 122.

[0051] like Figure 2 , Figures 14 to 18 As shown, in one embodiment, a valve body 610 is provided at one end of the handle portion 500 near the shower head body 100. The valve body 610 has a valve cavity 611 and an inlet end 612 and an outlet end 613 respectively communicating with the valve cavity 611. The inlet end 612 communicates with the inlet hole 510, and the outlet end 613 communicates with the inlet chamber 122. A valve core 620 is slidably disposed in the valve cavity 611. A through hole 621 is provided on the valve core 620. A knob 630 is also rotatably disposed on the shower head body 100. The knob 630 is screwed to the valve core 620. When the knob 630 is rotated under force, it drives the valve core 620 to slide back and forth in the valve cavity 611, so that the overlapping area between the through hole 621 and the inlet end 612 and the outlet end 613 is adjustable.

[0052] It should be noted that the water inlet 510 is used to connect an external water pipe, therefore the water inlet volume of the water inlet 510 is a fixed value relative to the electric shower head 10. To allow the water spray speed in the outlet 121 to be adjustable to meet different user needs, this embodiment's solution is implemented. Specifically, the valve body 610 is fixedly installed at the junction of the handle portion 500 and the main housing 110. The valve body 610 is horizontally installed within the handle portion 500, and has a valve cavity 611 along its axial direction. The valve body 610 also has a water inlet end 612 and a water outlet end 613 along its radial direction. Both the water inlet end 612 and the water outlet end 613 communicate with the valve cavity 611, with the water inlet end 612 facing the handle portion 500 and the water outlet end 613 facing the main housing 110. Furthermore, the water inlet end 612 and the water outlet end 613 are aligned with each other. The valve core 620 is slidably mounted within the valve cavity 611. A through hole 621 is radially formed on the valve core 620. Thus, when the valve core 620 slides along the valve cavity 611, the through hole 621 can communicate with the inlet end 612 and the outlet end 613, or be misaligned and closed with the inlet end 612 and the outlet end 613, or the overlapping area between the through hole 621 and the outlet end 613 can be variable. Water sequentially passes through the inlet end 612, the through hole 621, and the outlet end 613. By changing the sliding position of the valve core 620 in the valve cavity 611, the flow rate can be adjusted. The adjustable range includes complete closure, maximum water flow, and any flow rate in between. It should be noted that the flow rate and flow rate mentioned here refer to the volume of water flowing per unit time. Furthermore, to facilitate changing the position of the valve core 620, a knob 630 is rotatably mounted on the main housing 110, wherein the knob 630 is screwed to the valve core 620. Thus, applying torque to the knob 630 causes the valve core 620 to slide axially within the valve cavity 611. In one embodiment, a guide hole 614 is provided in the valve body 610 along the sliding direction of the valve core 620, and a guide post 622 is provided on the valve core 620. The cross-section of the guide post 622 is adapted to the cross-section of the guide hole 614, allowing the guide post 622 to fit through the guide hole 614. This ensures that the valve core 620 can only slide axially along the valve cavity 611 and will not rotate. During the sliding process, the through hole 621 is stably aligned, misaligned, or overlaps with the inlet end 612 and the outlet end 613, and the area is adjustable.

[0053] like Figures 16 to 18 As shown, in one embodiment, a sealing ring 640 is fitted on the valve core 620, and the sealing ring 640 is in close contact with the inner wall of the valve cavity 611.

[0054] It should be noted that the valve core 620 slides reciprocally within the valve cavity 611. To eliminate the gap between the valve core 620 and the inner wall of the valve cavity 611, a sealing ring 640 is fitted onto the valve core 620. The sealing ring 640 eliminates the gap between the valve core 620 and the valve cavity 611, ensuring the sealing between the through hole 621 and the inlet end 612 and the outlet end 613. In one embodiment, two sealing rings 640 are provided, and the two sealing rings 640 are located at both ends of the through hole 621 along the axial direction of the valve core 620, thus ensuring the sealing between the through hole 621 and the inlet end 612 and the outlet end 613.

[0055] like Figures 16 to 18 As shown, in one embodiment, a sealing block 650 is provided on the valve core 620 along the radial direction, and the sealing block 650 is used to seal the water inlet end 612.

[0056] It should be noted that when the valve core 620 is adjusted to completely shut off the water flow, that is, to ensure that the inlet end 612 is completely blocked, a sealing block 650 is installed radially on the valve core 620. The sealing block 650 is also made of silicone. In this way, the inlet end 612 is completely blocked by the sealing block 650.

[0057] like Figure 1 , Figure 14 , Figure 16 , Figure 19 , Figure 20 As shown, in one embodiment, a locking button 710 is rotatably provided on one end of the shower head body 100 near the handle portion 500. The locking button 710 is also screwed to the handle portion 500. A retaining block 720 is rotatably provided inside the shower head body 100. A plurality of first retaining teeth 721 are circumferentially provided on the retaining block 720. A plurality of second retaining teeth 520 are circumferentially provided on the handle portion 500. The locking button 710 is used to rotate under force to drive each of the first retaining teeth 721 on the retaining block 720 to engage or disengage with each of the second retaining teeth 520.

[0058] It should be noted that, in order to facilitate the screwing of the locking button 710 and the handle portion 500, in one embodiment, a stud 530 is provided on the handle portion 500, and the stud 530 is located on the side of the handle portion 500 away from the knob 630. Thus, the locking button 710 and the stud 530 are screwed and fixed, and the locking button 710 and the knob 630 are respectively located on opposite sides of the main housing 110. Further, a plurality of second locking teeth 520 are arranged circumferentially around the stud 530 on the handle portion 500. Further, the locking block 720 slides relative to the main housing 110; specifically, the locking block 720 slides along the axial direction of the stud 530, and the stud 530 passes through the locking block 720. Further, a first locking tooth 721 is also provided on the side of the locking block 720 near the second locking teeth 520. Thus, when the locking button 710 is subjected to torque, it causes the locking block 720 to slide, causing the first locking tooth 721 on the locking block 720 to engage and fix with the second locking tooth 520 on the handle part 500. When it is necessary to adjust the angle between the main housing 110 and the handle part 500, the locking button 710 is released, causing the first locking tooth 721 to disengage from the second locking tooth 520. At this time, the main housing 110 and the handle part 500 can rotate to adjust the angle. After the angle adjustment is complete, the locking button 710 is locked in place, causing the first locking tooth 721 to come close together to lock the second locking tooth 520. At this time, the structure between the main housing 110 and the handle part 500 is locked and fixed. Then, by rotating the knob 630, the size of the water flow from the outlet hole 121 can be adjusted.

[0059] In one embodiment, a holding spring (not shown in the figure) is also provided between the locking button 710 and the clamping block 720. The holding spring is used to push the clamping block 720 so that the first clamping tooth 721 tends to approach and engage with the second clamping tooth 520.

[0060] It should be noted that the retaining spring pushes the locking block 720, ensuring that the locking block 720 always tends to cause the first locking tooth 721 to abut against the second locking tooth 520. Thus, when the locking button 710 is released, the first locking tooth 721 remains in contact with the second locking tooth 520. Therefore, a force must be applied between the main housing 110 and the handle 500 to overcome the elastic force of the retaining spring for adjustment to be achieved. During adjustment, the first locking tooth 721 and the second locking tooth 520 will slide and misalign, providing the user with feedback through friction sounds and vibrations, thus facilitating adjustment. Once the position between the main housing 110 and the handle 500 is determined, the locking button 710 is tightened again to ensure that the first locking tooth 721 and the second locking tooth 520 are securely locked.

[0061] like Figure 2As shown, in one embodiment, a circuit board 810 and a battery 820 are provided inside the handle portion 500. The battery 820, the motor 410, and the pump body 200 are all electrically connected to the circuit board 810. A plurality of buttons 811 are provided on the circuit board 810. The buttons 811 pass through the outer side wall of the handle portion 500 to extend to the outside.

[0062] It should be noted that, in this way, the motor 820 supplies power to the circuit board 810, the motor 410, and the pump body 200. By pressing the button 811, the start and stop of the motor 410 and the pump body 200 are controlled. In one embodiment, the outer wall of the handle portion 500 is covered with a waterproof adhesive layer, which covers each button 811. In this way, the waterproof adhesive layer isolates and waterproofs the inside of the handle portion 500. For example, the waterproof adhesive layer is made of one of silicone, polyurethane, or epoxy resin.

[0063] like Figure 1 , Figure 2 As shown, in one embodiment, the handle portion 500 includes a handle housing 501 and a cover plate 502. The handle housing 501 is hinged to the main housing 110. The circuit board 810, battery 820, and valve body 610 are all located inside the handle housing 501, and the cover plate 502 is fastened to the handle housing 501. Thus, the cover plate 502 is detachable from the handle housing 501, facilitating the replacement of the battery 820. In one embodiment, the wiring connection points between the battery 820 and the circuit board 810 are waterproofed and sealed with potting compound.

[0064] like Figure 1 , Figure 21 The figures shown illustrate two different embodiments of the electric shower head 10 of this application, wherein... Figure 1 An embodiment in which multiple protrusions 330 are provided in the outer brush head 300b. Figure 21 The illustration shows an embodiment in which a single protrusion 330 is provided in the outer brush head 300b. Further, as... Figure 22 As shown, this is the back structure of the electric shower head 10 of this application. By opening the screw cap 170 that extends from the back side, the liquid storage chamber 161 can be quickly opened, thereby adding cleaning liquids such as shower gel into the liquid storage chamber 161.
