[0022] The embodiment of the present invention provides a height-adjustable bath shower head 10, please refer to Figure 1 , which includes a shower head bracket 11, a water inlet pipe section 12, a first shower head 13 and a second shower head 14.

[0023] Please refer to Figure 1-Figure 3 The shower bracket 11 includes a first bracket 111, a second bracket 112 and a driving assembly. The first bracket 111 is located above the second bracket 112, and a first liquid flow channel 1111 is provided inside the first bracket 111, and a second liquid flow channel 1121 is provided inside the second bracket 112. The first liquid flow channel 1111 is connected to the second liquid flow channel 1121, and a water outlet 1122 is provided at the lower end of the second bracket 112.

[0024] The water inlet pipe section 12 includes a hot water pipe section 121 and a cold water pipe section 122, which are respectively arranged on both sides of the second bracket 112 and are both connected to the second liquid flow channel 1121. A hot and cold water regulating valve 123 is installed at the connection between the hot water pipe section 121, the cold water pipe section 122 and the second bracket 112. The hot water in the hot water pipe section 121 and the cold water in the cold water pipe section 122 can enter the second liquid flow channel 1121 after mixing. The amount of hot water and cold water entering the second liquid flow channel 1121 can be adjusted by the hot and cold water regulating valve 123, so that the temperature of the water sprayed by the shower head can be adjusted.

[0025] The first shower head 13 is arranged at the top of the first bracket 111, and the first liquid flow channel 1111 is connected to the first shower head 13 so as to supply water to the first shower head 13. The second shower head 14 is connected to the second liquid flow channel 1121 through the connecting pipe 15, and the connecting pipe 15 includes a hard pipe section 151 and a soft pipe section 152, the first end of the hard pipe section 151 is connected to the second liquid flow channel 1121, and the second end of the hard pipe section 151 is connected to the soft pipe section 152; the first bracket 111 is equipped with a first mounting seat 16, and the first mounting seat 16 is provided with a mounting slot 161, and the second shower head 14 can be fixed to the mounting slot 161. Among them, the provision of the soft pipe section 152 makes it more convenient to use the second shower head 14 when it is removed from the first mounting seat 16. Exemplarily, the first mounting seat 16 includes a first mounting portion and a second mounting portion, the first mounting portion is connected to the first bracket 111 ; the mounting slot 161 is provided on the second mounting portion, and the second mounting portion can rotate relative to the first mounting portion, thereby adjusting the swing angle of the second shower 14 .

[0026] A water divider 171 is installed at the connection between the hard pipe section 151 and the second bracket 112, and the water divider 171 is used to adjust the water to be discharged from the first shower head 13, the second shower head 14 or the water outlet 1122. Among them, the water divider 171 can adopt the water divider 171 commonly used in existing shower heads, and the water divider 171 can control the water to be discharged from any one of the first shower head 13, the second shower head 14 and the water outlet 1122. Since water can only be discharged from one of them, when the water pressure is large, the amount of water discharged from the first shower head 13 or the second shower head 14 is large, which will cause the impact of the sprayed water on the body to be too large and cause discomfort. In this embodiment, the hard pipe section 151 includes a first hard pipe 1511 arranged vertically, and one end of the first hard pipe 1511 is connected to the second liquid flow channel 1121 through a branch pipe 153, and the branch pipe 153 is installed with a water volume regulating valve 1513 to adjust the flow rate of water passing through. The water can be diverted by the water volume regulating valve 1513. For example, when the water volume controlled by the water diverter 171 is large when the water is discharged from the first shower head 13, a part of the water in the second liquid flow channel 1121 can be diverted to the first hard pipe 1511 by the water volume regulating valve 1513, so that the water volume discharged from the first shower head 13 is reduced. When the water pressure diverted to the first hard pipe 1511 reaches a certain level, the water is discharged from the second shower head 14, and the first shower head 13 and the second shower head 14 can spray water at the same time. When the water volume controlled by the water diverter 171 is large when the water is discharged from the second shower head 14, a part of the water in the first hard pipe 1511 can be diverted to the second liquid flow channel 1121 by the water volume regulating valve 1513, so that the water volume discharged from the second shower head 14 is reduced. When the water pressure diverted to the second liquid flow channel 1121 reaches a certain level, the water is discharged from the first shower head 13, and the first shower head 13 and the second shower head 14 can spray water at the same time. The water volume regulating valve 1513 can be used to divert water, thereby preventing excessive water pressure from causing discomfort to the body.

[0027] The hard tube section 151 further includes a second hard tube 1512, one end of the second hard tube 1512 is connected to the other end of the first hard tube 1511 through an arc-shaped hard tube 1514, and the other end of the second hard tube 1512 is connected to the second liquid flow channel 1121. The arc-shaped hard tube 1514 is safer, so that the user is not easily pricked by sharp corners when taking a shower.

[0028] In addition, the shower head is also provided with a controller, and the first shower head 13 is equipped with a sensor 131, which is used to measure the distance between the first shower head 13 and the top of the user's head. The controller is connected to the driving component in communication, and controls the driving component to operate according to the distance information measured by the sensor 131. Exemplarily, the top of the first shower head 13 is connected with a mounting plate 132, and the mounting plate 132 is in an inverted L shape, which includes a top plate 1321 and a side plate 1322. The two ends of the side plate 1322 are respectively connected to the top of the first shower head 13 and the top plate 1321, and the edge of the top plate 1321 extends out of the edge of the first shower head 13. The sensor 131 is installed on the top plate 1321, so that the sensor 131 is not easily splashed with water.

[0029] In the height-adjustable bath shower head 10 of the present invention, the first shower head 13 is arranged at the top of the first bracket 111, and the first shower head 13 is installed with a sensor 131. When the user stands under the first shower head 13, the sensor 131 can measure the distance between the first shower head 13 and the top of the user's head, thereby transmitting the measured distance information to the controller, and the controller receives the distance information and controls the operation of the driving component according to the distance information. The driving component can drive the first bracket 111 to slide along the height direction of the second bracket 112. The first shower head 13 is arranged at the top of the first bracket 111, and the second shower head 14 is fixed to the first bracket 111 through the first mounting seat 16. The height of the first shower head 13 and the second shower head 14 can be adjusted at the same time, thereby achieving the effect of automatically adjusting the height of the shower head according to the height of the user, which is more convenient to use.

[0030] In some embodiments, one end of the first bracket 111 is disposed in the second bracket 112, a gap is provided between the outer wall of the first bracket 111 and the inner wall of the second bracket 112 to form a receiving cavity 114, a limiting groove 1123 is provided on the inner wall of the second bracket 112 along the height direction, a limiting protrusion 1112 and a barrier 115 are provided on the outer wall of the first bracket 111, the limiting protrusion 1112 is slidably connected to the limiting groove 1123, and the barrier 115 is slidably sealed and connected to the inner wall of the second bracket 112. In the height direction of the second bracket 112, the limiting protrusion 1112 is provided below the barrier 115. Furthermore, when the limiting protrusion 1112 moves to the lower dead point of the limiting groove 1123, the barrier 115 is located above the upper dead point of the limiting groove 1123, and when the limiting protrusion 1112 moves to the upper dead point of the limiting groove 1123, the barrier 115 is located below the top of the second bracket 112. The driving assembly includes an electric push rod 113, which is mounted on the second bracket 112, and the telescopic end of the electric push rod 113 is connected to the outer wall of the first bracket 111 through a connecting rod 1131. The controller is connected to the electric push rod 113 and the sensor 131 in communication, and the controller can receive the distance information measured by the sensor 131 and control the movement of the electric push rod 113 according to the distance information.

[0031] When the controller controls the electric push rod 113 to move, under the cooperation of the limiting protrusion 1112 of the first bracket 111 and the limiting groove 1123 of the second bracket 112, the electric push rod 113 drives the first bracket 111 to slide along the height direction of the second bracket 112. During the sliding process, the barrier 115 also moves accordingly, thereby preventing water from overflowing through the accommodating cavity 114. Exemplarily, the limiting protrusion 1112 includes a connecting portion 1112a and a matching portion 1112b for matching the limiting groove 1123, and the transverse cross-section of the matching portion 1112b is an arc surface, so that the first bracket 111 is smoother during the movement. Optionally, the barrier 115 includes a baffle plate 1151 and a sealing ring 1152 connected to the outer wall of the baffle plate 1151, and the sealing ring 1152 is slidably sealed and connected to the inner wall of the second bracket 112, and the sealing ring 1152 can effectively prevent water from overflowing.

[0032] Furthermore, the shower head also includes a waterproof part 18, which includes a first waterproof cover 181 and a second waterproof cover 182 connected to each other. The first waterproof cover 181 is sleeved outside the connecting rod 1131, and the second waterproof cover 182 is sleeved on the electric push rod 113. One end of the second waterproof cover 182 connected to the first waterproof cover 181 is a corrugated tube. The electric push rod 113 is not easily sticky by water due to the effects of the first waterproof cover 181 and the second waterproof cover 182, and has a longer service life. Since one end of the second waterproof cover 182 connected to the first waterproof cover 181 is a corrugated tube, when the telescopic end of the electric push rod 113 is telescoped, the second waterproof cover 182 can also telescope accordingly, and the electric push rod 113 can be protected all the time, and the waterproof effect is better.

[0033] Exemplarily, the electric push rod 113 is installed in the accommodating cavity 114, and the lower end of the second waterproof cover 182 is sleeved on the outer wall of the second bracket 112 and contacts the outer wall of the second bracket 112, so that water is less likely to enter from between the second waterproof cover 182 and the outer wall of the second bracket 112 to damage the electric push rod 113. In addition, along the radial direction of the second bracket 112, the first shower head 13 and the electric push rod 113 are arranged on two opposite sides of the second bracket 112, and the water sprayed by the first shower head 13 is less likely to enter the electric push rod 113.

[0034] In summary, in the height-adjustable bath shower head 10 of the present invention, the first shower head 13 is arranged at the top of the first bracket 111, and the first shower head 13 is installed with a sensor 131. When the user stands under the first shower head 13, the sensor 131 can measure the distance between the first shower head 13 and the top of the user's head, thereby transmitting the measured distance information to the controller, and the controller receives the distance information and controls the operation of the driving component according to the distance information. The driving component can drive the first bracket 111 to slide along the height direction of the second bracket 112. The first shower head 13 is arranged at the top of the first bracket 111, and the second shower head 14 is fixed to the first bracket 111 through the first mounting seat 16. The height of the first shower head 13 and the second shower head 14 can be adjusted at the same time, thereby achieving the effect of automatically adjusting the height of the shower head according to the height of the user, which is more convenient to use.

[0035] In addition, the second shower head 14 is connected to the second liquid flow channel 1121 through the connecting pipe 15. The connecting pipe 15 includes a hard pipe section 151 and a soft pipe section 152. The setting of the soft pipe section 152 makes it more convenient to use the second shower head 14 when it is removed from the first mounting seat 16. The hard pipe section 151 includes a first hard pipe 1511 arranged vertically. One end of the first hard pipe 1511 is connected to the second liquid flow channel 1121 through a branch pipe. The branch pipe is equipped with a water flow regulating valve 1513 to adjust the flow rate of water. When the water pressure is high when using the first shower head 13 or the second shower head 14, the water flow regulating valve 1513 can achieve the effect of diverting water to avoid excessive water pressure from causing discomfort to the body.
