DETAILED DESCRIPTION

[0021] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. EMBODIMENT

[0022] In combination with Figures 1 to 17 The present embodiment provides a water-lifting shower rod, which comprises a fixed rod 1 and a lifting rod 2 sleeved on the fixed rod 1. The fixed rod 1 has a water outlet cavity 11, a water inlet cavity 12 and a lifting cavity 13. The water outlet cavity 11 is communicated with a water outlet flow channel, the water inlet cavity 12 is communicated with a water inlet flow channel 121, and a first switching valve 3 is arranged to selectively connect the water inlet cavity 12 with the water outlet cavity 11 or the lifting cavity 13. The lifting cavity 13 is configured to lower the water level by opening a pressure relief valve 4, and the lifting rod 2 is configured to move upward or downward along the fixed rod 1 with the change of the water level in the lifting cavity 13, so as to adjust the height of the shower rod.

[0023] It should be noted that the shower rod of the embodiment can adjust the position of the lifting rod 2 by controlling the water level in the lifting cavity 13, thereby adjusting the overall height of the shower rod. When the first switching valve 3 selects the water inlet cavity 12 and the water outlet cavity 11 to be communicated, the water flow enters the water inlet cavity 12 from the water inlet channel 121 and flows out from the water outlet channel communicated with the water outlet cavity 11. When the first switching valve 3 selects the water inlet cavity 12 and the lifting cavity 13 to be communicated, the water flow enters the water inlet cavity 12 from the water inlet channel 121 and flows to the lifting cavity 13, so that the water level in the lifting cavity 13 rises, and the lifting rod 2 moves upward along the fixed rod 1 to adjust the height of the shower rod. When the pressure relief valve 4 is opened, the water level in the lifting cavity 13 decreases, and at this time the lifting rod 2 moves downward along the fixed rod 1 under the action of its own gravity to adjust the height of the shower rod. The first switching valve 3 of the embodiment can realize the switching of water outlet and shower rod height adjustment, which is convenient to operate and convenient for different users to use, and the structure is simple, and the automatic lifting of the shower rod can be realized without setting electronic components, and the advantages compared with the prior art are obvious.

[0024] In a preferred embodiment, the lifting cavity 13 is provided with a moving pipe 131, which is vertically arranged along the lifting cavity 13 and connected with the lifting rod 2. Specifically, one end of the moving pipe 131 is closed and arranged towards the water inlet end of the lifting cavity 13, and the other end is connected with the lifting rod 2 to drive the lifting rod 2 to move up and down with the water level. Further, the pressure relief valve 4 is arranged in the pressure relief cavity 14, and the pressure relief cavity 14 is provided with a water outlet channel 141. The lifting cavity 13 is communicated with the pressure relief cavity 14 through a water inlet channel 132, and the water passage area of the water inlet channel 132 and the water passage area of the water outlet channel 141 are both smaller than the cross-sectional area of the lifting cavity 13, so as to reduce the influence of water inlet pressure on the water level rising speed, and also to avoid the water level from falling too fast, thereby ensuring that the user can accurately adjust to the required position.

[0025] Preferably, the hole diameters of the water inlet channel 132 and the water outlet channel 141 are both not greater than 1 mm, and the diameter of the lifting cavity 13 is not less than 20 mm. Figure 16, the flow rate of the water flow is greatly affected by the water flow pressure, and therefore, in this embodiment, the hole diameter of the water inlet channel 132 is set to be much smaller than the diameter of the lifting cavity 13. According to P / kinetic=1 / 2pV2 and Q=S*V, the water source pressure rises (without considering the water flow loss) in the range of the normal use pressure of 0.1MPA to 0.55MPA required by the standard (national standard GB 18145-2014 and GB 23447), the flow rate (Q=water area S*flow rate V) is in the square root relationship with the pressure, and the ratio of the maximum flow rate to the minimum flow rate is only 2.3 times, but the filling area difference is huge. Therefore, the water inlet channel 132 of this embodiment is set to be less than 1mm in diameter, and the lifting cavity 13 is set to be greater than 20mm in diameter considering the required support weight of the product, and the area (πR2) difference between the two is at least 400 times, so as to ensure the water area difference between the water inlet and outlet channels and the lifting cavity 13, thereby reducing the influence of the water flow pressure on the water level rising speed in the lifting cavity 13, so that the user cannot feel the obvious difference in the rising speed of the lifting rod 2 between the minimum pressure and the maximum pressure of the water flow, so as to make the rising or falling speed of the lifting rod 2 tend to be constant, and further ensure the accuracy of the adjustment position. Among them, the diameter of the lifting cavity 13 can be set by using the relationship F=P*S, so as to ensure that the friction and the weight of the lifting component such as the lifting rod 2 can be overcome under the standard minimum pressure of 0.1MPA, and the effect of driving the lifting component to move upward when the water level rises can be achieved.

[0026] On the basis of the above embodiment, the water outlet end of the water outlet cavity 11 is provided with at least two water outlet flow channels, and the second switching valve 5 is arranged in the water outlet cavity 11 to selectively connect the water inlet cavity 12 with one of the water outlet flow channels. The second switching valve 5 is used to select the water outlet flow channel, so as to switch the water outlet flow channel to make the shower rod function rich, not only can automatically rise and fall, but also can divide water, and at the same time can reduce the structure design of the faucet.

[0027] Preferably, the first handle 31 for controlling the first switching valve 3, the second handle 51 for controlling the second switching valve 5, and the pressure relief handle 41 for controlling the pressure relief valve 4 are arranged vertically on the same side of the fixed rod 1, so as to make the structure more compact, and each handle is a button, which is pressed to drive the corresponding valve body to work, and the appearance is beautiful and easy to operate.

[0028] On the basis of the above-mentioned embodiments, in an optional embodiment of the present application, the first switch valve 3 comprises a first valve rod 32, a first elastic member 33 and a first base 34, the first valve rod 32 is provided with a first sealing part 321, the first elastic member 33 is arranged between the first valve rod 32 and the first base 34, and the first base 34 is used to be connected with the water inlet cavity 12; the second switch valve 5 comprises a second valve rod 52, a second elastic member 53 and a second base 54, the second valve rod 52 is provided with a second sealing part 521, the second elastic member 53 is arranged between the second valve rod 52 and the second base 54, and the second base 54 is used to be connected with the fixed rod 1, wherein the maximum cross-sectional dimension of the end of the first valve rod 32 away from the first elastic member 33 is the same as the maximum cross-sectional dimension of the first sealing part 321, and the maximum cross-sectional dimension of the end of the second valve rod 52 away from the second elastic member 53 is smaller than the maximum cross-sectional dimension of the second sealing part 521. The pressure relief valve 4 comprises a pressure relief rod 42 and a pressure relief elastic member 43, and each elastic member is preferably a spring. The working principle of the present embodiment is as follows: (1) With reference to Figure 5 , the initial state, no action is taken on the product, the water inlet cavity 12 is communicated with the water outlet cavity 11, the second elastic member 53 overcomes the friction force of the sealing ring on the second sealing part 521, so that the second sealing part 521 remains in the current position, at this time the water inlet cavity 12 is communicated with the shower water outlet flow channel 153; (2) With reference to Figure 6 , press the second handle 51 to drive the second sealing part 521 to move in the direction close to the second base 54 against the friction force and the elastic force of the second elastic member 53, at this time the water inlet cavity 12 is communicated with the top spray water outlet flow channel 151. Since the force bearing area of the second sealing part 521 is larger than the force bearing area of the end away from the second elastic member 53, that is, there is an area difference, under the action of water force Fwater=Sdiff*Pstatic, at this time the friction force+Fwater is greater than the elastic force of the second elastic member 53, after releasing the second handle 51, the second valve rod 52 can remain in the position to make the top spray water outlet flow channel 151 continuously outlet water.

[0029] (3) With reference to Figure 7 and Figure 8 , press the first handle 31 to drive the first valve rod 32 to overcome the elastic force of the first elastic member 33 and the friction force of the sealing ring, at this time the water inlet cavity 12 is switched to be communicated with the lifting cavity 13, the water flow from the water inlet cavity 12 flows into the pressure relief cavity 14 and then into the lifting cavity 13, at this time the water outlet cavity 11 is cut off from the water inlet cavity 12, and each water outlet flow channel is without water flow. Since the force bearing area of the first sealing part 321 is equal to the force bearing area of the end away from the first elastic member 33, after the lifting rod 2 moves to the required position, the first handle 31 is released, and the first valve rod 32 returns to the initial state.

[0030] (4) With reference to Figure 9When the user presses the first handle 31, the water in the water outlet cavity 11 is discharged through the water outlet flow path 121, and the water level in the lifting cavity 13 rises; when the user presses the pressure relief handle 41, the water in the pressure relief cavity 14 is discharged, and the water level in the lifting cavity 13 falls; when the lifting rod 2 is lowered to the desired position, the pressure relief handle 41 is released, and the water level in the lifting cavity 13 is maintained at the current state, and the lifting rod 2 stays at the adjusted position.

[0031] In summary, pressing the first handle 31 can make the lifting rod 2 rise, pressing the pressure relief handle 41 can make the lifting rod 2 fall, and when the handle is released, the corresponding valve body automatically resets to enable the lifting rod 2 to move and stop immediately, making adjustment convenient. At the same time, the use of the force area difference enables the second valve rod 52 to remain at the switched position, and the first valve rod and the pressure relief valve rod can automatically reset after being released, thereby simplifying the structure. It is easy to understand that when the water outlet cavity 11 is switched to be in communication with the top spray water outlet flow path 151, and needs to be switched to the shower water outlet flow path 153, the first handle 31 can be pressed to temporarily stop the water flow in the water outlet cavity 11, or the water inlet flow path 12 can be closed to make the second valve rod 32 not have a water pressure difference, and under the action of the second elastic member 53, the second valve rod 52 can return to the initial state. At the same time, the default handheld shower outlet is used to prevent the top spray water from causing mis-spraying.

[0032] On the basis of the above-mentioned embodiments, in an optional embodiment of the present application, the fixed rod 1 is provided with a water inlet member 15, the water outlet cavity 11, the water inlet cavity 12, and the water inlet end of the lifting cavity 13 are formed on the water inlet member 15, the top of the water inlet member 15 is provided with a top spray water outlet flow path 151 connected with a top spray water inlet pipe 16 and a liquid pipe water inlet part 152 connected with a liquid pipe 17, the bottom of the water inlet member 15 is provided with a shower water outlet flow path 153 connected with a shower water inlet pipe and a water inlet flow path 121 connected with a faucet water outlet pipe, the liquid pipe 17 and the liquid pipe water inlet part 152 constitute the lifting cavity 13, and the top spray water outlet flow path 151, the shower water outlet flow path 153, and the water outlet end of the water outlet cavity 11 are in communication. The lifting rod 2 is provided with a top spray water outlet pipe 21 connected with the top spray, and the top spray water outlet pipe 21 is connected with the top spray water inlet pipe 16. In one step, the water inlet member 15 is integrally formed, the top spray water inlet pipe 16 and the liquid pipe 17 are arranged in parallel, and the shower water outlet flow path 153 and the water inlet flow path 121 are arranged in parallel. The space occupation of each water path can be reduced, and the size of the shower rod can be ensured. The water inlet member 15 can be integrally formed by casting to simplify the parts, reduce assembly, and save costs. At the same time, the space occupation of each water path can be reduced, and the size of the shower rod can be ensured.

[0033] When installing the shower rod, first fix the upper wall seat 61 and the lower wall seat 62 on the wall, and then insert the upper mounting hole 18 and the lower mounting hole of the back of the fixed rod 1 into the two wall seats in position, wherein the upper mounting hole 18 is set to be small at the upper end and large at the lower end, the upper wall seat 61 is inserted from the large-diameter end and then slides into the small-diameter end under the action of gravity, so that the fixed rod 1 is limited in front and back. Then lock the screw 63 into the screw hole 19 at the bottom of the shower rod to abut against the side surface of the lower wall seat 62, so as to ensure that the shower rod is installed firmly.
