The invention provides bathtub water supply equipment and a bathtub faucet thereof.

Referring to fig. 1 and 2, a bathtub water supply apparatus 10 according to a preferred embodiment of the present invention includes a shower head 200 and a bathtub tap 100.

The shower head 200 plays a role of spraying. The water flowing out of the shower head 200 has a large spray area.

The bath faucet 100 has an outlet pipe 136. The water flowing out of the outlet pipe 136 has a large amount of water. The bathtub water supplying apparatus 10 may control the water of the bathtub water supplying apparatus 10 to flow out of the water outlet pipe 136 or the shower head 200 according to the user's demand. For example, when rapid discharge is desired, the tub faucet 100 may control the flow of water from the outlet pipe 136; when it is desired to increase the spray area and angle of the water, the tub faucet 100 may control the flow of water out of the shower head 200.

Referring to fig. 3, the bathtub faucet 100 according to the preferred embodiment of the present invention includes a body 110, a fixing base 120, and a water diversion valve 130.

The body 110 is a hollow structure and has a receiving cavity 111. The body 110 is provided with a first drain port 112 and a second drain port 113 communicated with the accommodating cavity 111. Specifically, the body 110 is made of plastic steel, alloy or other metal having relatively high mechanical strength, so as to prevent the bathtub faucet 100 from cracking due to long-term use, and thus, water leaks from the cracks of the body 110. In particular in the bathtub water supply apparatus 10, the first drain opening 112 is provided at one end of the outlet pipe 136. The shower head 200 communicates with the second drain 113.

The fixing base 120 is disposed at one end of the body 110 and has a fixing slot 121. The sidewall of the fixing base 120 is provided with a mounting hole 122 communicating the fixing slot 121 and the accommodating cavity 111. The fixing base 120 is used for fixing the shower head 200. In the tub water supply apparatus 10, the shower head 200 may be inserted into the fixing slot 121 to receive the shower head 200 when the shower head 200 is not in use. Specifically, a plurality of slots are disposed on an end surface of the body 110 opposite to the fixing base 120, and a fixture block is disposed on a surface of the fixing base 120 facing away from the fixing slot 121, and is clamped in the slots to detachably fix the fixing base 120. Therefore, when the fixing base 120 is damaged, the fixing base 120 can be detached and the fixing base 120 can be replaced.

The shunt valve 130 is accommodated in the accommodating cavity 111. The shunt valve 130 is used to switch the water path between the tub faucet 100 and the shower head 200. Shunt valve 130 includes a valve seat 131 and a switching assembly 132.

The valve seat 131 has a hollow structure and has a receiving chamber 1311. The side wall of the valve seat 131 is opened with a first water outlet 1312 communicating with the first drain port 112, a second water outlet 1313 communicating with the second drain port 113, and a through hole 1314 aligned with the mounting hole 122. The end of the water outlet pipe 136 remote from the first drain opening 112 is communicated with the first water outlet 1312.

Specifically, the valve seat 131 may be a rectangular parallelepiped, a cylinder, a polyhedron, or other shape, and in this embodiment, the valve seat 131 is a rectangular parallelepiped. The cuboid is the common shape of valve seat 131, and simple manufacture is convenient for reduce the manufacturing cost of valve seat 131. Moreover, the surfaces of the rectangular parallelepiped valve seat 131 are six differently oriented flat surfaces. Therefore, the first water outlet 1312, the second water outlet 1313 and the through hole 1314 can be disposed on different planes without interfering with each other. The valve seat 131 is arranged to be a cuboid, so that the uniform arrangement of a plurality of outlets on the bathtub faucet 100 is facilitated, and parts arranged on the valve seat 131 are not affected by each other.

Specifically, the first water outlet 1312 may be disposed on one surface of the valve seat 131, the through hole 1314 is opened on a surface of the valve seat 131 opposite to the first water outlet 1312, and the second water outlet 1313 is disposed on two planar surfaces connecting the first water outlet 1312 and the through hole 1314. If the plane on which the first water outlet 1312 is disposed is referred to as a left plane, the plane on which the through hole 1314 is disposed is a right plane, and the plane on which the second water outlet 1313 is disposed is a lower plane. Of course, the left, right and lower planes are relative only, and they can be switched when the valve seat 131 is rotated. Therefore, in the present embodiment, the axial direction of the first water outlet 1312 is parallel to the axial direction of the through hole 1314, and the axial direction of the second water outlet 1313 is perpendicular to the axial direction of the first water outlet 1312.

Referring to fig. 4, the switching assembly 132 includes a switching shaft 1321 and a switching elastic member 1322. The switching shaft 1321 is slidably inserted through the through hole 1314 and the mounting hole 122. The switching shaft 1321 includes an extended state partially extended into the fixing insertion groove 121 and a retracted state retracted into the mounting hole 122. The switching elastic member 1322 is used for providing an elastic force to the switching shaft 1321, so that the switching shaft 1321 has a tendency to switch from the retracted state to the extended state.

Wherein, in the extended state, the switching shaft 1321 operates the first water outlet 1312 to be closed, and the second water outlet 1313 to be opened; in the retracted state, the switching shaft 1321 operates the first water outlet 1312 to be opened and the second water outlet 1313 to be closed.

Specifically, the shower head 200 may be communicated with the second water outlet 1313, when the shower head 200 is inserted into the fixing slot 121, the outer wall of the shower head 200 drives the switching shaft 1321 to retract to the retracted state, at this time, the switching shaft 1321 moves in a direction back to the shower head 200, the switching elastic member 1322 is gradually compressed, when the elastic force of the switching elastic member 1322 is equal to the extrusion force of the outer wall of the shower head 200, the switching shaft 1321 stops moving, the switching elastic member 1322 reaches the maximum value of the compression, at this time, the switching shaft 1321 retracts into the mounting hole 122, the first water outlet 1312 is opened, and the second water outlet 1313 is closed, so that water can be discharged from the bathtub faucet 100. When the shower head 200 is pulled out, the pressing force of the outer wall of the shower head 200 on the switching shaft 1321 disappears, and the switching shaft 1321 extends to the extended state under the action of the switching elastic member 1322. At this time, the switching shaft 1321 moves reversely, the switching shaft 1321 partially extends into the fixing slot 121, and the switching elastic member 1322 is restored to the original length and is in a natural extension state. Further, the first water outlet 1312 is closed, and the second water outlet 1313 is opened, so that water can be discharged from the shower head 200. The control of water outlet can be realized by inserting and taking out the shower head 200. Therefore, compared with the conventional method of switching the water path by manually switching the switching valve core, the bathtub water supply apparatus 10 and the bathtub faucet 100 thereof can switch the water path only by inserting and taking out the shower head 200, thereby having the characteristic of simple operation.

Specifically, in the present embodiment, the bathtub faucet 100 further includes a valve core 137, a valve core seat 143, a valve core gland 138, a handle 139, a hot water pipe 140, a cold water pipe 141, and a mixed water pipe 148. The middle portion of the body 110 is provided with an accommodating port 142 communicated with the accommodating cavity 111. The water outlet pipe 136, the valve core 137 and the valve core seat 143 are all accommodated in the accommodating cavity 111, and the valve rod 151 on the valve core 137 extends out of the accommodating port 142. The valve plug gland 138 is disposed on the valve stem 151 to fix the valve plug 137 in the body 110. The handle 139 is drivingly connected to the valve stem 151. The valve core seat 143 is provided with a cold water channel 144, a hot water channel 145 and a mixed water channel 146, the cold water pipe 141 is communicated with the cold water channel 144, the hot water pipe 140 is communicated with the hot water channel 145, and two ends of the mixed water pipe 148 are respectively communicated with the mixed water channel 146 and the accommodating cavity 1311. The valve body 137 is provided with water chambers respectively communicated with the cold water passage 144, the hot water passage 145 and the mixed water passage 146. The valve rod 151 is controlled by the handle 139 to move, so that the amount of water in the cold water channel 144 and the hot water channel 145 can be controlled, and the cold water and the hot water are mixed in the water cavity to form the temperature and the amount of water required by the user. The valve seat 131 is provided with a water inlet 152, one end of the mixed water pipe 148 far away from the valve core seat 143 is communicated with the water inlet 152, and the synthesized mixed water flows into the shunt valve 130 through the mixed water pipe 148. In addition, the hot water pipe 140 and the cold water pipe 141 may be fixed to an indoor wall by a hot water pipe nut set 149 and a cold water pipe nut set 150, respectively.

Referring to fig. 5, in the present embodiment, the water diversion valve 130 further includes a water diversion assembly 133 accommodated in the accommodating cavity 1311. The side surface of the switching shaft 1321 is an undulating surface having a wave crest 1323 and a wave trough 1324, and the water diversion assembly 133 includes a water diversion shaft 1331 and a water diversion elastic member 1332. The water diversion shaft 1331 penetrates the water diversion valve 130, one end of the water diversion elastic piece 1332 is installed on the inner wall of the water diversion valve 130, and the other end is in transmission connection with the water diversion shaft 1331. A convex part 1336 and a blocking part 1333 are respectively formed at the middle part of the water diversion shaft 1331, and the convex part 1336 is abutted with the undulating surface.

When the switching shaft 1321 is in the extended state, the protruding portion 1336 abuts against the trough 1324, the blocking portion 1333 is blocked at the first water outlet 1313, and the second water outlet 1312 is opened;

when the switching shaft 1321 is in the retracted state, the protruding portion 1336 abuts against the wave peak 1323, the blocking portion 1333 blocks the second water outlet 1312, and the first water outlet 1313 is opened.

Specifically, when the shower head 200 is inserted into the fixing slot 121, the outer wall of the shower head 200 drives the switching shaft 1321 to retract to the retracted state, and at this time, the switching shaft 1321 moves in a direction back to the shower head 200, and drives the relief surface to move in a direction from the mounting hole 122 to the through hole 1314. The undulating surface in contact with the projection 1336 gradually moves from the peak 1323 to the valley 1324. The water diversion elastic piece 1332 drives the convex portion 1336 to abut against the undulating surface, and simultaneously drives the blocking portion 1333 and the water diversion shaft 1331 to slide along the direction perpendicular to the axis of the through hole 1314, so that the blocking portion 1333 is blocked at the second water outlet 1313, and the first water outlet 1312 is opened. Water can be discharged from the tub faucet 100. In the process, the switching elastic member 1322 is transformed from the natural extension state to the compression state, and the water diversion elastic member 1332 is transformed from the compression state to the natural extension state.

When the shower head 200 is pulled out, the pressing force of the outer wall of the shower head 200 on the switching shaft 1321 disappears, and the switching shaft 1321 extends to the extended state under the action of the switching elastic member 1322. At this time, the switching shaft 1321 moves in the opposite direction, and the switching elastic member 1322 drives the switching shaft 1321 to drive the relief surface to move along the direction from the through hole 1314 to the mounting hole 122. The undulating surface in contact with the projection 1336 gradually moves from the valley 1324 to the peak 1323. The undulating surface abuts against the convex column and pushes the convex column to drive the blocking part 1333 and the water distribution shaft 1331 to slide along the direction perpendicular to the axis of the through hole 1314, the water distribution elastic part 1332 is gradually compressed, and the blocking part 1333 is blocked at the first water outlet 1312. Meanwhile, part of the switching shaft 1321 gradually protrudes out of the mounting hole 122 and into the fixing slot 121. The switching spring 1322 returns to its original length, in a natural extended state, and the water-diverting spring 1332 reaches its maximum value of compression. At this time, the first water outlet 1312 is closed, and the second water outlet 1313 is opened, so that water can be discharged from the shower head 200.

In the present embodiment, the switching shaft 1321 has a transmission end 1327 and an operation end 1328 which are oppositely arranged. The driving end 1327 is cylindrical and passes through the through hole 1314 and the mounting hole 122, the operating end 1328 is block-shaped and abuts against the switching elastic member 1322, and the diameter of the operating end 1328 is larger than the inner diameter of the through hole 1314.

The relief surface may be located at the operating end 1328. Typically, the via 1314 is a circular via 1314. The transmission end 1327 is configured to be a cylindrical structure and is disposed in the through hole 1314 in a penetrating manner, so that the friction force of the switching shaft 1321 in the sliding process can be reduced, and the operation of the switching shaft 1321 is more stable. Moreover, the engagement of the cylindrical drive end 1327 with the circular bore 1314 reduces mechanical wear between the valve seat 131 and the switching shaft 1321, thereby facilitating an extended service life of the bathtub faucet 100.

To prevent water from escaping through the gap between the bore 1314 and the drive end 1327 and affecting the operation of the tub faucet 100, an O-ring seal may also be provided in the bore 1314. The sealing ring is clamped between the driving end 1327 and the inner wall of the through hole 1314 to prevent the mixed water in the valve seat 131 from leaking from the through hole 1314.

Further, the operation end 1328 is block-shaped, and the diameter of the operation end 1328 is larger than the inner diameter of the through hole 1314, so that the switching shaft 1321 is prevented from being popped out of the valve seat 131 by a large elastic restoring force due to excessive compression of the switching elastic member 1322 in an accidental situation, thereby facilitating the normal operation of the bathtub faucet 100.

Further, in the present embodiment, the diameter of the end of the driving end 1327 is gradually reduced in the direction from the operating end 1328 to the driving end 1327.

Therefore, when the switching shaft 1321 is installed in the valve seat 131, a larger gap is formed between the end of the transmission end 1327 and the through hole 1314, so that the transmission end 1327 is easily inserted into the through hole 1314 to install the transmission end 1327. Specifically, the end of the transmission end 1327 may be truncated cone-shaped, conical or in other shapes, and in this embodiment, one side of the end of the transmission end 1327 is provided with an inclined surface. When the shower head 200 is installed in the bathtub water supply device 10, if the contact area between the transmission end 1327 and the shower head 200 is too small, the driving force of the shower head 200 generates a large pressure at the transmission end 1327, and the transmission end 1327 is unstable in operation due to uneven stress. Therefore, the transmission end 1327 is provided as an inclined surface, so that the contact area of the switching shaft 1321 and the shower head 200 can be increased while the switching shaft 1321 is simply installed, thereby facilitating the shower head 200 to apply a driving force to the switching shaft 1321, and making the switching shaft 1321 operate smoothly.

Specifically, the switching elastic member 1322 may be a spring, an elastic rubber, a high-strength rubber, or other elastic material. Specifically, in the present embodiment, the switching elastic member 1322 is a spring. A through groove 13271 is formed in an end surface of the switching shaft 1321 away from the through hole 1314, the through groove 13271 extends along an axial direction of the accommodating cavity 1311, and two ends of the spring respectively abut against an inner wall of the accommodating cavity 1311 and a bottom of the through groove 13271.

The spring is a common structure for switching the elastic piece 1322, the material is convenient to obtain, and the manufacturing cost is low. Furthermore, one end of the switching elastic piece 1322 is received in the through groove 13271, and the through groove 13271 guides the movement of the switching elastic piece 1322, so that the switching elastic piece 1322 is prevented from swinging during the movement to affect the sliding of the switching shaft 1321.

Further, in the present embodiment, the edges of the opposite sides of the through groove 13271 extend in the direction of getting closer to each other to form the stopper 1329. The surface of the limiting portion 1329 facing the through slot 13271 abuts against the switching elastic piece 1322 to limit one end of the switching elastic piece 1322 in the through slot 13271.

By providing the stopper 1329, one end of the switching elastic piece 1322 can be stably fixed to the switching shaft 1321, so that the switching elastic piece 1322 is prevented from falling off the switching shaft 1321 and failing to move the switching shaft 1321.

In other embodiments, both ends of the switching elastic member 1322 may be fixed to the inner wall of the valve seat 131 and the switching shaft 1321 by fasteners, respectively.

Specifically, the undulating surface may be a concave-convex undulating surface, or may be a surface structure having the farthest point and the closest point, which is formed by combining the circular arc surface 1325 and the switching plane 1326. Specifically, with a reference plane perpendicular to the left plane of the valve seat 131 as a standard, the farthest point is the point where the circular arc surface 1325 is farthest from the reference plane, and the closest point is the point where the circular arc surface 1325 is connected to the reference plane. Specifically, in this embodiment, the undulating surface includes an arc surface 1325 and a switching plane 1326 connected to two ends of the arc surface 1325, the wave trough 1324 is disposed at a connection position between the switching plane 1326 and the arc surface 1325, the wave peak 1323 is disposed at a farthest position of the arc surface 1325 from the switching plane 1326, and the convex portion 1336 has a cylindrical structure and slides along the undulating surface.

The convex portion 1336 has a cylindrical structure, and the relief surface is a combination of the switching planes 1326 of the circular arc surface 1325, so that the convex portion 1336 has smaller resistance in the process of sliding along the circular arc surface 1325, and the operation of the convex portion 1336 is more stable. Moreover, compared with the concave-convex wavy surface, the forming process of the wavy surface formed by the circular arc surface 1325 and the switching plane 1326 is relatively simple, and the production cost of the switching shaft 1321 is reduced conveniently.

In other embodiments, the peak 1323 and the trough 1324 may be both wave surfaces or middle points of the combination of the circular arc surface 1325 and the plane, and the combination of the peak 1323 and the trough 1324 may be any, so long as the distance from the peak 1323 to the lowest point of the undulating surface is greater than the distance from the trough 1324 to the lowest point of the undulating surface.

In this embodiment, diverter valve 130 also includes two guide strips 134. Two guide chasses 134 are arranged in parallel and spaced apart and extend in a direction perpendicular to the axis of the through-hole 1314 to form a guide channel 135. The protrusion 1336 is inserted through the guide passage 135 and is slidable along the guide passage 135.

The guide channel 135 formed by the two guide chasses 134 has a guiding effect on the sliding of the projection 1336. Therefore, by providing the guide passage 135, the sliding range of the projection 1336 can be restricted within the guide passage 135. Further, the first water outlet 1312 or the second water outlet 1313 may not be completely blocked due to the swing of the protrusion 1336 and the water diversion shaft 1331 during the movement, so that the bathtub faucet 100 may have only a single water outlet route.

In this embodiment, the water dividing elastic member 1332 is a wrap spring. A groove 13112 is formed on the inner wall of the receiving cavity 1311 at a position opposite to the water-separating elastic member 1332. One end of the water diversion elastic piece 1332 is sleeved on the water diversion shaft 1331, and the other end is accommodated in the groove 13112 and abuts against the bottom of the groove 13112.

By arranging the water diversion elastic piece 1332 as a sleeve spring, and sleeving one end of the sleeve spring on the water diversion shaft 1331 and accommodating the other end of the sleeve spring in the groove 13112, the arrangement mode of the water diversion elastic piece 1332 is simple and easy, and the installation efficiency is improved conveniently. Furthermore, the groove 13112 and the diversion shaft 1331 also have a guiding function for the spring set, so as to prevent the diversion elastic piece 1332 from swinging during the compression or recovery deformation process to influence the movement of the diversion shaft 1331. In order to achieve a better guiding effect, a through hole or a guide groove may be further formed in the inner wall of the accommodating cavity 1311 opposite to the groove 13112, and one end of the water diversion shaft 1331, which is far away from the water diversion elastic member 1332, is inserted into the guide groove or the through hole, so that the movement path of the water diversion shaft 1331 may be limited on the connection line between the through hole and the groove 13112 or the connection line between the guide groove and the groove 13112, and further, the movement of the water diversion shaft 1331 is more stable. Therefore, the blocking part 1333 may completely block the first water outlet 1312 or the second water outlet 1313 during the movement.

It should be noted that in other embodiments, the water diversion elastic member 1332 is not limited to a spring, but may be other forms of elastic member structures. Furthermore, both ends of the water diversion elastic member 1332 may be fixed to the inner wall of the valve seat 131 and the water diversion shaft 1331 by fasteners.

In the present embodiment, two blocking portions 1333 are provided at intervals in the axial direction of the diversion shaft 1331, and the two blocking portions 1333 are distributed axisymmetrically with respect to the axis of the protruding portion 1336.

The protruding portion 1336 is sandwiched between two closing portions 1333, and the two closing portions 1333 are provided symmetrically with respect to the axis of the protruding portion 1336. In addition, the diversion shaft 1331 is also disposed in axial symmetry with respect to the axis of the protrusion 1336. Therefore, in the process that the relief surface pushes the protruding portion 1336 to drive the water diversion shaft 1331 and the blocking portion 1333 to move, the two sides of the protruding portion 1336 are stressed equally, so that the relief surface stably drives the blocking portion 1333 to move, and the blocking of the first water outlet 1312 or the second water outlet 1313 is achieved. The two blocking portions 1333 may be named as a first blocking portion and a second blocking portion, the first blocking portion is blocked at the first water outlet 1312, and the second blocking portion is blocked at the second water outlet 1313, therefore, compared with the one blocking portion 1333, the two blocking portions 1333 only need to move a small displacement in the operation process, so as to close the first water outlet 1312 or the second water outlet 1313, and thus, the time for switching the water path can be effectively shortened, and the rapid replacement of the water path is convenient. Further, since a small displacement means that only a small space is required in the valve seat 131, the two blocking portions 1333 can effectively reduce the volume of the valve seat 131, which facilitates the miniaturization of the water passage switching device.

Specifically, the blocking portion 1333 includes a circular base portion 1334 having a certain thickness and a circular truncated cone structure 1335 protruding from the circular base portion 1334. When the two blocking portions 1333 are disposed on the water diversion shaft 1331, the two truncated cone structures 1335 are respectively disposed on the surfaces of the two circular base portions 1334 facing away from the convex portion 1336. Therefore, when the wrap spring is sleeved on the water diversion shaft 1331, one end of the wrap spring away from the groove 13112 can abut against the surface of the circular truncated cone structure 1335 facing away from the circular base 1334. Since the diameter of the circular truncated cone structure 1335 gradually increases along the direction from the circular truncated cone structure 1335 to the circular base 1334, the set spring can be blocked between the circular truncated cone structure 1335 and the groove 13112 by the circular truncated cone structure 1335, so that the set spring can be prevented from randomly moving along the axis of the water diversion shaft 1331 when being sleeved on the water diversion shaft 1331 to influence the effect of water path switching. In addition, the circular truncated cone structure 1335 disposed at an end away from the water diversion elastic piece 1332 can prevent the water diversion shaft 1331 from being in rigid contact with the inner wall of the valve seat 131 to damage the protruding part 1336 during the moving process, thereby facilitating the maintenance of the normal use of the bathtub faucet 100.

Further, in order to prevent the first blocking portion from being blocked at the first water outlet 1312 and prevent the second blocking portion from being blocked at the second water outlet 1313, when the mixed water flows out from the first water outlet 1312 or the gap between the second water outlet 1313 and the blocking portion 1333, both the first blocking portion and the second blocking portion may be made of a soft rubber material with a certain hardness. The first blocking portion and the second blocking portion made of the soft rubber material can deform when the first water outlet 1312 and the second water outlet 1313 are sealed, so that the first blocking portion and the second blocking portion can be better attached to the first water outlet 1312 and the second water outlet 1313, and mixed water can be prevented from flowing out of the first water outlet 1312 and the second water outlet 1313 simultaneously due to the fact that a gap exists between the blocking portion 1333134 and the first water outlet 1312 or the second water outlet 1313.

With the coordinate positions of the left and right planes of the valve seat 131 as a reference system, the left side of the circular base 1334 of the first blocking portion blocks the first water outlet 1312 and the lower side of the circular base 1334 of the second blocking portion blocks the second water outlet 1313 during the movement of the blocking portion 1333. And in order to facilitate the water diversion assembly 133 and the switching assembly 132 to be rapidly installed in the valve seat 131, the four inner walls of the valve seat 131, which are provided with the water inlet 152, the through hole 1314, the groove 13112 and the guide groove, can be installed by welding. Before welding, the water diversion assembly 133 and the switching assembly 132 are installed in the accommodating cavity 1311 of the valve seat 131, and then the four side walls are fixedly connected in a welding manner, so that the bathtub faucet 100 can be easily installed.

The water inlet 152, the first water outlet 1312 and the second water outlet 1313 are all communicated with the corresponding pipelines through water pipe joints, so that the corresponding pipelines can be fixed, and waste of water resources caused by outflow of mixed water from gaps in the flowing process can be prevented.

According to the bathtub water supply device 10 and the bathtub faucet 100 thereof, the shower head 200 can be communicated with the second water outlet 1313, when the shower head 200 is inserted into the fixing slot 121, the outer wall of the shower head 200 drives the switching shaft 1321 to retract to a retracted state, at this time, the switching shaft 1321 moves along the direction back to the shower head 200 until retracting to the mounting hole 122, the first water outlet 1312 is opened, and the second water outlet 1313 is closed, so that water can be discharged from the bathtub faucet 100. When the shower head 200 is pulled out, the switching shaft 1321 is extended to the extended state by the switching elastic member 1322. At this time, the switching shaft 1321 moves reversely, the switching shaft 1321 partially extends into the fixing slot 121, the first water outlet 1312 is closed, and the second water outlet 1313 is opened, so that water can be discharged from the shower head 200. The control of water outlet can be realized by inserting and taking out the shower head 200. Therefore, the bathtub water supplying apparatus 10 and the bathtub tap 100 thereof have a simple operation compared to the conventional method of switching the waterway by manually switching the switching valve.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
