Description

Technical Field

[0001] The invention belongs to the technical field of bathrooms and relates to a bathroom spray gun. Background Art

[0002] At present, most toilets are usually equipped with spray guns, which can be used to clean the toilet itself or the ground around the toilet, and can also be used to clean the body. In the past, the spray gun was directly connected to cold water, which would not have any effect on cleaning the toilet or the ground around the toilet, but if it was used to clean the body, it would cause discomfort due to the low temperature. Therefore, now a mixing valve with a hot and cold water mixing function is installed on the wall near the toilet, and the mixing valve is connected to the spray gun to provide mixed water for it. The user can adjust the water outlet temperature of the spray gun through the mixing valve to ensure comfort when washing the body. Among them, the mixing valve is only used to supply mixed water to the spray gun, and the opening or closing of the spray gun is achieved by its own switch, that is, the mixing valve is always open during normal use. Existing spray guns do not have a temperature display function. After turning it on, the user cannot intuitively grasp the actual water outlet temperature, and can only rely on the skin to touch the water outlet to perceive it. However, if the water outlet temperature is mistakenly set to a high level before, it is easy to burn the skin, so it is not very convenient to use.

[0003] To address this problem, there is a self-generating shower head on the market with patent application number 202223406180.2, which includes a shower body, a holding tube connected to the lower end of the shower body, a digital display panel fixedly installed on the top of the shower body, a small hydroelectric generator fixedly installed on the lower end of the shower body, the upper water outlet of the small hydroelectric generator is sealed and connected to the lower water inlet of the shower body, a wire outlet is provided at the upper end of the small hydroelectric generator near the rear side, a wire outlet is led out from the wire outlet, the wire is located between the small hydroelectric generator and the digital display panel, one end of the wire is connected to the digital display panel, and the other end of the wire is connected to the small hydroelectric generator, the digital display panel is electrically connected to the small hydroelectric generator through the wire, a nozzle is installed at the front end of the shower body, the nozzle is detachably connected to the shower body, the nozzle includes a shower outer shell, a fixed disk is provided inside the shower outer shell, an upper water outlet is provided on the upper side of the fixed disk, and a lower water outlet is provided on the lower side of the fixed disk. In addition, a switch is also provided on the shower body to realize the on-off control. When the shower is turned on, the flowing water can drive the small hydroelectric generator to generate electricity, and the electricity generated by the small hydroelectric generator can be transmitted to the digital display panel through the wire, so that the digital display panel can realize the digital display of the temperature with the help of the electricity of the small hydroelectric generator, so that the user can grasp the water temperature in real time to avoid scalding.

[0004] Combined with the drawings in the manual, it can be seen that the digital display panel, small hydroelectric generator and switch are all installed separately during assembly, and the internal space of the shower is relatively small. When installing these components, it is obvious that attention must be paid to the interference and avoidance between them, which makes assembly inconvenient. In particular, for the digital display panel and the small hydroelectric generator, because the two need to be electrically connected with wires, and the wires are to be located inside the shower, the only way is to install the small hydroelectric generator first, then pass the wires through the installation position of the digital display panel and connect them to the digital display panel, and then plug the wires back into the shower and fix the digital display panel to the installation position. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems existing in the prior art and to propose a bathroom spray gun, which solves the problem of inconvenient assembly caused by realizing water temperature display.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A bathroom spray gun comprises a shell, a digital display module and a hydraulic generator which are both arranged in the shell and electrically connected, an opening and closing piece is also arranged in the shell, and a push button is also arranged outside the shell, characterized in that a water inlet and a water flow body are arranged in the shell from back to front, the water inlet and the water flow body are plugged or clamped and fixed, and the opening and closing piece is slidably arranged between the two along the front and back, the digital display module is fixed on the side of the water flow body and the hydraulic generator is fixed in the water inlet, the opening and closing piece is cylindrical with openings at both ends, the opening and closing piece has a stepped inner hole which is larger at the front and smaller at the back, the opening and closing piece is simultaneously sleeved on the front end of the water inlet and the rear end of the water flow body, a water outlet is arranged on the side of the front end of the water inlet and a sealing ring is sleeved and fixed thereon, the sealing ring is located in front of the water outlet and abuts against the rear hole wall of the stepped inner hole to form a seal, a strip-shaped makeshift groove is arranged on the side of the shell along the front and back, and the push button passes through the makeshift groove and is fixed to the opening and closing piece.

[0008] When in use, connect the bathroom spray gun to the water pipe. When the bathroom spray gun is in the closed state, the sealing ring 1 is located in the rear part of the stepped inner hole of the opening and closing part, and the sealing ring 1 is against the rear hole wall of the stepped inner hole of the opening and closing part to form a seal. At this time, the water outlet is blocked behind the sealing ring 1, so that the water cannot flow into the water body. When it is necessary to open, the user pushes the push button backward to drive the opening and closing part to slide backward. The positions of the water inlet and the water body are fixed. As the opening and closing part slides backward, the sealing ring 1 and the water outlet will be located in the front part of the stepped inner hole. At this time, the sealing ring 1 no longer forms a sealing effect and loses the function of blocking water. In this way, the water from the water pipe can flow smoothly into the water body after flowing out of the water outlet. In the process of water flowing, it will drive the impeller in the hydroelectric generator to rotate, thereby realizing power generation to power the digital display module to display the water temperature.

[0009] The bathroom spray gun is provided with a water inlet body and a water flow body which are plugged in or clipped in and fixed in the shell, and the opening and closing member is provided with a cylindrical shape with openings at both ends, the opening and closing member has a stepped inner hole which is larger at the front and smaller at the rear, the opening and closing member is simultaneously sleeved on the front end of the water inlet body and the rear end of the water flow body, the front end side of the water inlet body is provided with a water outlet and a sealing ring 1 is sleeved and fixed, the sealing ring 1 is located in front of the water outlet and abuts against the hole wall with the smaller aperture in the stepped inner hole to form a seal, so that the water inlet body and the water flow body can be connected or cut off when the opening and closing member slides forward and backward, that is to say, the water inlet body, the opening and closing member and the water flow body form a modular component which has its own waterway inside and can realize the waterway cutting-off function (during actual assembly, the opening and closing member can be first sleeved on the outside of the front end of the water inlet body, and then the rear end of the water flow body can be inserted into the opening and closing member, and the water flow body and the water inlet body can be directly plugged in or clipped in and fixed). On the basis that the modular component has its own water channel inside, power generation can be generated by directly fixing the hydroelectric generator in the water inlet body, and the water temperature can be displayed by directly fixing the digital display module on the side of the water body. After this combination, the opening and closing parts, the hydroelectric generator and the digital display module no longer need to be separately installed and fixed in the shell and connected accordingly as before. They can be directly assembled outside the shell and then installed into the shell as a whole. Finally, the push button can be passed through the give way groove on the side of the shell to connect with the opening and closing parts. While realizing the water temperature display function, it also solves the problem of inconvenient assembly caused by this.

[0010] In the above-mentioned bathroom spray gun, the hydraulic generator is connected to a columnar male terminal through a wire, the digital display module is connected to a columnar female terminal through a wire, and the side of the opening and closing member is integrally fixed with a positioning part along its length direction. The cross-section of the positioning part is roughly horizontally U-shaped or C-shaped and the positioning part is elastic. The male terminal is connected to the female terminal and is stuck on the inner side of the positioning part.

[0011] By setting the male terminal and the female terminal, the electrical connection between the hydroelectric generator and the digital display module can be quickly achieved. The positioning part is integrally fixed on the side of the opening and closing part. The positioning part is arranged along the handle in a long strip shape. The cross section of the positioning part is roughly U-shaped or C-shaped and the positioning part is elastic. After the male terminal and the female terminal are docked, they are stuck on the inner side of the positioning part. Then, the male terminal and the female terminal after docking can be positioned so that the part formed after the male terminal and the female terminal are docked can be firmly clamped to avoid interference in the process of installing the module composed of the digital display module, the hydroelectric generator, the opening and closing part, the water body and the water inlet body into the handle. Moreover, positioning the male terminal and the female terminal after docking can also ensure that they will not shake at will and generate noise when the user holds the bathroom spray gun in use.

[0012] In other words, the opening and closing piece not only plays the role of opening and closing the bathroom spray gun, but also plays the role of positioning the male terminal and the female terminal after docking. Therefore, the opening and closing piece has two uses.

[0013] In the above-mentioned bathroom spray gun, a groove is provided on the side of the water flow body, the digital display module is positioned in the groove, a wire threading port is provided on the bottom wall of the groove, the female terminal is passed through the wire threading port, a wire outlet hole is provided on the water inlet body, and a water inlet joint is connected to the rear end internal thread of the water inlet body, the water inlet joint extends out of the outer shell and the water inlet joint positions the hydraulic generator in the water inlet body.

[0014] During installation, after the digital display module is positioned in the groove, the female terminal is passed through the threading port, the hydroelectric generator is placed in the rear end of the water inlet body, and the water inlet joint is used to position it, and the male terminal is passed through the outlet hole, and then the female terminal and the male terminal are directly connected. Through the above arrangement, the digital display module fixed on the side of the water body can be easily electrically connected or disconnected with the hydroelectric generator fixed in the water inlet body.

[0015] In the above-mentioned bathroom spray gun, the water inlet body includes a cylindrical water outlet portion arranged along the front-to-back direction and a long strip-shaped connecting piece arranged along the front-to-back direction. The water outlet and the sealing ring are both arranged on the water outlet portion. The water outlet portion is located on one side of the connecting piece and there is a clearance between the two along the radial direction of the water outlet portion for the opening and closing member to be sleeved outside the water outlet portion. The front end of the connecting piece is plugged or clamped and fixed to the water flow body.

[0016] During assembly, the opening and closing piece is first sleeved on the outside of the water outlet part 1, and then the rear end of the water body is directly inserted into the opening and closing piece and the front end of the connecting piece 1 is plugged or clamped with the water body so that the water body, the opening and closing piece and the water inlet can be connected as a whole. Among them, the connecting piece 1 is long and strip-shaped along the front and rear direction, and such a shape allows the water inlet to be plugged or clamped with the water body after the opening and closing piece is sleeved.

[0017] In the above-mentioned bathroom spray gun, a mating portion is protruding from the side of the opening and closing member, the push button is fixed to the mating portion, a guide strip is provided on the side of the connecting piece along its length direction, a guide groove is provided on the side of the opening and closing member, and the guide strip is located in the guide groove.

[0018] The push button is connected to the mating part protruding from the side of the opening and closing member, so there are requirements for the circumferential position. By setting a guide strip 1 on the side of the connecting piece 1 along its length direction and a corresponding guide groove 1 on the side of the opening and closing member, when the opening and closing member is sleeved outside the water outlet 1 of the water inlet body, the guide strip 1 is directly inserted into the guide groove 1, which can ensure that the opening and closing member can slide in the front and back direction to open or close the bathroom spray gun, and the opening and closing member and the connecting piece 1 can be fixed in the circumferential direction to limit the angle of the opening and closing member in the circumferential direction to ensure the rapid connection between the opening and closing member and the push button.

[0019] Through such an arrangement, the connecting piece has two functions. One function is to fix the water inlet body and the water flow body so that the water inlet body, the water flow body and the opening and closing member are connected together to form an assembly. The other function is to circumferentially limit the mating part on the side of the opening and closing member to ensure the quick connection between the opening and closing member and the push button.

[0020] In the above-mentioned bathroom spray gun, as another technical solution, the water flow body includes a cylindrical water inlet part two arranged along the front-to-back direction and a long strip-shaped connecting piece two arranged along the front-to-back direction. The water inlet part two is located on one side of the connecting piece two and there is a clearance between the two along the radial direction of the water inlet part two for the opening and closing part to be sleeved on the outside of the water inlet part two. The rear end of the connecting piece two is plugged or clamped and fixed to the water inlet body.

[0021] During assembly, the opening and closing piece is first sleeved on the outside of the water inlet part 2, and then the rear front end of the water inlet body is directly inserted into the opening and closing piece and fixed with the water inlet body through the rear end of the connecting piece 2, so that the water body, the opening and closing piece and the water inlet body can be connected as a whole. Among them, the connecting piece 2 is long and narrow along the front and rear direction, and such a shape allows the water body to be inserted or fixed with the water inlet body after the opening and closing piece is sleeved.

[0022] In the above-mentioned bathroom spray gun, a mating portion is protruding from the side of the opening and closing member, the push button is fixed to the mating portion, a guide strip 2 is provided on the side of the connecting piece 2 along its length direction, a guide groove 2 is provided on the side of the opening and closing member, and the guide strip 2 is located in the guide groove 2.

[0023] The push button is connected to the mating part protruding from the side of the opening and closing member, so there are requirements for the circumferential position. By setting the second guide strip on the side of the second connecting piece along its length direction and the second guide groove on the side of the opening and closing member, when the opening and closing member is sleeved outside the second water inlet of the water body, the second guide strip is directly inserted into the second guide groove. This can ensure that the opening and closing member can slide in the front and back direction to open or close the bathroom spray gun, and the opening and closing member and the second connecting piece can be fixed circumferentially to limit the angle of the opening and closing member along the circumferential direction to ensure the quick connection between the opening and closing member and the push button.

[0024] Through such an arrangement, the connecting piece 2 has two functions. One function is to fix the water inlet body and the water flow body so that the water inlet body, the water flow body and the opening and closing member are connected together to form an assembly. The other function is to circumferentially limit the mating part on the side of the opening and closing member to ensure the quick connection between the opening and closing member and the push button.

[0025] In the above-mentioned bathroom spray gun, as another technical solution, the front end portion of the water inlet body is protrudingly provided with two connecting portions that are both in the shape of arc petals and are arranged opposite to each other, the front ends of the two connecting portions are inserted into the rear end of the water body, the inner side of the rear end of the water body is provided with an annular boss, the outer side of the front end portion of the connecting portion is provided with a convex edge and the outer side of the rear end of the connecting portion is provided with a stopper, the annular boss is clamped between the convex edge and the stopper, the water inlet body is integrally fixedly connected with a sheet-like portion, the opening and closing member is located at the side of the sheet-like portion, the side of the sheet-like portion is protrudingly provided with a sliding portion, the sliding portion is arranged in a strip shape along the front and rear, the side of the opening and closing member is provided with a slide groove, and the sliding portion is located in the slide groove.

[0026] When assembling in this way, first put the opening and closing piece on the front end of the water inlet body, and fix the opening and closing piece to the water inlet body in the circumferential direction by the cooperation of the slide groove and the sliding part. Then insert the rear end of the water body into the opening and closing piece. During the insertion of the rear end of the water body, the two connecting parts protruding from the front end of the water inlet body will be directly inserted into the rear end of the water body. The convex edge on the outer side of the front end of the connecting part will jump over the annular convex shoulder located on the inner side of the rear end of the water body, so that the annular convex shoulder will be stuck between the convex edge and the block located on the outer side of the rear end of the connecting part, so that the water inlet body and the water body are fixedly connected together. Such a connection structure does not require the use of other connection parts, and is very convenient to assemble.

[0027] In addition, a sheet portion is integrally fixed to the water inlet body, and a sliding portion is protruding from the side of the sheet portion. The sliding portion is arranged in a strip shape along the front-to-back direction, and a sliding groove is provided on the side of the opening and closing member. The cooperation of the sliding groove and the sliding portion can be used to limit the circumferential angle of the opening and closing member to ensure the quick connection between the opening and closing member and the push button.

[0028] In the above-mentioned bathroom spray gun, the shell includes a handle and a head which is integrally connected to the front end of the handle and is arranged obliquely or vertically relative to the handle. A water outlet is inserted and fixed in the head. The water outlet includes a docking part. The front end of the water flow body is located in the head. The water flow body also includes a second water outlet. The second water outlet is arranged toward the water outlet, and the docking part is inserted into the second water outlet.

[0029] During actual assembly, the water flow body, water inlet body, opening and closing parts, digital display module and hydraulic generator are first connected to form an assembly, and then the assembly is fixed to the handle of the shell. Next, the water outlet head is directly plugged into the head of the shell, and the docking part of the water outlet head is inserted into the water outlet part 2 of the water flow body, thereby making the water flow body and the water outlet head conductive, thereby ensuring that water can eventually be sprayed out of the shell for use. Through the above arrangement, the assembly convenience of the bathroom spray gun is further improved.

[0030] A bathroom spray gun comprises a shell, a digital display module and a hydraulic generator which are both arranged in the shell and electrically connected, an opening and closing piece is also arranged in the shell, and a push button is also arranged outside the shell, characterized in that a water inlet body and a water flow body are arranged in the shell from back to front, the water inlet body and the water flow body are plugged or clamped and fixed, and the opening and closing piece is slidably arranged between the two along the front and back, the digital display module is fixed on the side of the water flow body and the hydraulic generator is fixed in the water inlet body, the opening and closing piece is cylindrical with openings at both ends, the opening and closing piece has a stepped inner hole which is small in the front and large in the back, the opening and closing piece is simultaneously sleeved on the front end of the water inlet body and the rear end of the water flow body, a water inlet is arranged on the side of the rear end of the water flow body and a sealing ring four is sleeved and fixed, the sealing ring four is located behind the water inlet and abuts against the front hole wall of the step-shaped inner hole to form a seal, a strip-shaped makeshift groove is arranged along the front and back of the side of the shell, the push button passes through the makeshift groove and is fixed to the opening and closing piece.

[0031] When in use, connect the bathroom spray gun to the water pipe. When the bathroom spray gun is in the closed state, the sealing ring 4 is located in the front part of the step-shaped inner hole of the opening and closing part, and the sealing ring 4 abuts against the front hole wall of the step-shaped inner hole of the opening and closing part to form a seal. At this time, the water inlet is blocked in front of the sealing ring 1, so that the water from the water inlet body cannot flow into the water flow body through the water inlet. When it is necessary to open, the user pushes the push button forward to drive the opening and closing part to slide forward. The positions of the water inlet body and the water flow body are fixed. As the opening and closing part slides forward, the sealing ring 4 and the water outlet will be located in the rear part of the step-shaped inner hole. At this time, the sealing ring 4 no longer forms a sealing effect and loses the function of blocking water. In this way, the water from the water inlet body can flow smoothly into the water flow body through the water inlet. In the process of water flowing, it will drive the impeller in the hydroelectric generator to rotate, thereby realizing power generation to power the digital display module to display the water temperature.

[0032] The bathroom spray gun is provided with a fixedly connected water inlet body and a water flow body in an outer shell and an opening and closing member is provided in a cylindrical shape with openings at both ends, the opening and closing member has a stepped inner hole which is small at the front and large at the rear, the opening and closing member is simultaneously sleeved on the front end of the water inlet body and the rear end of the water flow body, the rear end side of the water flow body is provided with a water inlet and sleeved and fixed with a sealing ring four, the sealing ring four is located behind the water outlet and abuts against the hole wall with the smaller hole diameter in the stepped inner hole to form a seal, so that the water inlet body and the water flow body can be connected or cut off when the opening and closing member slides forward and backward, that is to say, the water inlet body, the opening and closing member and the water flow body form a modular component with a water path inside and capable of realizing a water path cutting-off function (during actual assembly, the opening and closing member can be first sleeved on the outside of the front end of the water inlet body, and then the rear end of the water flow body can be inserted into the opening and closing member, and the water flow body and the water inlet body are directly plugged or clamped and fixed). On the basis that the modular component has its own water channel inside, power generation can be generated by directly fixing the hydroelectric generator in the water inlet body, and the water temperature can be displayed by directly fixing the digital display module on the side of the water body. After this combination, the opening and closing parts, the hydroelectric generator and the digital display module no longer need to be separately installed and fixed in the shell and connected accordingly as before. They can be directly assembled outside the shell and then installed into the shell as a whole. Finally, the push button can be passed through the give way groove on the side of the shell to connect with the opening and closing parts. While realizing the water temperature display function, it also solves the problem of inconvenient assembly caused by this.

[0033] Compared with the prior art, the present bathroom spray gun has a water inlet and a water flow body which are fixedly connected in the shell and an opening and closing member which is open at both ends. The opening and closing member has a stepped inner hole which is larger at the front and smaller at the back. The opening and closing member is simultaneously sleeved on the front end of the water inlet and the rear end of the water flow body. A water outlet is provided on the front side of the water inlet and a sealing ring is sleeved and fixed thereon. The sealing ring is located in front of the water outlet and abuts against the hole wall with a smaller hole diameter in the stepped inner hole to form a seal. In this way, the water inlet and the water flow body can be connected or disconnected when the opening and closing member slides forward and backward. That is to say, the water inlet, the opening and closing member and the water flow body form an internal waterway and A modular component that can realize the water channel cutting-off function, on this basis, can generate electricity by directly fixing the hydroelectric generator in the water inlet body, and can display the water temperature by directly fixing the digital display module on the side of the water body. After this combination, the opening and closing parts, the hydroelectric generator and the digital display module no longer need to be installed and fixed separately in the outer shell and connected accordingly as before. They can be directly assembled outside the outer shell and then installed into the outer shell as a whole. Finally, the push button can be passed through the give way groove on the side of the outer shell to connect with the opening and closing parts. While realizing the water temperature display function, the problem of inconvenient assembly caused by this is well solved. BRIEF DESCRIPTION OF THE DRAWINGS

The front end of the water outlet 5d is also sleeved and fixed with a sealing ring 10, which is located behind the water outlet 5b. The sealing ring 10 abuts against the rear hole wall of the stepped inner hole 4a to form a seal, and the sealing ring 10 is mainly used to prevent the water coming out of the water outlet 5b from leaking directly backwards. The water-passing body 6 includes a cylindrical water inlet 6c arranged along the front-back direction, the water inlet 6c is located in the opening and closing member 4, the outer diameter of the water inlet 6c matches the front aperture of the step-type inner hole 4a, and a sealing ring 11 is fixedly sleeved on the outer side of the rear end of the water inlet 6c, and the sealing ring 11 abuts against the front hole wall of the step-type inner hole 4a to form a seal, and the sealing ring 11 is mainly used to prevent the water coming out of the water outlet 5b from leaking directly from the gap between the rear end of the water-passing body 6 and the opening and closing member 4. The head 1b of the housing 1 is inclined or vertically arranged relative to the handle 1a, the front end of the water-passing body 6 is located in the head 1b, and a water outlet 12 is inserted and fixed in the head 1b, and the water outlet 12 includes a docking portion 12a, and the water-passing body 6 also includes a water outlet 6d, which is arranged toward the water outlet 12, and the docking portion 12a is inserted into the water outlet 6d.

[0048] Furthermore, if Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the water inlet body 5 also includes a long strip-shaped connecting piece 5e arranged along the front-to-back direction, the water outlet portion 5d is located on one side of the connecting piece 5e, and there is a clearance between the two along the radial direction of the water outlet portion 5d for the opening and closing member 4 to be sleeved outside the water outlet portion 5d, and the front end of the connecting piece 5e is plugged or snap-fitted to the water flow body 6. The side of the opening and closing member 4 is provided with a mating portion 4b protruding from the side, and the push button 7 is fixed to the mating portion 4b. The side of the connecting piece 5e is provided with a guide strip 5e1 along its length direction, and the side of the opening and closing member 4 is provided with a guide groove 4c, and the guide strip 5e1 is located in the guide groove 4c. Through the cooperation of the guide strip 5e1 and the guide groove 4c, it can be ensured that the opening and closing member 4 can slide in the front and rear directions to realize the opening or closing of the bathroom spray gun; and it can also ensure that the opening and closing member 4 and the connecting piece 5e are circumferentially fixed, thereby limiting the angle of the opening and closing member 4 along the circumferential direction to ensure the rapid connection of the opening and closing member 4 and the push button 7. In this embodiment, the side of the water flow body 6 is provided with an insert 6e protruding from the side, and the side of the connecting piece 5e is provided with a slot 5e2 near the front end, and the insert 6e is inserted into the slot 5e2 to connect the connecting piece 5e with the water flow body 6. There are two connecting pieces 5e in total, and the two connecting pieces 5e are arranged opposite to each other. The opening and closing member 4 is located between the two connecting pieces 5e, and the connection method between the opening and closing member 4 and the two connecting pieces 5e is the same. A clamping strip 1a2 is integrally connected to the handle 1a of the housing 1, and a clamping groove 5e3 is provided on the side of the connecting piece 5e. The clamping strip 1a2 is clamped in the clamping groove 5e3 so that the connecting piece 5e and the handle 1a are fixed together in a clamping manner. Of course, for the connection with the handle 1a, a clamping part can also be provided on the side of the connecting piece 5e, and a clamping groove is provided on the inner wall of the handle 1a, and the clamping part is clamped in the clamping groove. A strip-shaped guide portion 5f is integrally protruded at the center position of the front end portion of the water outlet portion 5d, and the cross-section of the guide portion 5f is cross-shaped. The guide portion 5f is inserted into the water inlet portion 6c of the water flow body 6. Because the cross-section of the guide portion 5f is cross-shaped, even if the guide portion 5f is inserted into the rear end of the water flow body 6, it will not be completely blocked. The main function of the guide portion 5f is to play a role in rapid guidance when connecting the water inlet body 5 and the water flow body 6, saving alignment time.

[0049] Furthermore, if Figure 1 , Figure 4 and Figure 5As shown, the hydroelectric generator 3 is connected to the male terminal 3a through a wire, the digital display module 2 is connected to the female terminal 2a through a wire, the side of the water body 6 is provided with a groove 6b, the digital display module 2 is positioned in the groove 6b, the groove bottom wall of the groove 6b is provided with a threading hole 6b1, the female terminal 2a is passed out to the outside of the threading hole 6b1, the water inlet 5 has a wire outlet hole 5c, the male terminal 3a is passed out to the outside of the water inlet 5 through the wire outlet hole 5c, the rear end of the water inlet 5 is internally threaded with a water inlet connector 13, the water inlet connector 13 extends out of the handle 1a and the water inlet connector 13 positions the hydroelectric generator 3 in the water inlet 5, the rear end of the water inlet connector 13 extends out of the handle 1a and is used to dock with the water pipe. The size of the male terminal 3a is smaller than the size of the wire outlet hole 5c, so that the male terminal 3a can be passed out of the wire outlet hole 5c (of course, sealing treatment is also required here to prevent water from leaking from here) to directly connect with the female terminal 2a of the digital display module 2. In this embodiment, the opening and closing member 4 is a plastic member, and a positioning portion 4d is integrally connected to the side of the opening and closing member 4. The positioning portion 4d and the matching portion 4b4b are arranged back to back, and the positioning portion 4d is arranged in a strip shape along the handle 1a. The cross-section of the positioning portion 4d is roughly U-shaped or C-shaped and the positioning portion 4d is elastic. The male terminal 3a and the female terminal 2a are both columnar and are stuck on the inner side of the positioning portion 4d after the two are connected.

[0050] When in use, the bathroom spray gun is connected to the water pipe through the rear end of the water inlet joint 13. Figure 7 As shown, when the bathroom spray gun is in the closed state, the sealing ring 18 is located in the rear part of the stepped inner hole 4a of the opening and closing member 4, and the sealing ring 18 abuts against the rear hole wall of the stepped inner hole 4a of the opening and closing member 4 to form a seal. At this time, the water outlet 5b is blocked behind the sealing ring 18 so that water cannot flow into the water body 6. When it is necessary to open, the user pushes the push button 7 backward to drive the opening and closing member 4 to slide backward. The positions of the water inlet 5 and the water body 6 are fixed. As the opening and closing member 4 slides backward, the sealing ring 18 and the water outlet 5b will be located in the front part of the stepped inner hole 4a. At this time, the sealing ring 18 no longer forms a seal and loses its function of blocking water. In this way, the water from the water pipe can smoothly flow into the water body 6 after flowing out of the water outlet 5b. This state is just like Figure 1 As shown. When water forms a flow, it will drive the impeller in the hydroelectric generator 3 to rotate, thereby generating electricity to power the digital display module 2. At the same time, the temperature sensor integrated in the hydroelectric generator 3 will detect the water temperature and the digital display module 2 will display the water temperature, so that the user can observe the current water temperature in real time through the transparent acrylic plate 9.

[0051] The bathroom spray gun is provided with a fixedly connected water inlet body 5 and a water flow body 6 in a shell 1, and the opening and closing member 4 is provided in a cylindrical shape with openings at both ends. The opening and closing member 4 has a stepped inner hole 4a which is larger at the front and smaller at the back. The opening and closing member 4 is simultaneously sleeved on the front end of the water inlet body 5 and the rear end of the water flow body 6. A water outlet 5b is provided on the front end side of the water inlet body 5 and a sealing ring 8 is sleeved and fixed thereon. The sealing ring 8 is located in front of the water outlet 5b and abuts against the hole wall with a smaller aperture in the stepped inner hole 4a to form a seal. In this way, the opening and closing member 4 can be slid forward and backward to realize conduction or isolation between the water inlet body 5 and the water flow body 6. That is to say, the water inlet body 5, the opening and closing member 4 and the water flow body 6 form a modular component with its own waterway inside and capable of realizing the waterway cutting function. On the basis of the water path inside the modular component, power generation can be performed by directly fixing the hydroelectric generator 3 in the water inlet body 5, and the water temperature can be displayed by directly fixing the digital display module 2 on the side of the water flow body 6. After this combination, the opening and closing member 4, the hydroelectric generator 3 and the digital display module 2 no longer need to be separately installed and fixed in the shell 1 and connected accordingly as before. They can be directly assembled outside the shell 1 and then installed into the shell 1 as a whole. Finally, the push button 7 can be passed through the make way groove 1a1 on the side of the shell 1 to connect with the opening and closing member 4. While realizing the water temperature display function, the problem of inconvenient assembly caused by this is well solved.

[0052] Specifically, during assembly, the hydroelectric generator 3 is placed into the rear end of the water inlet 5 and positioned with the water inlet joint 13. The male terminal 3a of the hydroelectric generator 3 is passed through the wire outlet hole 5c of the water inlet 5. The digital display module 2 is positioned in the groove 6b on the side of the water body 6. The female terminal 2a of the digital display module 2 is passed through the threading hole 6b1. Next, the opening and closing member 4 is sleeved outside the front end of the water inlet 5, and then the rear end of the water body 6 is inserted into the other end of the opening and closing member 4. The connecting piece 1 5e is connected to the water body 6 by inserting the insert piece 6e into the slot 5e2. In this way, the opening and closing member 4 can slide while being directly integrated with the water body 6 and the water inlet 5. Afterwards, the male terminal 3a is docked with the female terminal 2a and clamped in the positioning part 4d to be fixed. Thus, the digital display module 2, the hydroelectric generator 3, the opening and closing member 4, the water inlet 5 and the water passage 6 constitute a module, and finally the module only needs to be put into the handle 1a from the back to be fixed. Among them, the opening and closing member 4 is used to realize the opening or closing of the bathroom spray gun, and at the same time, it is used to realize the positioning after the male terminal 3a and the female terminal 2a are connected, that is, the opening and closing member 4 is a dual purpose.

[0057] The water control method in this embodiment is the same as that in the first embodiment, except that the difference lies in the connection method between the water passage body 6 and the water inlet body 5. When assembling by this method, the opening and closing member 4 is first sleeved outside the front end of the water inlet body 5, and the opening and closing member 4 is circumferentially fixed to the water inlet body 5 by the cooperation of the chute 4e and the sliding part 5h1. Then the rear end of the water passage body 6 is inserted into the opening and closing member 4. During the insertion of the rear end of the water passage body 6, the two connecting parts 5g protruding from the front end of the water inlet body 5 will be directly inserted into the rear end of the water passage body 6, and the convex edge 5g1 on the outer side of the front end of the connecting part 5g will jump over the annular convex shoulder 6f located on the inner side of the rear end of the water passage body 6, so that the annular convex shoulder 6f will be stuck between the convex edge 5g1 and the stopper 5g2 located on the outer side of the rear end of the connecting part 5g, so that the water inlet body 5 and the water passage body 6 are fixedly connected together. Such a connection structure does not require the use of other connecting parts 5g, and is very convenient to assemble.

[0058] Embodiment 4

[0059] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that: in this embodiment, the front end side of the water inlet body 5 is not provided with a water outlet 5b, and no sealing ring 1 8 and sealing ring 2 10 are sleeved and fixed thereon, the rear end side of the water body 6 is not provided with a sealing ring 3 11, the stepped inner hole 4a of the opening and closing member 4 is not larger at the front and smaller at the rear, the flow channel 2 6a does not directly penetrate the rear end of the water body 6, and the guide portion 5f is not provided at the center position of the front end of the water inlet body 5. Instead, the stepped inner hole 4a is small in front and large in the back, and the flow channel 5a directly passes through the front end of the water inlet body 5. A water inlet is provided on the rear end side of the water flow body 6 and is sleeved and fixed with a sealing ring 4. The sealing ring 4 is located behind the water inlet and abuts against the front hole wall of the stepped inner hole 4a to form a seal. When the bathroom spray gun is in the closed state, the sealing ring 4 is located in the front part of the stepped inner hole 4a of the opening and closing member 4, and the sealing ring 4 abuts against the front hole wall of the stepped inner hole 4a of the opening and closing member 4 to form a seal. At this time, the water inlet is blocked in front of the sealing ring 8, so that the water from the water inlet body 5 cannot flow into the water flow body 6 through the water inlet. When it needs to be opened, the user pushes the push button 7 forward to drive the opening and closing member 4 to slide forward. The positions of the water inlet body 5 and the water flow body 6 are fixed. As the opening and closing member 4 slides forward, the sealing ring four and the water outlet 5b will be located in the rear part of the stepped inner hole 4a. At this time, the sealing ring four no longer forms a sealing effect and loses the function of blocking water. In this way, the water from the water inlet body 5 can flow smoothly into the water flow body 6 through the water inlet. Furthermore, a sealing ring five is sleeved and fixed on the rear end side of the water inlet 6, and the sealing ring five is located in front of the water inlet. The sealing ring five abuts against the front hole wall of the step-shaped inner hole 4a to form a seal.
