Description

TECHNICAL FIELD

[0001] The utility model belongs to the bathroom technical field and relates to a bathroom spray gun. BACKGROUND

[0002] Most of the current 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. Previously, the spray gun was directly connected to cold water, which would not have much impact on cleaning the toilet or the ground around the toilet, but would cause discomfort when used to clean the body due to the low temperature. Therefore, a mixing valve with cold and hot water mixing function is now installed on the wall surface near the toilet, and the mixing valve is connected to the spray gun to provide mixed water, and the user can adjust the water temperature of the spray gun through the mixing valve to ensure the comfort when cleaning 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 realized by relying on its own switch, that is, the mixing valve is always open during normal use. The existing spray gun does not have a temperature display function, and the user cannot intuitively grasp the actual water temperature after turning it on, but can only rely on the skin to contact the water to perceive it, but if the water temperature is set too high in advance, it is easy to scald the skin, so it is not very convenient to use.

[0003] To solve this problem, there is a self-generating power shower on the market with a patent application number of 202223406180.2, which includes a shower body, a holding pipe is connected to the lower end of the shower body, a digital panel is fixedly installed on the top of the shower body, a small hydroelectric generator is fixedly arranged at the lower end of the shower body, the upper end outlet of the small hydroelectric generator is sealingly connected to the lower end inlet of the shower body, a wire port is arranged at the upper end of the small hydroelectric generator close to the rear side, a wire is led out from the wire port, the wire is located between the small hydroelectric generator and the digital panel, one end of the wire is connected to the digital panel, the other end of the wire is connected to the small hydroelectric generator, the digital panel is electrically connected between the wire and the small hydroelectric generator, a spray head is installed at the front end of the shower body, and the spray head is detachably connected to the shower body. The spray head includes a shower outer shell, a fixed disc is arranged inside the shower outer shell, an upper water outlet is arranged on the upper side of the fixed disc, and a lower water outlet is arranged on the lower side of the fixed disc. In addition, a switch is arranged on the shower body for controlling the opening and closing. When the shower is turned on, the flowing water can drive the small hydroelectric generator to generate electricity, and the electric quantity generated by the small hydroelectric generator can be transmitted to the digital panel through the wire, so that the digital panel realizes temperature display with the electric quantity of the small hydroelectric generator, thereby enabling the user to real-time master the water temperature and avoid scalding.

[0004] As can be seen from the accompanying diagrams in the instruction manual, the digital display panel, the small hydroelectric generator, and the switch are all installed separately during assembly. The internal space of the shower head is relatively small, requiring careful attention to avoid interference and misalignment between these components, making assembly inconvenient. In particular, the digital display panel and the small hydroelectric generator are difficult to assemble because they are connected by wires located inside the shower head. Therefore, the only possible steps are to install the small hydroelectric generator first, then pass the wires through the mounting point of the digital display panel, connect them, tuck the wires back into the shower head, and finally install and secure the digital display panel in its position. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a bathroom spray gun that solves the problem of inconvenient assembly in order to display water temperature.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A bathroom spray gun includes a housing and a digital display module and a water generator, both electrically connected and housed within the housing. The housing also includes an opening / closing component and a push button on the outside. The housing contains an inlet body and a through body arranged from back to front. The inlet body and through body are inserted or snapped together, and the opening / closing component slides between them. The digital display module is fixed to the side of the through body, and the water generator is fixed to the inlet body. The opening / closing component is a cylindrical shape with openings at both ends and has a stepped inner hole that is larger at the front and smaller at the back. The opening / closing component is simultaneously fitted onto the front end of the inlet body and the rear end of the through body. The front side of the inlet body has an outlet and a sealing ring is fitted and fixed thereon. The sealing ring is located in front of the outlet and abuts against the rear wall of the stepped inner hole to form a seal. The housing side has a strip-shaped clearance groove along its front and rear sides, and the push button passes through the clearance groove and is fixed to the opening / closing component.

[0008] When in use, connect this bathroom spray gun to the water pipe. With the spray gun closed, the sealing ring is located at the rear of the stepped inner hole of the opening / closing element, abutting against the rear wall of the stepped inner hole to form a seal. At this time, the water outlet is blocked behind the sealing ring, preventing water from flowing into the water passage. To open, the user pushes the knob backward, causing the opening / closing element to slide backward. The positions of the inlet and outlet remain fixed. As the opening / closing element slides backward, the sealing ring and outlet are positioned at the front of the stepped inner hole. At this point, the sealing ring no longer forms a seal and loses its water-blocking function, allowing water from the pipe to flow smoothly into the water passage after exiting the outlet. During the water flow, the impeller inside the hydroelectric generator rotates, generating electricity to power the digital display module for displaying the water temperature.

[0009] This bathroom spray gun features an inlet and a outlet body that are plugged in or snapped into place within the outer casing. The opening and closing mechanism is a cylindrical shape with openings at both ends. The opening and closing mechanism has a stepped inner hole that is larger at the front and smaller at the back. The opening and closing mechanism is fitted onto the front end of the inlet body and the rear end of the outlet body. The front side of the inlet body has an outlet and a sealing ring is fitted onto it. The sealing ring is located in front of the outlet and abuts against the wall of the smaller diameter hole in the stepped inner hole to form a seal. Thus, the opening and closing mechanism can slide back and forth to achieve either connection or disconnection between the inlet body and the outlet body. In other words, the inlet body, the opening and closing mechanism, and the outlet body form a modular component with an internal water passage that can achieve water passage cut-off function. (In actual assembly, the opening and closing mechanism can be fitted onto the front end of the inlet body first, and then the rear end of the outlet body can be inserted into the opening and closing mechanism, with the outlet body and the inlet body directly plugged in or snapped into place.) Based on the built-in water channel within this modular component, the hydroelectric generator can generate electricity by being directly fixed to the inlet body, and the digital display module can display the water temperature by being directly fixed to the side of the water passage body. This combination eliminates the need for the opening and closing components, hydroelectric generator, and digital display module to be installed and fixed separately in the outer casing and connected as before. They can be directly assembled on the outside of the casing, then installed as a whole into the casing, and finally the push button is connected to the opening and closing component by passing through the relief groove on the side of the casing. This not only realizes the water temperature display function, but also effectively solves the problem of inconvenient assembly.

[0010] In the aforementioned bathroom spray gun, the hydroelectric generator is connected to a columnar male terminal via a wire, and the digital display module is connected to a columnar female terminal via a wire. A positioning part is integrally fixed to the side of the opening and closing part along its length. The cross-section of the positioning part is approximately horizontally U-shaped or C-shaped and the positioning part is elastic. The male terminal is connected to the female terminal and locked inside the positioning part.

[0011] The male and female terminals allow for quick electrical connection between the hydroelectric generator and the digital display module. An integrated positioning part is fixed to the side of the opening / closing component. This positioning part is elongated along the handle, with a roughly U-shaped or C-shaped cross-section and is elastic. After the male and female terminals mate, they are locked inside the positioning part, ensuring a secure hold and preventing interference during the insertion of the module (comprising the digital display module, hydroelectric generator, opening / closing component, water passage body, and water inlet body) into the handle. Furthermore, this positioning of the male and female terminals prevents them from shaking and generating noise during handheld use of the bathroom spray gun.

[0012] In other words, the opening and closing component serves both to turn the bathroom spray gun on and off, and to position the male and female terminals after they are connected. Therefore, the opening and closing component has two functions.

[0013] In the aforementioned bathroom spray gun, the side of the water inlet body is provided with a groove, the digital display module is positioned in the groove, the bottom wall of the groove is provided with a wire through hole, the female terminal extends out to the outside of the wire through hole, the water inlet body is provided with a wire outlet hole, and the rear end of the water inlet body is internally threaded with a water inlet connector, the water inlet connector extends out of the outer shell and the water inlet connector positions the water generator in the water inlet body.

[0014] During installation, after positioning the digital display module in the groove, pass the female terminal through the wiring port. Place the hydroelectric generator into the rear end of the inlet body and position it using the inlet connector. Pass the male terminal through the outlet hole, and then directly connect the female and male terminals. This setup allows the digital display module, fixed to the side of the inlet body, to easily connect or disconnect from the hydroelectric generator fixed within the inlet body.

[0015] In the aforementioned bathroom spray gun, the water inlet body includes a cylindrical water outlet section 1 arranged in the front-to-back direction and a strip-shaped connecting piece 1 arranged in the front-to-back direction. The water outlet and the sealing ring 1 are both located on the water outlet section 1. The water outlet section 1 is located on one side of the connecting piece 1, and there is a clearance gap between the two along the radial direction of the water outlet section 1, which allows the opening and closing element to be sleeved on the outside of the water outlet section 1. The front end of the connecting piece 1 is inserted into or snapped into the water inlet body for fixation.

[0016] During assembly, first, the opening and closing component is fitted onto the outside of the water outlet section. Then, the rear end of the water inlet body is directly inserted into the opening and closing component and fixed to the water inlet body by insertion or snap-fitting the front end of the connecting piece, thus connecting the water inlet body, the opening and closing component, and the water inlet body into a whole. The connecting piece is elongated in the front-to-back direction, which allows the water inlet body to be inserted or snap-fitted to the water inlet body after the opening and closing component is fitted onto it.

[0017] In the aforementioned bathroom spray gun, the opening and closing component has a protruding mating part on its side, the push button is fixed to the mating part, the side of the connecting piece is provided with a guide strip along its length, the side of the opening and closing component is provided with a guide groove, and the guide strip is located in the guide groove.

[0018] The push button connects to a mating part protruding from the side of the opening / closing element, thus requiring specific circumferential positioning. By providing a guide strip along the length of the connecting piece and a corresponding guide groove on the side of the opening / closing element, the guide strip is directly inserted into the guide groove when the opening / closing element is fitted over the water outlet of the inlet body. This ensures that the opening / closing element can slide in the front-back direction to open or close the bathroom spray gun, while also circumferentially fixing the opening / closing element to the connecting piece to limit the circumferential angle of the opening / closing element, thus ensuring quick connection between the opening / closing element and the push button.

[0019] With this setup, the connecting piece has two functions: one is to fix the water inlet body and the water outlet body together, so that the water inlet body, the water outlet body and the opening and closing parts are connected together to form a component; the other is to circumferentially limit the mating part on the side of the opening and closing parts, so as to ensure the quick connection between the opening and closing parts and the push button.

[0020] In one of the aforementioned bathroom spray guns, as another technical solution, the water-passing body includes a cylindrical water inlet section two arranged in the front-to-back direction and a strip-shaped connecting piece two arranged in the front-to-back direction. The water inlet section two is located on one side of the connecting piece two, and there is a clearance gap between the two along the radial direction of the water inlet section two, which allows the opening and closing parts to be sleeved on the outside of the water inlet section two. The rear end of the connecting piece two is inserted into or snapped into the water inlet body for fixation.

[0021] During assembly, first, the opening and closing component is fitted onto the outside of the second water inlet section. Then, the rear front end of the water inlet body is directly inserted into the opening and closing component and fixed to the water inlet body by insertion or snap-fitting the rear end of the second connecting piece, so that the water passage body, the opening and closing component, and the water inlet body can be connected into a whole. Among them, the second connecting piece is long and strip-shaped along the front and back direction. This shape allows the water passage body to be inserted or snap-fitted to the water inlet body after the opening and closing component is fitted onto it.

[0022] In the aforementioned bathroom spray gun, the side of the opening and closing component is provided with a mating part, the push button is fixed to the mating part, the side of the connecting piece two is provided with a guide strip two along its length direction, the side of the opening and closing component is provided with a guide groove two, and the guide strip two is located in the guide groove two.

[0023] The push button is connected to a mating part protruding from the side of the opening / closing component, so there are requirements for its circumferential position. By setting a guide strip two along its length on the side of the connecting piece two and a corresponding guide groove two on the side of the opening / closing component, when the opening / closing component is fitted over the water inlet part two of the water-passing body, the guide strip two is directly inserted into the guide groove two. This ensures that the opening / closing component can slide in the front-back direction to open or close the bathroom spray gun, and also allows the opening / closing component and the connecting piece two to be circumferentially fixed to limit the circumferential angle of the opening / closing component, thus ensuring a quick connection between the opening / closing component and the push button.

[0024] With this setup, the connecting piece 2 serves two purposes: one is to fix the water inlet body and the water outlet body together, so that the water inlet body, the water outlet body, and the opening and closing parts are connected together to form a single component; the other is to circumferentially limit the mating part on the side of the opening and closing parts, ensuring quick connection between the opening and closing parts and the push button.

[0025] In one of the aforementioned bathroom spray guns, as another technical solution, the front end of the water inlet body is provided with two connecting parts that are both arc-shaped and opposite to each other. The front ends of the two connecting parts are inserted into the rear end of the water inlet body. The inner side of the rear end of the water inlet body is provided with an annular shoulder. The outer side of the front end of the connecting part is provided with a raised edge, and the outer side of the rear end of the connecting part is provided with a stop block. The annular shoulder is stuck between the raised edge and the stop block. The water inlet body is integrally fixed with a plate-shaped part. The opening and closing part is located on the side of the plate-shaped part. The side of the plate-shaped part is provided with a sliding part. The sliding part is arranged in a strip shape along the front and back. The side of the opening and closing part is provided with a sliding groove, and the sliding part is located in the sliding groove.

[0026] When assembling using this method, the opening and closing component is first fitted over the front end of the inlet body, and the opening and closing component is circumferentially fixed to the inlet body by the cooperation of the sliding groove and the sliding part. Then, the rear end of the water passage body is inserted into the opening and closing component. During the insertion of the rear end of the water passage body, the two connecting parts protruding from the front end of the inlet body will directly insert into the rear end of the water passage body. The protruding edge on the outer side of the front end of the connecting part will jump over the annular shoulder located on the inner side of the rear end of the water passage body. In this way, the annular shoulder will be locked between the protruding edge and the stop block located on the outer side of the rear end of the connecting part, thereby fixing the inlet body and the water passage body together. This connection structure does not require the use of other connecting parts, making assembly very convenient.

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

[0028] In the aforementioned bathroom spray gun, the outer shell includes a handle and a head integrally fixed to the front end of the handle and inclined or vertically arranged relative to the handle. A water outlet is inserted and fixed inside the head. The water outlet includes a docking part. The front end of the water passage body is located inside the head. The water passage body also includes a second water outlet, which is arranged facing the water outlet. The docking part is inserted into the second water outlet.

[0029] In actual assembly, the water-passing body, water inlet body, opening and closing mechanism, digital display module, and hydroelectric generator are first connected to form a single component, which is then fixed into the handle of the outer casing. Next, the water outlet head is directly inserted and fixed into the head of the outer casing. The mating part of the water outlet head inserts into the water outlet section of the water-passing body, thereby creating a connection between the water-passing body and the water outlet head, ensuring that water can ultimately be sprayed out of the casing for use. This design further improves the ease of assembly for the bathroom spray gun.

[0030] A bathroom spray gun includes a housing and a digital display module and a water generator, both electrically connected and housed within the housing. The housing also includes an opening / closing component and a push button on the outside. The housing contains an inlet body and a through body arranged from back to front. The inlet body and through body are inserted or snapped together, and the opening / closing component slides between them. The digital display module is fixed to the side of the through body, and the water generator is fixed to the inlet body. The opening / closing component is cylindrical with openings at both ends and has a stepped inner hole that is smaller at the front and larger at the back. The opening / closing component is simultaneously fitted onto the front end of the inlet body and the rear end of the through body. The rear end of the through body has an inlet and a sealing ring four is fitted and fixed thereon. The sealing ring four is located behind the inlet and abuts against the front wall of the stepped inner hole to form a seal. The housing has a strip-shaped clearance groove along its front and rear sides, and the push button passes through the clearance groove and is fixed to the opening / closing component.

[0031] When in use, connect this bathroom spray gun to the water pipe. With the spray gun closed, sealing ring four is located in the front part of the stepped inner hole of the opening and closing device, forming a seal against the front wall of the stepped inner hole. At this time, the water inlet is blocked in front of sealing ring one, preventing water from flowing into the water passage body. To open, the user pushes the knob forward, causing the opening and closing device to slide forward. The positions of the water inlet and water passage body remain fixed. As the opening and closing device slides forward, sealing ring four and the water outlet are located in the rear part of the stepped inner hole. At this time, sealing ring four no longer forms a seal and loses its water-blocking function, allowing water from the water inlet to flow smoothly into the water passage body. During the water flow, the impeller inside the hydroelectric generator rotates, generating electricity to power the digital display module for displaying the water temperature.

[0032] This bathroom spray gun features a fixedly connected inlet and outlet water body within its outer casing, with a cylindrical opening at both ends for the opening and closing mechanism. The opening and closing mechanism has a stepped inner hole that is smaller at the front and larger at the back. The opening and closing mechanism is fitted onto the front end of the inlet water body and the rear end of the outlet water body. The rear end of the outlet water body has an inlet water port and a sealing ring four is fitted and fixed thereon. The sealing ring four is located behind the outlet water port and abuts against the wall of the smaller diameter hole in the stepped inner hole to form a seal. Thus, the opening and closing mechanism can slide back and forth to achieve either connection or disconnection between the inlet water body and the outlet water body. In other words, the inlet water body, the opening and closing mechanism, and the outlet water body form a modular component with an internal water channel that can achieve water channel cut-off function. (During actual assembly, the opening and closing mechanism can be fitted onto the front end of the inlet water body first, and then the rear end of the outlet water body can be inserted into the opening and closing mechanism, with the outlet water body and the inlet water body directly forming a plug-in or snap-fit ​​connection for fixation.) Based on the built-in water channel within this modular component, the hydroelectric generator can generate electricity by being directly fixed to the inlet body, and the digital display module can display the water temperature by being directly fixed to the side of the water passage body. This combination eliminates the need for the opening and closing components, hydroelectric generator, and digital display module to be installed and fixed separately in the outer casing and connected as before. They can be directly assembled on the outside of the casing, then installed as a whole into the casing, and finally the push button is connected to the opening and closing component by passing through the relief groove on the side of the casing. This not only realizes the water temperature display function, but also effectively solves the problem of inconvenient assembly.

[0033] Compared with existing technologies, this bathroom spray gun features a fixedly connected inlet and outlet water body within its outer casing. The opening and closing mechanism is a cylindrical shape with openings at both ends. The opening and closing mechanism has a stepped inner hole, wider at the front and narrower at the rear. It is fitted onto both the front end of the inlet water body and the rear end of the outlet water body. An outlet water body is located on the front side of the inlet water body, and a sealing ring is fixedly fitted onto it. The sealing ring is located in front of the outlet water body and abuts against the wall of the smaller diameter hole in the stepped inner hole to form a seal. Thus, sliding the opening and closing mechanism back and forth allows for the connection or disconnection between the inlet water body and the outlet water body. In other words, the inlet water body, opening and closing mechanism, and outlet water body form a device with its own internal water passage. This modular component enables water circuit shut-off. It generates electricity by directly fixing a hydroelectric generator to the inlet body and displays water temperature by directly fixing a digital display module to the side of the water passage. This combination eliminates the need for separate installation and connection of the opening / closing mechanism, hydroelectric generator, and digital display module within the original housing. They can be assembled on the outside of the housing, then inserted into the housing as a whole, and finally the push button is connected to the opening / closing mechanism by passing through the recessed groove on the side of the housing. This effectively solves the assembly inconvenience problem while providing water temperature display functionality. Attached Figure Description

Detailed Implementation

[0044] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0045] Example 1

[0046] like Figures 1-6 As shown, a bathroom spray gun includes a housing 1, a digital display module 2, and a hydroelectric generator 3, both housed within the housing 1. The digital display module 2 and the hydroelectric generator 3 are electrically connected. In this embodiment, the hydroelectric generator 3 integrates a temperature sensor. The hydroelectric generator 3 is an existing structure, and how the hydroelectric generator 3 generates electricity and detects temperature is prior art, as detailed in a previously published patent application (patent number 201620298699.9) on a hydroelectric LED module. The housing 1 also includes an opening / closing element 4 for controlling the opening and closing of the bathroom spray gun. A push button 7 is also provided outside the housing 1. The housing 1 has a handle 1a and a head 1b integrally fixed to the front end of the handle 1a. The handle 1a contains a water inlet 5 and a water passage 6 arranged from back to front. The water inlet 5 and the water passage 6 are inserted or snapped together, and the opening / closing element 4 is slidably disposed between them. The opening and closing element 4 is a cylindrical shape with openings at both ends. It has a stepped inner hole 4a, which is larger at the front and smaller at the back. The opening and closing element 4 is fitted onto both the front end of the inlet body 5 and the rear end of the through body 6. The inlet body 5 has a first flow channel 5a, and the through body 6 has a second flow channel 6a, which extends through the rear end of the through body 6. The front side of the inlet body 5 has an outlet 5b, which communicates with the first flow channel 5a. A sealing ring 8 is also fitted and fixed to the front side of the inlet body 5. The sealing ring 8 is located in front of the outlet 5b and abuts against the rear wall of the stepped inner hole 4a to form a seal. The handle 1a of the outer casing 1 has a strip-shaped clearance groove 1a1 along its front and rear sides. The push button 7 passes through the clearance groove 1a1 and is fixed to the opening and closing element 4. The handle 1a of the outer casing 1 has a window corresponding to the position of the digital display module 2. An acrylic transparent plate 9 is fixed inside the window. The acrylic transparent plate 9 and the push button 7 are located on the same side of the handle 1a.

[0047] In this embodiment, as Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the water inlet body 5 includes a cylindrical water outlet section 5d arranged along the front-to-back direction. A water outlet 5b and a sealing ring 8 are both located on the water outlet section 5d. The outer diameter of the water outlet section 5d matches the rear diameter of the stepped inner hole 4a. A sealing ring 2 10 is also fitted and fixed to the front end of the water outlet section 5d. The sealing ring 2 10 is located behind the water outlet 5b and abuts against the rear wall of the stepped inner hole 4a to form a seal. The sealing ring 2 10 is mainly used to prevent water from the water outlet 5b from leaking directly to the rear. The water-passing body 6 includes a cylindrical water inlet section 6c arranged along the front-to-back direction. The water inlet section 6c is located inside the opening and closing member 4. The outer diameter of the water inlet section 6c matches the front diameter of the stepped inner hole 4a. A sealing ring 11 is sleeved and fixed on the outer side of the rear end of the water inlet section 6c. The sealing ring 11 abuts against the front hole wall of the stepped inner hole 4a to form a seal. The sealing ring 11 is mainly used to prevent water from the outlet 5b from leaking outward 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 outer shell 1 is inclined or vertically arranged relative to the handle 1a. The front end of the water-passing body 6 is located inside the head 1b. A water outlet head 12 is inserted and fixed inside the head 1b. The water outlet head 12 includes a docking part 12a. The water-passing body 6 also includes a water outlet section 6d, which is arranged facing the water outlet head 12. The docking part 12a is inserted into the water outlet section 6d.

[0048] Furthermore, such as 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 in the front-back direction. The water outlet part 5d is located on one side of the connecting piece 5e, and there is a clearance gap between the two along the radial direction of the water outlet part 5d, which allows the opening and closing member 4 to be sleeved outside the water outlet part 5d. The front end of the connecting piece 5e is inserted or snapped into the water passage body 6 for fixation. The opening / closing component 4 has a protruding mating part 4b on its side, and the push button 7 is fixed to the mating part 4b. The side of the connecting piece 5e has a guide strip 5e1 along its length direction, and the side of the opening / closing component 4 has a guide groove 4c. 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 / closing component 4 can slide in the front-back direction to realize the opening or closing of the bathroom spray gun; it can also ensure that the opening / closing component 4 and the connecting piece 5e are circumferentially fixed, thereby limiting the angle of the opening / closing component 4 in the circumferential direction to ensure the quick connection between the opening / closing component 4 and the push button 7. In this embodiment, the side of the water passage body 6 has a protruding insert 6e, and the side of the connecting piece 5e has a slot 5e2 near the front end. The insert 6e is inserted into the slot 5e2 to connect the connecting piece 5e to the water passage body 6. There are two connecting pieces 5e in total, arranged opposite each other. The opening and closing element 4 is located between the two connecting pieces 5e, and the connection method between the opening and closing element 4 and the two connecting pieces 5e is the same. A retaining strip 1a2 is integrally fixed inside the handle 1a of the outer casing 1. The side of the connecting piece 5e is provided with a retaining groove 5e3. The retaining strip 1a2 is engaged in the retaining groove 5e3, so that the connecting piece 5e and the handle 1a are fixed together by a snap-fit ​​method. Of course, for the connection with the handle 1a, a retaining part can also be provided on the side of the connecting piece 5e, and a retaining groove can be provided on the inner wall of the handle 1a, with the retaining part engaging in the retaining groove. At the center of the front end of the water outlet 5d, a strip-shaped guide part 5f is integrally protruding. The cross-section of the guide part 5f is cross-shaped. The guide part 5f is inserted into the water inlet 6c of the water passage body 6. Because the cross-section of the guide part 5f is cross-shaped, even if the guide part 5f is inserted into the rear end of the water passage body 6, it will not completely block it. The main function of the guide part 5f is to provide quick guidance when connecting the water inlet body 5 and the water passage body 6, saving alignment time.

[0049] Furthermore, such as Figure 1 , Figure 4 and Figure 5As shown, the hydroelectric generator 3 is connected to a male terminal 3a via a wire, and the digital display module 2 is connected to a female terminal 2a via a wire. A groove 6b is provided on the side of the water inlet 6, and the digital display module 2 is positioned within the groove 6b. A wire-passing opening 6b1 is provided on the bottom wall of the groove 6b, through which the female terminal 2a extends. The water inlet 5 has an outlet hole 5c, through which the male terminal 3a extends. An inlet connector 13 is internally threaded to the rear end of the water inlet 5. The inlet connector 13 extends beyond the handle 1a and positions the hydroelectric generator 3 within the water inlet 5. The rear end of the inlet connector 13 extends beyond the handle 1a and is used to connect to a water pipe. The male terminal 3a is smaller than the outlet hole 5c, allowing it to pass through (and be sealed to prevent water leakage) and directly connect to the female terminal 2a of the digital display module 2. In this embodiment, the opening and closing part 4 is a plastic part. The side of the opening and closing part 4 is integrally fixed with a positioning part 4d. The positioning part 4d is arranged opposite to the mating part 4b4b. The positioning part 4d is arranged in a strip shape along the handle part 1a. The cross-section of the positioning part 4d is approximately U-shaped or C-shaped and the positioning part 4d is elastic. The male terminal 3a and the female terminal 2a are both columnar and are locked inside the positioning part 4d after they are mated.

[0050] When using, connect this bathroom spray gun to the water pipe via the rear end of the water inlet connector 13. For example... Figure 7 As shown, when the bathroom spray gun is closed, the sealing ring 8 is located behind the stepped inner hole 4a of the opening and closing component 4. The sealing ring 8 abuts against the rear wall of the stepped inner hole 4a of the opening and closing component 4 to form a seal. At this time, the water outlet 5b is blocked behind the sealing ring 8, preventing water from flowing into the water passage 6. When it needs to be opened, the user pushes the push button 7 backward, causing the opening and closing component 4 to slide backward. The positions of the water inlet 5 and the water passage 6 remain fixed. As the opening and closing component 4 slides backward, the sealing ring 8 and the water outlet 5b are located in front of the stepped inner hole 4a. At this time, the sealing ring 8 no longer forms a seal and loses its function of blocking water. In this way, the water from the water pipe can flow smoothly into the water passage 6 after flowing out of the water outlet 5b. This state is as follows: Figure 1 As shown, during the water flow process, the impeller inside the hydroelectric generator 3 is driven to rotate, thereby generating electricity to power the digital display module 2. At the same time, the temperature sensor integrated on the hydroelectric generator 3 detects the water temperature and displays it through the digital display module 2, so that the user can observe the current water temperature in real time through the transparent acrylic plate 9.

[0051] This bathroom spray gun has a water inlet 5 and a water passage 6 fixedly connected inside the outer casing 1, and the opening and closing part 4 is set as a cylindrical shape with open ends. The opening and closing part 4 has a stepped inner hole 4a that is larger at the front and smaller at the back. The opening and closing part 4 is sleeved on the front end of the water inlet 5 and the rear end of the water passage 6. The front side of the water inlet 5 has a water outlet 5b and a sealing ring 8 is fixedly sleeved on it. The sealing ring 8 is located in front of the water outlet 5b and abuts against the wall of the smaller hole in the stepped inner hole 4a to form a seal. In this way, the opening and closing part 4 can slide back and forth to realize the conduction or isolation between the water inlet 5 and the water passage 6. That is to say, the water inlet 5, the opening and closing part 4 and the water passage 6 form a modular component with its own water channel and can realize the water channel cut-off function. Based on the built-in water channel inside this modular component, the water generator 3 can generate electricity by being directly fixed inside the water inlet 5, and the digital display module 2 can display the water temperature by being directly fixed to the side of the water passage 6. After this combination, the opening and closing component 4, the water generator 3 and the digital display module 2 no longer need to be installed and fixed separately in the outer shell 1 and connected accordingly, as before. They can be directly assembled and fitted on the outside of the outer shell 1 and then installed as a whole into the outer shell 1. Finally, the push button 7 is connected to the opening and closing component 4 by passing through the relief groove 1a1 on the side of the outer shell 1. This not only realizes the water temperature display function, but also solves the problem of inconvenient assembly.

[0052] During assembly, the hydroelectric generator 3 is placed inside the rear end of the water inlet body 5 and positioned using the water inlet connector 13. The male terminal 3a of the hydroelectric generator 3 passes through the outlet hole 5c of the water inlet body 5. The digital display module 2 is positioned in the groove 6b on the side of the water passage body 6, and the female terminal 2a of the digital display module 2 passes through the wire passage 6b1. Next, the opening and closing member 4 is fitted over the front end of the water inlet body 5, and then the rear end of the water passage body 6 is inserted into the other end of the opening and closing member 4. The connecting piece 5e is connected to the water passage body 6 by inserting the insert 6e into the slot 5e2. In this way, the opening and closing member 4 can slide while being directly integrated with the water passage body 6 and the water inlet body 5. Afterward, the male terminal 3a and the female terminal 2a are mated and locked in the positioning part 4d to form a fixed position. Thus, the digital display module 2, the hydroelectric generator 3, the opening and closing component 4, the water inlet 5, and the water passage 6 constitute a module. Finally, the module is simply inserted into the handle 1a from the rear to secure it. The opening and closing component 4 is used to open or close the bathroom spray gun, and also to position the male terminal 3a after it is connected to the female terminal 2a. In other words, the opening and closing component 4 serves a dual purpose.

[0053] Example 2

[0054] This embodiment has the same structure and principle as Embodiment 1, except that: in this embodiment, the inlet body 5 does not have a connecting piece 5e, but the water passage body 6 also includes a long strip-shaped connecting piece 2 arranged in the front-to-back direction. The second water inlet 6c is located on one side of the connecting piece 2, and there is a clearance gap between them along the radial direction of the second water inlet 6c, which allows the opening and closing member 4 to be sleeved on the outside of the second water inlet 6c. The rear end of the connecting piece 2 is inserted or snapped into the water inlet body 5 for fixation. The side of the connecting piece 2 is provided with a guide strip 2 along its length direction, and the side of the opening and closing member 4 is provided with a guide groove 2, with the guide strip 2 located in the guide groove 2.

[0055] Example 3

[0056] This embodiment is basically the same as embodiment one in structure and principle, except that: Figure 8 and Figure 9 As shown, in this embodiment, no guide portion 5f is provided at the center of the front end of the water inlet body 5. Two connecting portions 5g, both arc-shaped and opposite to each other, are provided at the front end of the water inlet body 5. The front ends of the two connecting portions 5g are inserted into the rear end of the water passage body 6. An annular shoulder 6f is provided on the inner side of the rear end of the water passage body 6. A flange 5g1 is provided on the outer side of the front end of the connecting portion 5g and a stop block 5g2 is provided on the outer side of the rear end of the connecting portion 5g. The annular shoulder 6f is stuck between the flange 5g1 and the stop block 5g2. A sheet-like portion 5h is integrally fixed to the water inlet body 5. The opening and closing member 4 is located on the side of the sheet-like portion 5h. A sliding portion 5h1 is provided on the side of the sheet-like portion 5h. The sliding portion 5h1 is arranged in a strip shape along the front and back. A groove 4e is provided on the side of the opening and closing member 4. The sliding portion 5h1 is located in the groove 4e.

[0057] The water control method in this embodiment is the same as in Embodiment 1, except for the connection method between the water passage body 6 and the water inlet body 5. When assembling using this method, the opening / closing component 4 is first fitted over the front end of the water inlet body 5, and the opening / closing component 4 is circumferentially fixed to the water inlet body 5 by the cooperation of the sliding groove 4e and the sliding part 5h1. Then, the rear end of the water passage body 6 is inserted into the opening / closing component 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 are directly inserted into the rear end of the water passage body 6. The protruding edge 5g1 on the outer side of the front end of the connecting part 5g jumps over the annular shoulder 6f located on the inner side of the rear end of the water passage body 6. Thus, the annular shoulder 6f is locked between the protruding edge 5g1 and the stop block 5g2 located on the outer side of the rear end of the connecting part 5g, thereby fixing the water inlet body 5 and the water passage body 6 together. This connection structure also eliminates the need for other connecting parts 5g, making assembly very convenient.

[0058] Example 4

[0059] This embodiment is basically the same as the first embodiment in terms of structure and principle. The difference is that: in this embodiment, the front end of the water inlet 5 does not have an outlet 5b and is not fitted with sealing ring 1 8 and sealing ring 2 10. The rear end of the water inlet 6 does not have a sealing ring 3 11. The stepped inner hole 4a of the opening and closing part 4 is not larger at the front and smaller at the back. The flow channel 2 6a does not directly penetrate the rear end of the water inlet 6. The center of the front end of the water inlet 5 does not have a guide part 5f. Instead, the stepped inner hole 4a is smaller at the front and larger at the back, and the flow channel 5a directly penetrates the front end of the water inlet body 5. The rear end of the water passage body 6 is provided with a water inlet and a sealing ring 4 is fitted and fixed. 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 part 4. The sealing ring 4 abuts against the front hole wall of the stepped inner hole 4a of the opening and closing part 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 passage 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 part 4 to slide forward. The positions of the water inlet 5 and the water passage 6 are fixed. As the opening and closing part 4 slides forward, the sealing ring 4 and the water outlet 5b will be located in the rear part of the stepped inner hole 4a. At this time, the sealing ring 4 no longer forms a seal and loses its function of blocking water. In this way, the water from the water inlet 5 can flow smoothly into the water passage 6 through the water inlet. Furthermore, a sealing ring five is also fitted and fixed to the rear end side of the water inlet 6. The sealing ring five is located in front of the water inlet and abuts against the front hole wall of the stepped inner hole 4a to form a seal. The seal at the sealing ring five is to prevent water coming out of the water inlet 5 from leaking directly out of the gap between the rear end of the water inlet 6 and the opening and closing element 4. A sealing ring six is ​​fitted and fixed to the front end side of the water inlet 5. The sealing ring six abuts against the rear hole wall of the stepped inner hole 4a to form a seal. The seal at the sealing ring six is ​​to prevent water coming out of the water inlet 5 from leaking directly out of the gap between the front end of the water inlet 5 and the opening and closing element 4.
