Description

Technical Field

[0001] This utility model belongs to the field of shower technology, and specifically refers to a handwheel with light and a shower. Background Technology

[0002] Shower units are common in modern home bathrooms. They are used to mix hot and cold water from the pipes and then distribute the water to different water paths to supply water to water-using devices such as overhead showers, hand showers, and aerators, ultimately enabling functions such as showering, washing, and storage.

[0003] Shower units typically have a handwheel as the main switch. The handwheel is connected to a switching valve core inside the valve body, allowing the user to control the flow of water between the water supply end (i.e., the water pipes embedded in the wall) and the water usage end by turning the handwheel. In addition, the valve body also has several switching valve cores corresponding to each water-using device, used to independently control the on / off state of each device.

[0004] In practical applications, when a shower is not in use, the main switch (i.e., the handwheel) should generally be switched to the off position to prevent pressure buildup inside the valve body, which can lead to leaks, shortened lifespan, and other adverse consequences. However, existing handwheels are generally cylindrical, making it difficult for users to visually identify their position. This can cause users to forget to turn off the main switch after using the shower, thus affecting the shower's lifespan. Utility Model Content

[0005] The main purpose of this utility model is to provide a handwheel and shower with light, to solve the problems existing in the prior art, so that the handwheel has a light indication function and can be used to indicate the on / off status of the handwheel.

[0006] To achieve the above objectives, one of the solutions of this utility model is: A handwheel with a light includes a handwheel body, a light guide, a mounting cover, and a light ring. The handwheel body includes a rotating part with a plurality of grooves recessed on its circumferential surface. The light guide includes a light ring fitted to the end face of the rotating part and a plurality of light guide pillars perpendicularly connected to one end face of the light ring. The light guide pillars are inserted into the rotating part and protrude from the grooves. The mounting cover is mounted on the other end face of the light ring and forms a sealed first chamber. The light ring is disposed in the first chamber and contains a plurality of LEDs. The light emitted by the LEDs is emitted through the light ring and light guide pillars of the light guide and then leaks out of the handwheel body.

[0007] The handwheel body also includes a connecting part, which is coaxially connected to the end of the rotating part, and the circumferential surfaces of the two form an annular step for the light guide ring to fit against; the connecting part passes through the mounting cover, and the inner wall and end wall of the mounting cover are respectively sealed to the circumferential surface of the connecting part and the end face of the light guide ring.

[0008] Preferably, the handwheel further includes a circuit board and at least one battery; a second chamber is provided in the connecting part, and the second chamber is provided with a through hole communicating with the first chamber; the circuit board and the battery are both disposed in the second chamber; the circuit board is electrically connected to the lamp ring and the battery respectively.

[0009] Preferably, the handwheel further includes a battery bracket disposed in the second chamber, the battery bracket being used to fix the battery and electrically connected to the circuit board.

[0010] Preferably, the handwheel further includes an end cap; the circuit board is designed in annular shape; the outer end of the second chamber extends to the end face of the rotating part away from the light guide ring, and its inner end is provided with a positioning post for the circuit board to be fitted; the end cap is threadedly fitted to the outer end of the second chamber and pushes the battery holder against the end face of the positioning post.

[0011] Preferably, a sealing ring is provided between the circumferential surface of the end cap and the inner wall of the second chamber; a slotted groove is provided on the outer end face of the end cap.

[0012] Preferably, the handwheel further includes a fixing cover; the length of the light guide post is greater than the length of the groove, and the end of the light guide post away from the light guide ring protrudes from the end face of the groove; the fixing cover covers the circumferential and end faces of all the light guide posts and is axially limited by the end cover; the rotating part, the light guide ring, the mounting cover and the fixing cover are coaxially arranged and have the same outer diameter.

[0013] The bottom wall of the groove is provided with a light guide groove that is parallel to and connected to the groove. The end of the light guide groove extends to the end face of the rotating part, and the light guide post is inserted into the rotating part through the end of the light guide groove.

[0014] The second solution of this utility model is: A shower unit includes a handwheel with a light, a shower unit housing, a valve body, and a switching valve core; the valve body is installed inside the shower unit housing, and the switching valve core is installed inside the valve body for controlling the on / off water flow and water circuit switching functions of the valve body; the handwheel body is connected to the valve stem of the switching valve core through its connecting part.

[0015] The shower also includes a magnetic component fixed to the switching valve core housing; a Hall switch that wirelessly senses and cooperates with the magnetic component is provided on the circuit board inside the handwheel for controlling the light ring; a fixing ring is installed on the circumference of the switching valve core exposed on the valve body, and the magnetic component is embedded in a mounting post on the fixing ring.

[0016] After adopting the above technical solution, the present invention has the following technical effects: (1) This utility model installs a light guide on the end face of the rotating part of the handwheel body. The light guide has a light guide ring coaxial with the rotating part and a light guide column inserted into the rotating part and exposed in the groove. This allows the light emitted by the lamp ring installed in the mounting cover to be simultaneously emitted through the light guide ring and several light guide columns, so that the end face and the circumference of the rotating part can both emit light. The light emission area is large and easy to observe. Thus, it can be used in conjunction with mechanical linkage, wireless linkage and other methods to link the switch of the lamp ring with the device or mechanism controlled by the handwheel, so as to indicate the switch status of the handwheel and prevent the user from forgetting to turn off the handwheel after using the shower.

[0017] (2) The groove on the circumference of the rotating part can also serve as its anti-slip design, making it less likely for users to slip when turning the rotating part, resulting in a better operating experience. In other words, this utility model utilizes the anti-slip texture design of the traditional handwheel for installing the light guide column, achieving the goal of saving design space, and the size of the handwheel will not become larger as a result.

[0018] (3) The handwheel of this utility model has both the original knob function and the additional light-emitting function. It can be designed as an independent functional module by the manufacturer as a standard part and used to adapt to different products, such as a switch for showers, faucets, etc. Attached Figure Description

Detailed Implementation

[0029] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0030] refer to Figures 1 to 6 As shown, this is the first embodiment of the present invention, which discloses a handwheel 100 with a light, including a handwheel body 101, a light guide 102, a mounting cover 103 and a light ring 104; The handwheel body 101 includes a rotating part 101a for the user to turn, and the circumferential surface of the rotating part 101a is recessed to form a plurality of grooves 1011. The light guide 102 includes a light guide ring 1021 coaxially attached to the end face of the rotating part 101a, and a plurality of light guide pillars 1022 vertically connected to one end face of the light guide ring 1021. The number of light guide pillars 1022 corresponds to the number of grooves 1011. The light guide pillars 1022 are inserted into the rotating part 101a and exposed in the grooves 1011. The mounting cover 103 is coaxially mounted on the other end face of the light guide ring 1021 and forms a sealed first chamber 1031; The lamp ring 104 is disposed in the first chamber 1031 and is provided with a number of lamp beads 1041. The light emitted by the lamp beads 1041 is exposed to the handwheel body 101 through the light guide ring 1021 and light guide column 1022 of the light guide member 102.

[0031] Through the above solution, this utility model installs a light guide 102 on the end face of the rotating part 101a of the handwheel body 101. The light guide 102 has a light guide ring 1021 coaxial with the rotating part 101a and a light guide column 1022 inserted into the rotating part 101a and exposed in the groove 1011. This allows the light emitted by the lamp ring 104 installed in the mounting cover 103 to be simultaneously guided out through the light guide ring 1021 and several light guide columns 1022, so that both the end face and the circumference of the rotating part 101a can "illuminate", and the illuminated area is large and easy to observe. Thus, it can be used in conjunction with mechanical linkage, wireless linkage, etc., to link the switch of the lamp ring 104 with the device or mechanism (such as the valve core of a shower) controlled by the handwheel 100. The light guide column 1022 is used to indicate the on / off status of the handwheel 100, preventing users from forgetting to turn it off after using the shower. Simultaneously, the groove 1011 on the circumference of the rotating part 101a also serves as an anti-slip design, preventing slippage when turning the rotating part 101a and improving the operating experience. In other words, this invention utilizes the anti-slip texture design of traditional handwheels to install the light guide column 1022, achieving the goal of saving design space without increasing the size of the handwheel 100. The handwheel 100 of this invention combines the original knob function with the added light-emitting function, and can be designed as an independent functional module by the manufacturer as a standard part for adaptation to different products, such as showerheads and faucets. Furthermore, a handwheel with lighting is more aesthetically pleasing, stimulating customers' purchasing desire and possessing good market prospects.

[0032] The following shows the structural details of the first embodiment.

[0033] See Figure 4 , Figure 5 The handwheel body 101 also includes a connecting part 101b for mounting the handwheel 100. The connecting part 101b can connect one end of the handwheel 100 to the switching valve core of a bathroom appliance such as a shower or faucet. The connecting part 101b is coaxially connected to the end of the rotating part 101a, and the circumferential surfaces of the two form an annular step 1012 for the light guide ring 1021 to fit against. The connecting part 101b passes through the mounting cover 103, and the inner wall and end wall of the mounting cover 103 are respectively sealed to the circumferential surface of the connecting part 101b and the end face of the light guide ring 1021 by means of sealant bonding, ultrasonic welding, etc. This prevents water from entering the first chamber 1031.

[0034] Furthermore, the handwheel 100 also includes a circuit board 105 and at least one battery 106; a second chamber 1013 is provided inside the connecting part 101b, and the second chamber 1013 is provided with a through hole 1014 communicating with the first chamber 1031; the circuit board 105 and the battery 106 are both disposed in the second chamber 1013; the circuit board 105 is electrically connected to the lamp ring 104 and the battery 106 respectively, and the through hole 1014 is used for the wires connecting the circuit board 105 and the lamp ring 104 to pass through. Thus, by utilizing the internal space of the handwheel 100 to install the circuit board 105 controlling the lamp ring 104 and the battery 106 supplying power, both electrical safety and the external size of the handwheel 100 are ensured, and the handwheel with lights also achieves independent power supply and control functions.

[0035] Secondly, the aforementioned handwheel 100 also includes a battery bracket 107 disposed in the second chamber 1013. The battery bracket 107 is used to simultaneously fix multiple batteries 106 and is electrically connected to the circuit board 105. For example, it may be provided with conductive plates and / or conductive springs for the ends of the batteries 106 to abut against. Each conductive plate / conductive spring is finally connected to the circuit board 105 through a wire.

[0036] Furthermore, the aforementioned handwheel 100 also includes an end cap 108; the circuit board 105 is designed in a ring shape; the outer end of the second chamber 1013 extends to the end face of the rotating part 101a away from the light guide ring 1021, and its inner end is provided with a positioning post 1015 for the circuit board 105 to be fitted; the end cap 108 is threadedly fitted to the outer end of the second chamber 1013 and pushes the battery holder 107 against the end face of the positioning post 1015, thereby fixing the battery holder 107 and sealing the second chamber 1013 to prevent moisture from entering the second chamber 1013 and ensure electrical safety. A sealing ring 109 is provided between the circumferential surface of the end cap 108 and the inner wall of the second chamber 1013; the outer end face of the end cap 108 is provided with a slotted groove 1081, which can be turned and opened with tools for easy inspection or replacement of the battery 106.

[0037] Finally, the handwheel 100 also includes a fixing cover 110; the length of the light guide post 1022 is greater than the length of the groove 1011, so that the end of the light guide post 1022 away from the light guide ring 1021 protrudes from the end face of the groove 1011; the fixing cover 110 covers the circumferential and end faces of all the light guide posts 1022 and is axially limited by the end cover 108, that is, it is fixed by the end cover 108 and will not shake. Thus, the ends of all the light guide posts 1022 can also be fixed. Among them, the outer diameters of the rotating part 101a, the light guide ring 1021, the mounting cover 103 and the fixing cover 110 are equal, so that the outer circumferential surfaces of the three are flush and there are no unevenness, so that they are not easy to bump or scratch the user during use; the circumferential surface of the end cover 108 and the inner wall of the fixing cover 110 are axially limited by a pair of annular flanges.

[0038] The bottom wall of the groove 1011 is provided with a light guide groove 1016 that is parallel to and connected to the groove 1011. The end of the light guide groove 1016 extends to the end face of the rotating part 101a. The light guide post 1022 is inserted into the rotating part 101a through the end of the light guide groove 1016.

[0039] The aforementioned grooves 1011 are arranged at equal angular intervals around the axis of the handwheel 100. This ensures that the grooves 1011 are evenly distributed on the circumference of the handwheel 100, optimizing the grip feel and achieving uniform light emission from the circumference of the handwheel 100, resulting in a more comfortable visual effect.

[0040] The lamp beads 1041 on the lamp ring 104 are arranged one-to-one with each light guide post 1022.

[0041] The light guide 102 mentioned above can be made of materials such as acrylic that have light guiding and light transmission properties.

[0042] refer to Figures 7 to 9 As shown, this is the second embodiment of the present invention, which discloses a shower, including the aforementioned handwheel 100 with light, as well as a shower housing 200, a valve body 300, and a switching valve core 400; the valve body 300 is installed inside the shower housing 200, and the switching valve core 400 is installed inside the valve body 300, used to control the valve body 300's functions of switching water flow and water circuit switching; the handwheel body 101 of the handwheel 100 is connected to the valve stem 401 of the switching valve core 400 through its connecting part 101b.

[0043] With the above solution, the shower can have a handwheel 100 with a light and all the technical effects of the handwheel 100.

[0044] The following shows the structural details of the second embodiment.

[0045] In practical applications, the switching of the lamp ring 104 can be controlled by wireless sensing and mechanical linkage. Taking wireless sensing as an example, the second embodiment also includes a magnetic element 500 fixed on the housing of the switching valve core 400; a Hall switch 1051 that cooperates with the magnetic element 500 for wireless sensing is provided on the circuit board 105 inside the handwheel 100 for controlling the lamp ring 104. Therefore, the Hall switch 1051 can work in conjunction with the wireless sensor of the magnetic element 500 to "sensor" the switch position of the handwheel 100 and control the switch state of the lamp ring 104. For example, when the handwheel 100 rotates the valve stem 401 to open the main switch, the Hall switch 1051 and the handwheel 100 rotate synchronously to make the magnetic element 500 move out of the sensing range of the Hall switch 1051, defining it as the "open position". At this time, the lamp ring 104 can be designed to be powered on, and the light guide 102 will emit light to inform the user that the shower is currently in the "open state". If the user forgets to turn off the handwheel 100 after using the shower, the light will remind them. Conversely, when the handwheel 100 rotates the valve stem 401 to close the main switch, the magnetic element 500 enters the sensing range of the Hall switch 1051, defining it as the "closed position". At this time, the lamp ring 104 can be designed to be de-powered, and the handwheel 100 will no longer light up, informing the user that the shower is currently in the "closed state". In addition to designs with magnetic elements and Hall switches, the sensing design between the handwheel 100 and the switching valve core 400 can also be a magnetic element and reed switch, infrared sensing, photoelectric sensing, mechanical contact, etc.

[0046] Furthermore, a retaining ring 600 is mounted on the circumferential surface of the valve body 300 exposed above the switching valve core 400. A magnetic component 500 is embedded within a mounting post 601 on the retaining ring 600. The retaining ring 600 and the circumferential surface of the switching valve core 400 are engaged by convex teeth to prevent rotation. The mounting of the retaining ring 600 is achieved using conventionally designed convex teeth on the circumferential surface of the switching valve core 400. The mounting post 601 can be used to indicate the installation position and angle of the magnetic component 500 during component assembly, facilitating quick identification.

[0047] The end face of the connecting part 101b is provided with a keyway 1017 for the valve stem 401 to be inserted. This allows for a coaxial connection between the connecting part 101b and the valve stem 401, enabling the valve stem 401 to rotate synchronously when the handwheel 100 is turned. The valve stem 401 and the keyway 1017 can be locked together using screws on the end face or side of the valve stem 401 for relative fixation.

[0048] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
