Description

Technical Field

[0001] This utility model relates to the field of bathroom accessories, specifically to a water flow temperature measuring switch device. Background Technology

[0002] Existing shower faucets generally have a digital temperature display function. They generate electricity and detect water temperature by installing a hydroelectric generator with a temperature sensor. When the shower faucet is turned on, the water flow washes the impeller of the hydroelectric generator, and the electricity is used to power the temperature sensor, external display screen, and light strip. Since this type of hydroelectric generator relies on water flow for operation, it is easy for the hydroelectric generator to generate too little electricity under low water flow conditions, which will cause the display screen or light strip to flicker, affecting the user experience. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a water flow temperature measuring switch device that can be opened according to water flow control, detect water temperature, and achieve stable power supply at the same time.

[0004] To address the above problems, the following technical solution is provided: a water flow temperature measuring switch device, comprising a housing with mounting threads, the housing including a first cavity and a second cavity separated from the first cavity, the first cavity being provided with a power storage module and an external connecting cable; an impeller is provided in the second cavity, the second cavity having a first water inlet and a second water inlet, water flowing through the first water inlet to the second water inlet or through the second water inlet to the first water inlet scouring and driving the impeller to perform angular motion; the impeller is provided with a magnetic component, the housing is provided with a magnetic control switch, the impeller controlling the magnetic control switch to open or close through the angular motion of the magnetic component; the housing is also provided with a temperature measuring head for detecting the water flow temperature in the second cavity.

[0005] The present invention is further provided with a limiting mechanism for limiting the rotation angle range of the impeller and a reset mechanism for resetting the impeller after it makes angular movement, between the second cavity and the impeller.

[0006] The present invention is further configured such that the limiting mechanism includes a positioning protrusion located on the inner wall of the second cavity and a swing groove opened in a fan shape on the impeller, wherein the positioning protrusion moves in the swing groove when the impeller makes angular movement.

[0007] The present invention is further configured such that the reset mechanism includes a reset member located on the side wall of the second cavity, the reset member being adapted to a magnetic member, and the impeller being reset by magnetic attraction or repulsion after the water flow stops rinsing; or the reset mechanism is a torsion spring mounted on the angular axis of motion of the impeller.

[0008] The present invention is further configured such that the magnetic component includes a first magnetic body and a second magnetic body, the first magnetic body and the second magnetic body being arranged along the circumferential direction of the impeller; the first magnetic body cooperates with a magnetic control switch to control the on / off state, and the second magnetic body and the reset component are magnetically attracted or repelled to achieve reset.

[0009] The present invention is further configured such that the first cavity is provided with a temperature measuring hole connected to the second cavity, and the temperature measuring head reaches the second cavity from the first cavity through the temperature measuring hole; the first cavity is provided with a magnetic control groove opened into the interlayer of the side wall of the second cavity, and the magnetic control switch is located in the magnetic control groove.

[0010] The present invention is further configured to include a charging port, which is connected to the energy storage module via an external cable or installed at the opening of the first cavity.

[0011] The present invention is further configured such that the magnetic control switch and / or the temperature measuring head is led out through an external cable and is provided with a connecting plug.

[0012] The present invention is further configured such that the first cavity is filled with sealant / resin.

[0013] The present invention is further configured such that the first water inlet is located on the side wall of the second cavity, the second water inlet is located at the end of the second cavity, and there are multiple first water inlets, which are arranged at intervals along the circumferential direction of the second cavity and are inclined in the tangential direction of the inner circle of the second cavity or the rotational contour of the impeller; or the second water inlet is located on the side wall of the second cavity, the first water inlet is located at the end of the second cavity, and there are multiple first water inlets, which are arranged at intervals along the circumferential direction of the second cavity and are spirally inclined.

[0014] The beneficial effects of this utility model are: 1. This device is used to replace conventional hydroelectric generators. The energy storage module is a rechargeable lithium-ion battery that can provide a stable and reliable power output. When water flows through the impeller, it causes the impeller to rotate, which moves the magnetic component closer to or away from the magnetic control switch to detect whether water is flowing through. This controls the energy storage module to supply power, which in turn drives the temperature sensor and transmits the temperature information to the display screen via an external cable. Alternatively, it can illuminate the LED strip. Since the impeller is only used to detect the presence of water flow and not to generate electricity, the stable power supply from the energy storage module effectively solves the problem of the display screen and LED strip flickering due to insufficient power generation of the hydroelectric generator when the water flow is small. 2. The impeller only needs to rotate within a certain angle to trigger the magnetic control switch to open or close via the magnetic components. Therefore, the limit mechanism is used for limiting, while the reset mechanism resets the impeller in time when the water flow stops, thereby controlling the energy storage module to stop supplying power to the outside. 3. The first magnetic body uses magnetism to control the magnetic switch; the second magnetic body uses magnetism to adapt to the reset component and provide the force required to reset the impeller; 4. The temperature measuring head reaching the second chamber effectively improves temperature measurement accuracy; the magnetic switch being located inside the magnetic control groove effectively ensures sealing. 5. The charging port is preferably Type-C, so that the battery module can be charged when its power is low; 6. Water flows in through the first inlet and out through the second inlet. The inclined or spiral inclined design can increase the impact force of the water flow on the impeller, so that the impeller can still rotate under low water flow conditions.

Detailed Implementation

[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0029] refer to Figures 1 to 12 ,like Figures 1 to 12 The water flow temperature measuring switch device shown includes a housing 10 with mounting threads 15. The housing 10 includes a first cavity 11 and a second cavity 12 separated from the first cavity 11. The first cavity 11 is provided with a power storage module 20 and an external connecting cable 30. An impeller 40 is provided in the second cavity 12. The second cavity 12 has a first water inlet 121 and a second water inlet 122. When water flows through the first water inlet 121 to the second water inlet 122 or through the second water inlet 122 to the first water inlet 121, it washes and drives the impeller 40 to make angular movements. The impeller 40 is provided with a magnetic element 41. The housing 10 is provided with a magnetic control switch 50. The angular movement of the impeller 40 causes the magnetic element 41 to control the on / off state of the magnetic control switch 50. The housing 10 is also provided with a temperature measuring head 60 for detecting the temperature of the water flow in the second cavity 12.

[0030] In the above structure, the device is used to replace a conventional hydroelectric generator; the energy storage module 20 is a rechargeable lithium-ion battery that can provide a stable and reliable power output; when water flows through the impeller 40, it causes the impeller 40 to rotate, causing the magnetic component 41 to move closer to or away from the magnetic control switch 50, thereby detecting whether water is flowing through, and thus controlling the energy storage module 20 to supply power to the outside. While supplying power to the outside, it drives the temperature sensor 60 to work and transmits the temperature information to the display screen (not shown in the figure) through the external cable 30, or, based on this, lights up the light strip (not shown in the figure); since the impeller 40 is only used to detect the presence or absence of water flow, rather than generating electricity, under the stable power supply of the energy storage module 20, the problem of the display screen and light strip flickering due to insufficient power generation of the hydroelectric generator when the water flow is small is effectively solved.

[0031] In this embodiment, a limiting mechanism for limiting the rotation angle range of the impeller 40 and a reset mechanism for resetting the impeller 40 after it makes angular movement are provided between the second cavity 12 and the impeller 40.

[0032] In the above structure, the impeller 40 only needs to rotate within a certain angle to trigger the magnetic control switch 50 to open or close through the magnetic component 41. Therefore, the limit mechanism is used for limiting, while the reset mechanism resets the impeller 40 in time when the water flow stops, thereby controlling the energy storage module 20 to stop supplying power to the outside.

[0033] In this embodiment, the limiting mechanism includes a positioning protrusion 123 located on the inner wall of the second cavity 12 and a swing groove 42 opened in a fan shape on the impeller 40. When the impeller 40 moves in an angular direction, the positioning protrusion 123 moves in the swing groove 42.

[0034] In the above structure, the positions of the positioning protrusion 123 and the swing groove 42 can be interchanged.

[0035] In this embodiment, the reset mechanism includes a reset member 70 located on the side wall of the second cavity 12. The reset member 70 is adapted to the magnetic member 41 and resets the impeller 40 by magnetic attraction or repulsion after the water flow stops rinsing; or the reset mechanism is a torsion spring (not shown in the figure) mounted on the angular movement axis of the impeller 40.

[0036] In the above structure, a reverse reset force is provided for the impeller 40.

[0037] In this embodiment, the magnetic component 41 includes a first magnetic body 411 and a second magnetic body 412, which are arranged along the circumferential direction of the impeller 40. The first magnetic body 411 cooperates with the magnetic control switch 50 to control the on and off states, and the second magnetic body 412 is magnetically attracted or repelled by the reset component 70 to achieve reset.

[0038] In the above structure, the first magnetic body 411 uses magnetism to control the magnetic switch 50; the second magnetic body 412 uses magnetism to adapt to the reset member 70 to provide the force required to reset the impeller 40.

[0039] In this embodiment, the first cavity 11 is provided with a temperature measuring hole 13 connected to the second cavity 12, and the temperature measuring head 60 reaches the second cavity 12 from the first cavity 11 through the temperature measuring hole 13; the first cavity 11 is provided with a magnetic control groove 14 opened into the interlayer of the side wall of the second cavity 12, and the magnetic control switch 50 is located in the magnetic control groove 14.

[0040] In the above structure, the temperature measuring head 60 reaching the second cavity 12 can effectively improve the temperature measurement accuracy; the magnetic control switch 50 located in the magnetic control groove 14 can effectively ensure the sealing performance.

[0041] In this embodiment, a charging port 80 is also included. The charging port 80 is connected to the energy storage module 20 via an external cable 30 or installed at the opening of the first cavity 11.

[0042] In the above structure, the charging port 80 is preferably type-c, which charges the energy storage module 20 when it is low on power.

[0043] In this embodiment, the magnetic switch 50 and / or the temperature measuring head 60 are led out through the external cable 30 and are provided with a connecting plug 31.

[0044] The above structure is used for connecting to an external display screen.

[0045] In this embodiment, the first cavity 11 is filled with sealant / resin.

[0046] The above structure effectively improves sealing performance.

[0047] In this embodiment, the first water inlet 121 is located on the side wall of the second cavity 12, and the second water inlet 122 is located at the end of the second cavity 12. There are multiple first water inlets 121, which are arranged at intervals along the circumferential direction of the second cavity 12 and are inclined in the tangential direction of the inner circle of the second cavity 12 or the rotational contour of the impeller 40; or the second water inlet 122 is located on the side wall of the second cavity 12, and the first water inlet 121 is located at the end of the second cavity 12. There are multiple first water inlets 121, which are arranged at intervals along the circumferential direction of the second cavity 12 and are spirally inclined (not shown in the figure).

[0048] In the above structure, water flows in from the first inlet 121 and flows out through the second inlet 122. The inclined or spiral inclined opening can increase the impact force of the water flow on the impeller 40, so that the impeller 40 can still rotate under small water flow conditions.

[0049] In this embodiment, the outer wall of the second cavity 12 is fitted with a cylindrical filter screen 90 for providing filtration to the first water outlet 121.

[0050] In the above structure, foreign objects in the water are prevented from entering the second cavity 12.

[0051] In this embodiment, a water passage end cap 91 is provided at the end of the second cavity 12, and the first water passage 121 is located on the water passage end cap 91 when the first water passage 121 is located at the end of the second cavity 12.

[0053] In this embodiment, a sealing ring 92 is provided at the end of the mounting thread 15 away from the second cavity 12.
