Description

Technical Field

[0001] This utility model belongs to the technical field of bathroom products, and specifically relates to an electric shower head. Background Technology

[0002] Early showerheads were primarily mechanical, focusing on water conservation and adjusting water flow modes, resulting in relatively simple functions. With technological advancements, electric showerheads, incorporating electric drive systems, not only achieved active pressurization but also intelligent temperature control through controllers and sensors. However, existing electric showerheads use adhesive to fix the temperature sensor. During the application process, uncured adhesive can easily flow along the sensor leads, enveloping or partially adhering to the sensor probe. This reduces the contact area between the probe and the water, affecting temperature measurement accuracy. During use, especially in winter, the significant temperature difference between the water and the showerhead causes intense thermal expansion and contraction of the adhesive, leading to seal failure. Water then enters the sensor leads through the adhesive gaps, causing sensor malfunction.

[0003] Therefore, there is an urgent need for an electric shower head that can measure temperature more accurately, is unaffected by temperature differences, and has better sealing performance. Utility Model Content

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example 1: In this embodiment, an electric shower head, such as Figure 1 and Figure 2 As shown, the shower head body 1 and a temperature measuring device are included. The front of the shower head body 1 is provided with a spray head assembly and the back is provided with a control assembly. The temperature measuring device is disposed inside the shower head body 1. Specifically, the temperature measuring device includes a fixed tube 2, a sealing head 3 and a temperature sensor 4. One end of the fixed tube 2 is fixedly connected to and passes through the front wall of the shower head body 1 and communicates with the spray head assembly. The sealing head 3 seals and covers the other end of the fixed tube 2, so that the internal space of the fixed tube 2 can communicate with the spray head assembly. Water from the spray head assembly can fill the fixed tube 2. The lead wire of the temperature sensor 4 is sealed and passed through the sealing head 3. The probe 6 of the temperature sensor 4 is suspended inside the fixed tube 2 through the lead wire.

[0023] With this structure, during use, some water from the above-mentioned nozzle assembly will enter and fill the above-mentioned fixing tube 2, and the sensor probe 6 will be completely immersed in the water in the above-mentioned fixing tube 2, so the measured temperature is more accurate. The above-mentioned sealing head 3 is used to seal the other end of the above-mentioned fixing tube 2 and fix the lead wire of the temperature sensor 4, so water will not seep into the above-mentioned shower body 1. The method of fixing with glue is completely eliminated, and the seal will not fail due to temperature difference, making the utility model more practical.

[0024] As one specific implementation method of this embodiment, such as Figure 3 and Figure 5 As shown, the sealing head 3 includes an integrally connected end cap 7 and insert plate 8. The end cap 7 is detachably fitted onto the fixed tube 2 by fasteners, or it can be fixed onto the fixed tube 2 by internal and external thread connection. A soft rubber column 5 is fixedly connected to one side of the insert plate 8. The soft rubber column 5 and the insert plate 8 together form a columnar component, so that the insert plate 8 and the soft rubber column 5 are inserted into the fixed tube 2 with an interference fit. The lead wire of the temperature sensor 4 passes through the soft rubber column 5. The soft rubber column 5 cooperates with the insert plate 8 and forms a radial compression with the inner wall of the fixed tube 2 with an interference fit, thereby fixing the lead wire passing through the soft rubber column 5 and making the lead wire securely fixed.

[0025] In this embodiment, as Figure 1 and Figure 2As shown, the above-mentioned shower head assembly includes a shower head mesh plate 9, a limiting ring 10, and a sealing ring 11. An annular wall 12 extends from the front wall of the shower head body 1. The limiting ring 10 is detachably screwed onto the annular wall 12 via internal and external threads, thus pressing the shower head mesh plate tightly against the annular wall 12. This allows the shower head mesh plate 9, the annular wall 12, and the front wall of the shower head body 1 to collectively form a water collection cavity 13. The incoming water first fills the water collection cavity 13, and then flows through the shower head... The water sprays out through the mesh holes on the spray plate 9. The sealing ring 11 is encircled in the water collection chamber 13 and is squeezed by the limiting ring 10 to prevent water from overflowing from the gap between the limiting ring 10 and the annular wall 12. The water collection chamber 13 is connected to the fixed pipe 2. Water enters and fills the fixed pipe 2, so that the probe 6 of the temperature sensor 4 can monitor the real-time temperature of the shower head spray end at all times. The temperature measurement is closer to the user's body temperature rather than the water temperature in the internal pipes of the shower head.

[0026] Furthermore, such as Figures 1 to 3 As shown, the shower head body 1 is also equipped with a water pump 14, preferably a micro diaphragm pump. The water pump 14 is electrically connected to the control component. The water inlet end of the water pump 14 is connected to a water inlet connector 15, and the water outlet end of the water pump 14 is connected to a water outlet connector 16. The front wall of the shower head body 1 is provided with a water inlet hole 35 that communicates with the water collection chamber 13. A connecting pipe 17 extends from the end of the water inlet hole 35 away from the water collection chamber 13. The water outlet end of the water outlet connector 16 is inserted into the connecting pipe 17. The water outlet connector 16 and the connecting pipe 17 are interference-fitted to ensure that water does not overflow into the shower head body 1.

[0027] As an optimization, such as Figure 3 As shown, both the inlet connector 15 and the outlet connector 16 are L-shaped pipes, preferably made of rubber or silicone. The L-shaped structure allows the water to be buffered when entering and exiting the water pump 14, preventing excessive instantaneous water pressure that could prevent the shower head screen 9 from spraying water in time, thus causing the diaphragm or rubber cup inside the diaphragm pump to tear. The outlet end of the outlet connector 16 is provided with an annular pressure plate 18, which facilitates the use of corresponding assembly tools to press against the annular pressure plate 18, thereby pressing down the inlet connector 15, making the inlet connector 15 fit more tightly with the connecting pipe 17, and improving the sealing effect through mutual squeezing.

[0028] Furthermore, such as Figure 1 As shown, it also includes a shock-absorbing rubber pad 19, which is arranged in a ring between the water pump 14 and the inner wall of the shower body 1. The shock-absorbing rubber pad 19 prevents the water pump 14 from directly contacting the shower body 1, and plays the role of shock absorption, vibration prevention and noise reduction, thereby improving the user experience.

[0029] According to a preferred embodiment, such as Figure 1 and Figure 2 As shown, the back of the shower head body 1 is detachably covered with a rear cover 20, meaning the back of the shower head body 1 is open and closed by the rear cover 20. The rear cover 20 can be detachably fixed to the shower head body 1 by means of internal or external threads or snap-fit ​​connection. The rear cover 20 has a mounting slot 21, specifically a rectangular slot. The control components are installed in the mounting slot 21. Specifically, the control components include a control board 22, a switch button 23, and a light shield 24. The control board 22 is a circuit board, and the light shield 24 is embedded in the mounting slot 21. The control board 22 is fixed to the light shield. The control plate 22 is located on the side opposite to the back cover 20. A sealant layer is provided on the surface of the control plate 22. The sealant layer completely wraps the control plate 22 and seals the position where the control plate 22 meets the switch button 23 and the light shield 24, thereby improving the sealing performance and preventing water from entering the control plate 22. The sealant layer is preferably transparent epoxy resin, polyurethane, or conformal coating. The light shield 24 is provided with a central hole 25. One end of the switch button 23 is disposed on the control plate 22, and the other end of the switch button 23 extends out of the back cover 20 through the central hole 25 and the mounting slot 21.

[0030] Furthermore, it also includes a fixing plate 34, which covers one side of the circuit board and is detachably and securely connected to the rear cover 20 by fasteners, thereby firmly fixing the circuit board and the light shield 24 to the rear cover 20 to prevent them from falling off or shifting.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, it also includes a light-transmitting ring plate 26. The rear cover 20 has a countersunk hole 27 on the side opposite to the control plate 22. The light-transmitting ring plate 26 is embedded in the rear cover 20 through the countersunk hole 27. The light-transmitting ring plate 26 is used to digitally display information such as temperature.

[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 6As shown, it also includes a handle 28, a Z-shaped guide tube 29, and a bottom cover 30. The top of the handle 28 is connected to the shower body 1. The bottom cover 30 is detachably connected to the bottom of the handle 28. The bottom of the bottom cover 30 is provided with an annular plug 31. The annular plug 31 is adapted to a universal pipe in the bathroom field. The universal pipe can be sealed and inserted into the annular plug 31. The bottom end of the Z-shaped guide tube 29 passes through the bottom cover 30 and extends into the annular plug 31, thereby connecting the universal pipe and the Z-shaped guide tube 29. The top of the Z-shaped guide tube 29 is connected to the water inlet connector 15 through a water pipe 33, so that the incoming water enters the water pump 14 for pressurization through the Z-shaped guide tube 29, the water pipe 33, and the water inlet connector 15. The connection position of the water pipe 33 and the water inlet connector 15 is set in a U-shape so that the incoming water can be buffered.

[0033] In this embodiment, as Figure 1 As shown, it also includes a battery pack 32, which is fixed inside the handle 28. The battery pack 32 is a silicone protective cover, independently sealed, and contains multiple batteries connected in series to prevent water ingress. Using a silicone protective cover to seal the battery is existing technology in the field of bathroom products, and the structure will not be described again. The battery pack 32 is fixed to one side inside the handle 28, and the other side passes through the water pipe 33. The Z-shaped guide tube 29 allows the water pipe 33 to give way to the battery pack 32, without taking up space, making fuller use of space, thereby accommodating more batteries and increasing the battery life.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
