Description

Technical Field

[0001] This invention relates to a shower system accessory, specifically, to a showerhead. Furthermore, this invention also relates to a shower system. Background Technology

[0002] In some devices or equipment used in humid environments, it is very difficult to power some of their electrical components (such as displays). They not only need to be protected from moisture, but also need to be installed and disassembled frequently for maintenance due to the environmental conditions.

[0003] For example, with the advent of the smart era, terminal showers have also begun to add electronic control components. However, since the shower is installed below the shower head and the environment is often wet and humid, the waterproof requirements for the shower have become very high.

[0004] Therefore, designing and waterproofing the power supply for the shower unit has become a technical challenge. In particular, because these shower units involve personal safety, they generally require DC power batteries. However, the battery capacity of such batteries is limited, requiring frequent maintenance. Designing a convenient, quick, and easy-to-install / disassemble installation structure is also a challenge.

[0005] Therefore, a completely new shower unit that is easy to install and disassemble and suitable for use in humid environments needs to be designed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a shower device whose battery box assembly can be conveniently and quickly installed and disassembled in small and humid environments such as shower rooms, and facilitates battery maintenance.

[0007] The technical problem to be solved by the present invention is to provide a shower that not only enables quick and convenient installation and disassembly of the battery box assembly, but also effectively seals and prevents moisture from the power supply part of the shower in the humid environment of the shower room, thereby reliably supplying power to the electrical components of the shower.

[0008] In addition, the technical problem to be solved by the present invention is to provide a shower system in which the power supply device of the shower is easy to install and disassemble, and easy to replace and maintain.

[0009] To solve the above-mentioned technical problems, the present invention provides a shower, wherein the shower includes a mounting base with a mounting chamber, and a battery box assembly is installed in the mounting chamber. The outer surface of the side wall of the battery box housing of the battery box assembly is provided with a housing snap-fit ​​track groove structure. The housing snap-fit ​​track groove structure includes a track groove formed on the side wall of the battery box housing and not penetrating the thickness of the side wall. The track groove is structured to cooperate with the sliding locking member of the housing snap-fit ​​track groove structure so that the battery box assembly can be installed, inserted, removed, and locked in place.

[0010] Preferably, the track groove includes a through end that passes through the insertion end face of the battery box assembly, a closed end opposite to the through end, two side walls of the groove, and a bottom wall of the groove. An insertion track, a locking groove, and a pull-out track are formed in sequence within the track groove. A locking member extension groove is provided on the side wall of the mounting chamber, and the extension end of the sliding locking member extends into the interior of the mounting chamber through the locking member extension groove, so as to cooperate with the track groove so that the battery box assembly can be inserted, removed, and locked in place.

[0011] More preferably, the mounting chamber is provided with an elastic device, a pressure cover, and the battery box assembly sequentially from its closed end to the mounting opening.

[0012] Specifically, the elastic device is a pair of springs, and the pressure cap is provided with a corresponding spring seat to install the spring.

[0013] More preferably, the insertion end of the battery box assembly faces the cover, and a circuit interface groove is formed on the end face of the insertion end, and a sealing element is provided in the circuit interface groove.

[0014] Specifically, the cover is provided with a battery connector, and when the battery box assembly is inserted into place and locked, the battery connector is electrically connected to the battery interface portion housed in the circuit interface slot.

[0015] Specifically, the battery connector on the cover is connected to the electrical components of the shower via wires.

[0016] Preferably, the elastic device presses against the cover, and the cover is pressed against the end face of the insertion end by the elastic force of the elastic device to tighten the seal, thereby forming a seal for the electrical connection between the battery connector and the battery interface.

[0017] Specifically, the battery box assembly encapsulates a battery and a circuit board electrically connected to the battery within its battery box housing. The battery interface portion of the circuit board is accommodated within the circuit interface slot. The battery interface portion includes a charging interface and a discharging interface, and the battery connector is electrically plugged into the discharging interface.

[0018] Preferably, the circuit interface groove is formed on one side of the insertion end face, and a balance sealing groove that does not penetrate the inside of the battery box housing is also formed on the other side of the insertion end face. A balance spare seal is installed in the balance sealing groove so that when the battery box assembly is inserted into place and locked, the cover presses the balance spare seal to keep both sides of the cover stable.

[0019] Preferably, the sliding locking member and the track groove are configured to cooperate as follows: in the battery box assembly insertion state, the insertion end of the battery box assembly can be inserted into the mounting opening and pushed inward, and the extension end of the sliding locking member enters the insertion track from the through end of the track groove, thereby the insertion end pushes the pressure cap to move inward against the elastic force of the elastic device, so that the extension end of the sliding locking member slides relative to the insertion track; in the locked state, the battery box assembly moves to such that the extension end of the sliding locking member enters the locking groove and is locked; and in the pulled-out state, the extension end is guided from the locking groove into the pull-out track, and the battery box assembly is pulled outward under the elastic thrust of the elastic device.

[0020] As a preferred structural form, the housing snap-fit ​​track groove structure includes a track forming part disposed within the track groove. The track forming part divides the internal space of the track groove into an insertion track, a locking groove, and an extraction track that are connected in sequence. The insertion track includes an insertion direction track segment and an insertion turning track segment in sequence. The extraction track includes an extraction turning track segment and an extraction direction track segment in sequence. The locking groove is located between the insertion turning track segment and the extraction turning track segment.

[0021] Furthermore, the track forming portion includes a locking guide tongue having the locking groove and a protruding triangular guide portion protruding from the end wall of the closed end toward the locking guide tongue. The locking guide tongue extends from one side wall of the groove to the other side wall of the groove bottom wall and is inclined toward the closed end. There is a gap between the extended end of the locking guide tongue and the other side wall of the groove for forming the component of the insertion direction track segment. The outer surface of the fixed end of the locking guide tongue is provided with a groove channel for forming the component of the extraction direction track segment. The locking guide tongue and the protruding triangular guide portion are spaced apart from each other, and the locking groove is formed on the side of the locking guide tongue facing the apex of the protruding triangular guide portion.

[0022] Specifically, the protruding triangular guide protrudes from the end wall of the closed end, thereby forming an insertion corner and an extraction corner on both sides of the closed end. The interval between each side of the protruding triangular guide and the locking guide tongue respectively forms the insertion corner track segment and the extraction corner track segment. The insertion direction track segment is connected to the insertion corner track segment through the insertion corner, and the extraction corner track segment is connected to the extraction direction track segment through the extraction corner.

[0023] Particularly preferably, the locking groove is offset from the apex of the protruding triangular guide by being more biased toward the side wall of the groove, thereby forming a misaligned pull-out guide structure at the locking groove. In the pull-out state, the battery box assembly is pushed inward, and the extension end of the sliding locking member is pushed into the pull-out track at the locking groove by the apex of the protruding triangular guide.

[0024] More preferably, the track forming portion further includes an auxiliary guide tongue spaced apart from the locking guide tongue and relatively closer to the through end; the auxiliary guide tongue extends from one side of the groove sidewall to the other side of the groove bottom wall and is inclined toward the closed end, and the interval between the extended end of the auxiliary guide tongue and the other side of the groove sidewall forms part of the insertion direction track segment; and a groove channel serving as a pull-out termination channel is formed on the outer surface of the fixed end region of the auxiliary guide tongue, the pull-out termination channel being non-through in the pull-out direction, thereby forming a pull-out stop transition step at one end near the through end; the groove channel on the locking guide tongue is through in the pull-out direction to form a pull-out guide channel, and both the pull-out guide channel and the pull-out termination channel are arranged in the pull-out direction, thereby both serving as part of the pull-out direction track segment.

[0025] Preferably, the sliding locking member is an elastic locking member, which is installed on the outer surface of the side wall of the mounting chamber.

[0026] Specifically, the elastic locking element is a compression spring, which is mounted on the outer surface of the side wall of the mounting chamber by means of a pressure plate and fasteners.

[0027] Typically, the battery case housing includes a cover and a body connected to each other. The closed end of the cover is formed as the insertion end. The housing snap-fit ​​track groove structure is disposed on the outer surface of the side wall of the cover. The track groove extends from the insertion end through the end face of the insertion end to the open end of the cover, but does not penetrate the end face of the open end of the cover.

[0028] Preferably, the battery box housing of the battery box assembly has one of a foolproof groove and a foolproof protrusion, and the other of the foolproof groove and foolproof protrusion is correspondingly formed on the side wall of the mounting chamber.

[0029] As a particularly preferred arrangement, the mounting base is provided with a hot water connector and a cold water connector, and the mounting chamber is formed on the mounting base with the mounting opening facing downwards, the mounting opening being located on the bottom surface of the shower and away from the hot water connector and the cold water connector.

[0030] Based on the above-mentioned battery box assembly technical solution, the present invention further provides a shower system, including a shower head and a shower unit installed below the shower head, wherein the shower head is connected to the water outlet pipe of the shower unit, and the shower unit is the shower unit described in any of the above technical solutions.

[0031] Through the above-described technical solution of the present invention, the shower of the basic technical solution of the present invention, in order to ensure the personal safety of the user, firstly adopts DC power supply, that is, adopts an encapsulated battery box assembly. Since the internal battery and circuit board are encapsulated inside the battery box assembly, it can ensure the moisture-proof and moisture-proof properties of the battery and circuit board themselves. More uniquely, after the battery box assembly of the present invention is inserted and installed in place, its locking does not require conventional fasteners for installation and disassembly. Specifically, a housing snap-fit ​​track groove structure is uniquely formed on the side wall of the battery box assembly. This housing snap-fit ​​track groove structure includes a track groove and a sliding locking element. Through this unique housing snap-fit ​​track groove structure formed on the side wall of the battery box housing, after installation, it cooperates with the sliding locking element (preferably an elastic locking element) such as an elastic pin at the installation part, so that installation and disassembly can be achieved simply by pressing the pressing end of the battery box housing. It is very convenient and reliable, and facilitates the assembly, charging and maintenance of the battery box assembly. It can be effectively used in environments such as shower rooms that require special moisture protection and have high requirements for the convenience of installation and disassembly.

[0032] In particular, in the preferred embodiment of the present invention, the showerhead is designed for the humid environment of a shower room. Since it is installed below the showerhead and is subject to frequent rinsing from water droplets and even water flow, moisture protection of the showerhead's power supply section is crucial. These specific characteristics make the power supply of the showerhead a challenging technical problem to solve. To address this, the present invention employs a targeted structural design, resulting in a unique and effective overall sealing mechanism. The showerhead of the present invention has the installation opening of the mounting chamber facing downwards, effectively preventing water from splashing into the mounting chamber when the showerhead's water flows downwards. Furthermore, because the installation opening faces downwards, the present invention allows the battery interface of the battery box assembly to be located on its insertion end face. This ensures that the circuit connection portion of the battery box assembly that supplies power to the outside is located at the innermost part of the mounting chamber, effectively reducing the erosion of the circuit connection portion by moisture in the shower room.

[0033] Furthermore, since moisture and humidity prevention of the circuit connection parts for power supply to external devices is a key technical challenge, conventional sealing methods are insufficient to meet the requirements. Conventional sealing methods generally compress the seal by applying tightening force with fasteners, utilizing the elastic deformation of the seal itself for sealing. However, the elasticity of the seal itself is limited, and over time, aging, plasticization, and hardening inevitably occur, resulting in sealing gaps. Moreover, conventional fasteners (such as threaded fasteners) also tend to loosen after a period of tightening, failing to provide a consistently stable tightening force. This leads to defects such as moisture intrusion and incomplete sealing. Therefore, in a preferred embodiment of the present invention, a sealing element is provided in the circuit interface groove. After the battery box assembly is inserted into the mounting cavity and locked in place, the battery connector on the cover is aligned with and electrically connected to the battery interface portion contained in the circuit interface groove. The cover is pressed against the insertion end face of the battery box assembly by the elastic force of the elastic device provided between the bottom wall of the mounting cavity and the cover, thereby pressing the sealing element to form a seal for the electrical connection between the battery connector and the battery interface portion. As can be seen, this invention actually forms a unique sealing form that is dynamically adjustable and continuously effective. After the pressure cap is pressed into place to achieve the insertion of the circuit connector and the circuit interface, the pressure cap simultaneously presses the sealing element to form a seal on the circuit connection part. The pressure of the pressure cap on the sealing element mainly relies on the elastic force of the elastic device. Due to the existence of the elastic device, the pressure of the pressure cap on the sealing element is continuous and can be dynamically adjusted. When the sealing element ages, the elastic device can adaptively adjust the force, so that the pressure cap can always effectively press the sealing element, avoiding the defect of conventional sealing forms that do not seal tightly after a period of time. Thus, it can effectively prevent moisture from the battery box assembly and its connecting circuits, and can be effectively used in environments such as shower rooms that require special moisture prevention and high sealing performance.

[0081] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0082] See Figure 1 to Figure 7 As shown, especially see Figure 3 The exploded view of the shower device of the present invention is shown. The shower device of the basic embodiment of the present invention includes a mounting base 8 with a mounting chamber 8d. A battery box assembly 1 is installed in the mounting chamber 8d. The outer surface of the side wall of the battery box housing of the battery box assembly 1 is provided with a housing snap-fit ​​track groove structure 6. The housing snap-fit ​​track groove structure 6 includes a track groove 6k formed on the side wall of the battery box housing and not penetrating the thickness of the side wall. The track groove 6k is structured to cooperate with the sliding locking member of the housing snap-fit ​​track groove structure 6 so that the battery box assembly 1 can be installed, inserted, removed and locked in place.

[0083] As described above, the shower with a unique structure designed specifically for this invention ensures user safety by first using DC power supply, i.e., using a packaged battery box assembly 1. Since the battery 3 and circuit board (preferably PCB board 4) are both packaged inside the battery box assembly 1, it can ensure that the battery 3 and circuit board themselves are protected from moisture. At the same time, the use of DC power supply from the battery box assembly 1 can also prevent the user from being electrocuted. More specifically, after the battery box assembly 1 of the present invention is inserted and installed in place, its locking does not require conventional fasteners for installation and disassembly. Specifically, a housing snap-fit ​​track groove structure 6 is uniquely formed on the side wall of the battery box assembly 1. The housing snap-fit ​​track groove structure 6 includes a track groove 6k and a sliding locking element. Through this unique housing snap-fit ​​track groove structure 6 formed on the side wall of the battery box housing, after installation, it cooperates with a sliding locking element (preferably an elastic locking element) such as an elastic pin at the installation part, so that installation and disassembly can be achieved simply by pressing the pressing end of the battery box housing. This is very convenient and reliable, and facilitates the assembly, charging and maintenance of the battery box assembly 1. It can be effectively used in environments such as shower rooms that require special moisture protection and have high requirements for the convenience of installation and disassembly.

[0084] Based on the above-described basic technical solution of the present invention, since showers are generally installed below the shower head in a shower room, the present invention provides a preferred arrangement that can be combined with any other specific embodiment of the invention described below. Specifically, the shower mounting base 8 is provided with a hot water connector and a cold water connector. The shower mounting base 8 is provided with a mounting chamber 8d with the mounting opening facing downward. The mounting chamber 8d is provided with a battery box assembly 1, and the mounting opening of the mounting chamber 8d is located on the bottom surface of the shower and away from the hot water connector and the cold water connector.

[0085] Specifically, the showerhead of the present invention has the mounting opening of the mounting chamber 8d on the mounting base 8 facing downwards and located on the bottom surface of the mounting base 8, away from the hot water connector and the cold water connector. The advantage of this arrangement is that, as... Figure 2 As shown, the two horizontal connector pipes at the rear of the shower mounting base 8 are used to connect the cold water pipe and the hot water pipe, respectively, while a vertical connector pipe is used to connect the shower head pipe above. This design ensures that the mounting opening of the mounting chamber is located on the bottom surface of the mounting base 8, as far away as possible from the rear hot and cold water connectors. This effectively prevents leaks or seepage from affecting the battery box assembly 1, even if leaks or seepage occur during use, the relatively distant location of the mounting opening prevents these leaks or seepage from impacting the battery box assembly 1. Furthermore, during use, when the shower head water flows downwards, it effectively prevents water from splashing into the mounting chamber.

[0086] Furthermore, precisely because the installation opening faces downwards, in the preferred embodiment described below, the present invention can provide the battery interface portion of the battery box assembly 1 on the end face of its insertion end 21. For example, a circuit interface groove 23 can be provided on the end face of the insertion end 21, so that the circuit interface portion of the battery box assembly 1 is accommodated in the circuit interface groove 23. This ensures that the circuit connection portion of the battery box assembly 1 that supplies power to the outside is located at the innermost part of the installation chamber, thereby effectively reducing the erosion of the circuit connection portion by water vapor in the shower room.

[0087] Based on the above technical solution, furthermore, within the installation chamber 8d, from its top closed end to its bottom installation opening, an elastic device, a pressure cover 9, and a battery box assembly 1 can be installed sequentially.

[0088] Specifically, the insertion end 21 of the battery box assembly faces the pressure cover 9 (the other end opposite to the insertion end 21 is the pressing end of the battery box assembly 1), and a circuit interface groove 23 is formed on the end face of the insertion end 21. A sealing element (preferably a sealing ring 5 installed along the periphery of the circuit interface groove 23) is provided in the circuit interface groove 23. When the battery box assembly 1 is inserted into place and locked, the battery connector 11 on the pressure cover 9 is electrically connected to the battery interface portion accommodated in the circuit interface groove 23.

[0089] Furthermore, the elastic device presses against the cover 9, and the cover is pressed against the end face of the insertion end 21 of the battery box assembly 1 by the elastic force of the elastic device, thereby pressing the seal to form a seal for the electrical connection between the battery connector 11 and the battery interface.

[0090] Thus, in the preferred embodiment of the present invention, a sealing element is provided in the circuit interface groove 23. After the battery box assembly 1 is inserted into the mounting cavity and locked in place, the battery connector 11 on the cover 9 is aligned with the battery interface portion contained in the circuit interface groove 23 and naturally electrically connected. Furthermore, the cover 9 is pressed against the end face of the insertion end 23 of the battery box assembly 1 by the elastic force of the elastic device provided between the bottom wall of the mounting cavity and the cover 9, thereby pressing the sealing element to form a seal for the electrical connection between the battery connector 11 and the battery interface portion.

[0091] As can be seen, the showerhead of this preferred embodiment of the invention actually forms a unique sealing form with dynamic adjustment and continuous action of the clamping force on the sealing element. After the pressure cap 9 is pressed into place to achieve the insertion of the circuit connector 11 and the circuit interface, the pressure cap 9 simultaneously presses the sealing element to form a seal on the circuit connection part. The pressure cap 9 presses the sealing element mainly by the elastic force of the elastic device. Due to the existence of the elastic device, the pressure cap 9 presses the sealing element continuously and can be dynamically adjusted. When the sealing element ages, the elastic device can adaptively adjust the force, so that the pressure cap 9 can always effectively press the sealing element, without the defect of conventional sealing forms that are not tight after a period of time. Thus, it can effectively prevent moisture from the battery box assembly 1 and its connecting circuit, and can be effectively used in environments such as shower rooms that require special moisture prevention and high sealing performance.

[0092] In the above basic technical solution, preferably, the circuit connector 11 can be formed as an integral part with the cover 9 by injection molding or other means, and the elastic device can be a leaf spring, disc spring, coil spring, etc.

[0093] Regarding battery box assembly 1, see Figure 1a As shown, as a specific structural form, it may include a battery case housing, which encapsulates a battery 3 and a circuit board (e.g., PCB board 4) electrically connected to the battery 3. To stably support the battery 3, referring to Figure 1, a battery support plate 25 may be provided inside the battery case housing. The battery support plate 25 has a semi-circular groove for placing the battery 3. The battery case housing has an opposing insertion end 21 and a pressing end 22. A circuit interface groove 23, as described above, communicating with the interior of the battery case housing is formed on the end face of the insertion end 21. The battery interface portion of the circuit board extends from the interior of the battery case housing and is accommodated within the circuit interface groove 23. A sealing element such as a sealing ring 5 is installed within the circuit interface groove 23, so that when the battery interface portion of the circuit board is connected to a circuit connector 11 or similar device on the cover plate 9, an effective seal can be formed through the sealing element. Figure 1aIn the middle, the individual cells of battery 3 can be connected in series. They can be connected by the negative terminal through the electrical connection piece (not shown in the figure) on the inner wall of the cover 2a, and the positive terminal is connected by two independent electrical contacts on the PCB board 4 to form a series electrical connection.

[0094] The battery box assembly 1 of the present invention is not limited to Figure 1a The box structure shown, for example Figure 1b Another structural form shown is, with Figure 1a Compared to the implementation shown, this Figure 1b The displayed structure features a taller lid 2a and a base-like body 2b. The body 2b also has a battery support plate 25 with a semi-circular groove conforming to the shape of the individual battery cells. In Figure b, the individual battery cells can be connected in parallel. The negative terminals of two individual battery cells are electrically connected via a negative terminal connecting piece 26, and the positive terminals are electrically connected via a positive terminal connecting piece 27. One end of the positive terminal connecting piece is electrically connected to an electrical contact on a circuit board (e.g., PCB board 4), thus forming a parallel electrical connection. Of course, the battery assembly 1 of this invention can adopt various structural forms and is not limited to any particular one. Figure 1a and Figure 1b All forms thereof should fall within the scope of the technical concept of this invention.

[0095] Referring to Figure 1, the circuit board can be a PCB board 4. The battery interface section of the PCB board 4 can include a charging interface 4a and a discharging interface 4b, both of which are housed within the circuit interface slot 23. With the battery box assembly 1 installed and inserted, the circuit connector 11 on the cover plate 9 can be inserted into the discharging interface 4b for external power supply. When the battery 3 needs maintenance charging, the battery box assembly 1 can be removed and charged through the charging interface 4a, which is quite convenient.

[0096] In addition, to ensure that the battery box assembly 1 is not installed backwards or incorrectly during installation, preferably, one of the anti-mistake groove 7 and the anti-mistake protrusion is formed on the battery box housing of the battery box assembly 1, and the other of the matching anti-mistake groove 7 and the anti-mistake protrusion is formed on the side wall of the mounting chamber 8d. This makes it easier for the end user to identify the installation direction of the battery box assembly 1. If the anti-mistake groove 7 is not aligned with the matching protrusion of the mounting part, the battery box assembly 1 will not be able to be installed into the mounting part.

[0097] As a more preferred embodiment, referring to Figure 1, a circuit interface groove 23 is formed on one side of the end face of the insertion end 21 of the battery box housing. A non-penetrating balance sealing groove 20 is formed on the other side of the end face of the insertion end 21, and a sealing element mounting structure is formed within the balance sealing groove 20. This balance sealing groove 20 mainly serves to stabilize the sealing process. In the installed state, the sealing ring in the circuit interface groove 23 is compressed externally. At this time, this balance sealing groove 20 is used on the other side of the insertion end 21, and a sealing ring (i.e., a balance spare sealing element 24) is also installed inside it. Thus, during installation, the component that seals and compresses the end face of the insertion end 21 (hereinafter referred to as the pressure cap 9) can maintain overall balance, preventing incomplete compression and misalignment, ensuring the normal compression and sealing of the sealing ring in the circuit interface groove 23. Furthermore, if the sealing ring in the circuit interface groove 23 is damaged or lost, and a new sealing ring is temporarily unavailable, the sealing ring in the balance sealing groove 20 can be removed as a replacement, prioritizing the sealing of the circuit interface groove 23.

[0098] Based on the above technical solutions, see [link to relevant documentation]. Figure 2 The elastic device can be specifically selected as a pair of springs 10, and the pressure cover 9 can be provided with a corresponding spring seat 14 to ensure stable and reliable installation of the springs 10. Of course, the elastic device can also be in the form of other elastic elements, such as leaf springs or disc springs. In addition, the battery connector 11 on the pressure cover 9 can be connected to the electrical components of the shower, such as the display screen, via a wire 15.

[0099] The battery box assembly 1 of this invention is locked in place using a detachable locking method after insertion. This locking method can be of various types, such as a fixed pin or a rotating stop block. However, since the showerhead of this invention is installed in the shower room and is fixedly installed below the shower head, the unique insertion structure with the installation opening facing downwards is specifically designed due to unique moisture-proof requirements. That is, the battery box assembly 1 needs to be installed and removed from the bottom of the showerhead. The battery box assembly 1 needs to be installed and removed frequently for maintenance, which makes the convenience of installation and removal particularly important. Moreover, this convenience of installation and removal cannot affect the reliability of the aforementioned seal, that is, it needs to provide reliable and effective support for the battery box assembly 1. Although conventional locking methods such as fixed pins and rotating stop blocks can basically achieve the locking function, the convenience and reliability of installation and removal need to be improved. Given the unique installation position of the battery box assembly 1 on the bottom surface of the showerhead of this invention, and the fact that the fixed installation position of the showerhead is generally low, this structural design that allows for easy installation and removal is relatively difficult to achieve.

[0100] As a unique preferred method, see Figures 2 to 9The battery box assembly 1 has a housing snap-fit ​​track groove structure 6 on the outer surface of the side wall of the battery box housing. The housing snap-fit ​​track groove structure 6 includes a track groove 6k formed on the side wall of the battery box housing and not penetrating the thickness of the side wall of the battery box housing. The track groove 6k is shaped to cooperate with the sliding locking member of the housing snap-fit ​​track groove structure 6 so that the battery box assembly 1 can be installed, inserted, removed and locked in place.

[0101] Specifically, the track groove 6k extends from the insertion end 21 through the end face of the insertion end 21 toward the bottom of the battery box housing (i.e., toward the aforementioned pressing end 22). Thus, the track groove 6k may include a through end 6k1 through the end face of the insertion end 21, a closed end 6k2 opposite to the through end 6k1, two side walls of the groove, and a bottom wall of the groove 6k3. At least an insertion track 17, a locking groove 6g, and a pull-out track 18 may be formed in sequence within the track groove 6k. Correspondingly, a locking member insertion groove 8a is provided on the side wall of the mounting chamber of the battery box assembly 1, and the insertion end of the sliding locking member (preferably an elastic locking member installed on the side wall of the mounting chamber 8d) extends into the interior of the mounting chamber through the locking member insertion groove 8a, thereby cooperating with the track groove 6k to allow the battery box assembly 1 to be inserted, removed, and locked in place.

[0102] Specifically, the sliding locking member and the track groove 6k are configured to cooperate as follows: In the insertion operation state, the insertion end 21 of the battery box assembly is inserted into the installation opening of the mounting chamber, and the extension end of the sliding locking member enters the insertion track 17 from the through end 6k1 of the track groove 6k. The bottom of the battery box assembly 1 (e.g., the pressing end 22) can be pushed, causing the battery box assembly 1 to push the pressure cover 9 inward against the elastic force of the elastic device, thereby causing the extension end of the sliding locking member to slide relative to the insertion track 17. Specifically, see Figure 9 As shown, the sliding locking member extends into the mounting chamber via the locking member insertion groove 8a. Although the sliding locking member has a certain degree of elasticity, its initial position 16a within the mounting chamber is essentially fixed after insertion. When the user inserts the battery box assembly 1 through the mounting opening of the mounting chamber, the sliding locking member slides relative to the insertion track 17 via the through end 6k1 of the track groove 6k, thereby allowing the battery box assembly 1 to be inserted and installed. (Continue to see...) Figure 9In the locked state, the battery box assembly 1 moves to the insertion end of the sliding locking member, enters the locking groove 6k, and is locked in place. After insertion and installation, the user can remove the pressing force of the pressing end 22 of the battery box assembly 1. The cover 9, under the elastic force of the elastic device, presses against the end face of the insertion end 21 of the battery box housing, tightening the seal (e.g., sealing ring 5), effectively sealing the periphery of the circuit interface groove 23. Since the insertion and installation are in place, the battery connector 11 on the cover 9 is inserted into the battery interface portion of the circuit board housed in the circuit interface groove 23, thereby forming an electrical connection to external power supply. Furthermore, if the battery 3 is depleted or malfunctions and needs to be disassembled for charging and maintenance, the user can perform a pull-out operation. In the pull-out operation state, the insertion end of the elastic locking member is guided from the locking groove 6g into the pull-out track 18, and the battery box assembly 1 is pulled outwards under the elastic thrust of the elastic device.

[0103] The unique housing snap-on track groove structure formed on the side wall of the battery box housing of this invention, after installation, cooperates with the elastic locking parts such as the elastic snap pins at the installation location. As needed, installation and disassembly can be achieved simply by pressing the pressing end of the battery box housing, which is very convenient and reliable. It facilitates the assembly, charging and maintenance of the battery box assembly 1, and can effectively prevent water and moisture.

[0104] Referring to Figure 1, as a specific structural form, the battery box assembly 1 may include a cover 2a and a body 2b connected to each other. The open ends of the cover 2a and the body 2b are connected to each other, so that the closed end of the cover 2a opposite to its open end forms the insertion end 21 of the battery box body, and the closed end of the body 2b opposite to its open end forms the pressing end 22. The housing snap-fit ​​track groove structure 6 can be provided on the outer surface of the side wall of the cover 2a. The track groove 6k extends from the insertion end 21 through the end face of the insertion end 21 to the open end of the cover 2a, but does not penetrate the end face of the open end of the cover 2a. This separate structure of the cover 2a and the body 2b facilitates the installation of individual batteries 3 into the battery box and allows for convenient maintenance in case of circuit board failure.

[0105] As a key part of the disassembly and assembly structure of this invention, see Figure 1. Figure 8 and Figure 9 More specifically, the housing snap-fit ​​track groove structure 6 may include a track forming part disposed in the track groove 6k, which divides the space in the track groove 6k into sequentially connected insertion track 17, locking groove 6g and pull-out track 18, wherein the insertion track 17 sequentially includes an insertion direction track segment 17a and an insertion turning track segment 17b, and the pull-out track 18 sequentially includes a pull-out turning track segment 18b and a pull-out direction track segment 18a, and the locking groove 6g is located between the insertion turning track segment 17b and the pull-out turning track segment 18b.

[0106] Furthermore, the track forming part may include a locking guide tongue 6b and a protruding triangular guide portion 6c. The locking guide tongue 6b extends from one side wall 6k4 to the other side wall 6k5 on the bottom wall 6k3 of the groove and is inclined toward the closed end 6k1. The gap between the extended end of the locking guide tongue 6b and the other side wall 6k5 forms a component of the insertion direction track segment 17a. A groove channel is provided on the outer surface of the fixed end of the locking guide tongue 6b, which forms a component of the extraction direction track segment 18a. The protruding triangular guide portion 6c is located at the closed end 6k3 of the track groove 6k. The end wall of the locking guide tongue 6b protrudes and is spaced apart from each other, thus forming an insertion corner 6d and an extraction corner 6e on both sides of the end wall of the closed end 6k3. The gap between one side of the protruding triangular guide 6c and the locking guide tongue 6b forms an insertion curved track segment 17b, and the gap between the other side of the protruding triangular guide 6c and the locking guide tongue 6b forms an extraction curved track segment 18b. Thus, the insertion track segment 17a can naturally connect with the insertion curved track segment 17b through the insertion corner 6d, and the extraction curved track segment 18b connects with the extraction track segment 18a through the extraction corner 6e. Furthermore, a locking groove 6g is formed on the side of the locking guide tongue 6b facing the apex of the protruding triangular guide 6c, so that the locking groove 6g is located between the insertion curved track segment 17b and the extraction curved track segment 18b.

[0107] Particularly preferably, the locking groove 6g is partially offset from the apex 6f of the protruding triangular guide 6c, which is further offset towards one side of the groove sidewall 6k4, thus forming a misaligned pull-out guide structure at the locking groove 6g. In the pulled-out state, the battery box assembly 1 is pushed inward, and the extended end of the sliding locking member is pushed into the pull-out track at the locking groove by the apex 6f of the protruding triangular guide 6c. After the pushing force is released, the battery box assembly can be pulled outward under the elastic thrust of the elastic device. (For the operation process of this misaligned pull-out guide structure, please refer to the unlocking operation process of the battery box assembly mounting structure below.)

[0108] Although simply providing the locking guide tongue 6b is sufficient to essentially form the insertion direction track segment 17a and the withdrawal direction track segment 18a of the present invention, for a more effective guiding effect, preferably, see Figure 1, Figure 8 and Figure 9The track forming section may further include an auxiliary guide tongue 6a spaced apart from the locking guide tongue 6b and relatively closer to the through end 6k1 of the track groove 6k. This auxiliary guide tongue 6a extends from one side wall 6k4 to the other side wall 6k5 on the bottom wall 6k3 of the groove and is inclined towards the closed end 6k2. The gap between the extended end of the auxiliary guide tongue 6a and the other side wall 6k5 also forms part of the insertion direction track segment 17a. Furthermore, correspondingly, a groove channel serving as a pull-out termination channel 6i may be formed on the outer surface of the fixed end region of the auxiliary guide tongue 6a. This pull-out termination channel 6i is not through in the pull-out direction B, thereby forming a pull-out stop transition step 6j at one end near the through end 6k1 of the track groove 6k. In this way, the groove channel on the locking guide tongue 6b can be connected along the pull-out direction B to form a pull-out guide channel 6h. The pull-out guide channel 6h and the pull-out termination channel 6i on the auxiliary locking tongue 6a are both arranged along the pull-out direction B, thus both serving as components of the pull-out direction track segment 18a.

[0109] See Figure 2 The elastic locking element is preferably a compression spring 12, which can be mounted on the outer surface of the side wall of the mounting chamber via a pressure plate 13 and fasteners. Specifically, for example, the compression spring 12 can be formed in a [shape], with its fixed end inserted into the outer surface of the side wall of the mounting chamber via a compression spring mounting hole 8b, and its extended end extending into the interior of the mounting chamber via a locking element extension groove 8a on the side wall of the mounting chamber. The outside of the fixed end of the compression spring 12 can be covered and fixed by the pressure plate 13, which is fastened by fasteners and pressure plate fastening holes 8c.

[0110] In addition, the present invention also provides a shower system, including a shower head and a shower unit installed below the shower head, wherein the shower head is connected to the water outlet pipe of the shower unit, and the shower unit is the shower unit described in any of the above embodiments.

[0111] The above is combined with Figure 1. Figure 8 and Figure 9 A preferred structure of the housing snap-fit ​​track groove structure 6 of the present invention has been described. However, it should be noted that the housing snap-fit ​​track groove structure 6 of the present invention can have various variations. For example, the above-described structure may only have a larger locking guide tongue 6b, and the protruding triangular guide portion 6c is not limited to the form shown in the figure. Furthermore, although the preferred structure of the housing snap-fit ​​track groove structure 6 shown in the figure has its own unique advantage of convenient installation and disassembly, it is not limited to the preferred structure. The following description of the shower and its dynamic operation process according to the preferred embodiment of the present invention will further illustrate some simple variations based on a clear understanding of the function and dynamic operation of the housing snap-fit ​​track groove structure 6.

[0112] See Figure 1a, Figure 1b , Figure 8 and Figure 9 The battery box assembly 1 includes a cover 2a and a body 2b. The body 2b houses two batteries 3, which are connected to a PCB board 4 after the electrodes are connected. The PCB board 4 has a charging interface 4a and a discharging interface 4b, and contains charging / discharging circuitry and indicator lights. After the cover 2a and body 2b are closed, they can be ultrasonically welded together to form a seal, or a detachable sealed connection can be formed using fasteners and seals. Specifically, a sealing groove can be formed on the open end of the body 2b, which can accommodate two sealing gaskets. After the cover 2a and body 2b are connected, they form a... Figure 8 The battery box assembly 1 is shown. According to... Figure 8 As shown, the upper end of the cover 2a forms an insertion end 21. A circuit interface groove 23 is formed on one side of the end face of the insertion end 21. The charging interface 4a and discharging interface 4b of the PCB board are accommodated within the circuit interface groove 23. A sealing element mounting structure (generally a sealing ring mounting groove) is formed around the periphery of the circuit interface groove 23 to accommodate the sealing ring 5 during subsequent installation. A balancing sealing groove 20 is formed on the other side of the end face of the insertion end 21. A sealing element mounting structure is also formed around the periphery of this balancing sealing groove, which can also accommodate the sealing ring 5 during installation. This ensures that when the cover 9 is pressed against the end face of the insertion end 21, the left and right sides of the insertion end 21 are balanced, preventing the sealing ring 5 from being improperly pressed in. Furthermore, a foolproof groove 7 is formed on the outer surface of the side wall of the cover 2a. This foolproof groove 7 is mainly used to prevent the battery box assembly 1 from being installed in the wrong direction during installation. Only when the installation direction is correct can it be pressed and assembled; otherwise, it will press against the structure on the mounting base 8 and cannot be assembled, thus preventing misassembly.

[0113] Uniquely, see Figure 8 and Figure 9The outer surface of the cover 2a is formed with a shell snap track groove structure 6, which includes a track groove 6k and a track forming part disposed in the track groove 6k. The track groove 6k includes a through end 6k1 that passes through the end face of the insertion end 21, a closed end 6k2 opposite to the through end, two side walls of the groove and a bottom wall of the groove 6k3. The track forming part divides the internal space of the track groove 6k into an insertion track 17, a locking groove 6g and an extraction track 18 connected in sequence. The track forming section includes an auxiliary guide tongue 6a, a locking guide tongue 6b with a locking groove 6g, and a protruding triangular guide portion 6c protruding from the end wall of the closed end 6k2 toward the locking guide tongue 6b. The auxiliary guide tongue 6a and the locking guide tongue 6b are spaced apart from each other, and the locking guide tongue 6b is located between the auxiliary guide tongue 6a and the protruding triangular guide portion 6c. The auxiliary guide tongue 6a is closer to the through end 6k1 of the track groove 6. Both the auxiliary guide tongue 6a and the locking guide tongue 6b extend from one side wall 6k4 to the other side wall 6k5 on the bottom wall 6k3 of the groove and are inclined toward the closed end 6k2. The extended ends of the auxiliary guide tongue 6a and the locking guide tongue 6b are spaced apart from the other side wall 6k5. These intervals form part of the insertion direction track segment 17a. Furthermore, the outer surface of the fixed end of the locking guide tongue 6b is provided with a groove channel for forming a component of the pull-out direction track segment 18a. The outer surface of the fixed end region of the auxiliary guide tongue 6a is formed with a groove channel serving as a pull-out termination channel 6i. This pull-out termination channel 6i is not continuous along the pull-out direction B, thus forming a pull-out stop transition step 6j at one end near the continuous end 6k1. The groove channel on the locking guide tongue 6b is continuous along the pull-out direction B to form a pull-out guide channel 6h. Both the pull-out guide channel 6h and the pull-out termination channel 6i are arranged along the pull-out direction B, thus both serving as components of the pull-out direction track segment 18a. Furthermore, the locking guide tongue 6b and the protruding triangular guide portion 6c are spaced apart from each other, and a locking groove 6g is formed on the side of the locking guide tongue 6b facing the apex 6f of the protruding triangular guide portion 6c. The protruding triangular guide portion 6c protrudes from the end wall of the closed end 6k2, thereby forming an insertion corner portion 6d and an extraction corner portion 6e on both sides of the closed end 6k2. The intervals between the two sides of the protruding triangular guide portion 6c and the locking guide tongue 6b respectively form an insertion turning track section 17b and an extraction turning track section 18b. Thus, the insertion direction track section 17a is connected to the insertion turning track section 17b through the insertion corner portion 6d, thereby forming an insertion track 17; the extraction turning track section 18b is connected to the extraction direction track section 18a through the extraction corner portion 6e, thereby forming an extraction track 18.In this preferred structure, more uniquely, the locking groove g is partially offset from the apex 6f of the protruding triangular guide 6c by being biased toward one side of the groove sidewall 6k4. This forms a pull-out guide structure for driving the locking member in the locking groove 6h to slide toward the pull-out turning track section 18b via the apex 6f of the protruding triangular guide 6c in the pull-out operation state.

[0114] When the battery box assembly 1 is installed onto a mounting base 8, such as that of a shower, the mounting base 8 has a mounting chamber. One end of the mounting chamber is a mounting opening, and the other end is a mounting closed end. A pair of springs 10 (acting as elastic devices), a pressure cap 9, and the battery box assembly 1 can be sequentially installed within the mounting chamber from the mounting closed end (i.e., from the inside to the outside). A sealing ring 5 is installed in both the circuit interface groove 23 and the balance sealing groove 20 of the battery box assembly 1. A locking member insertion groove 8a is provided on the side wall of the mounting chamber, and a compression spring 12, acting as an elastic locking member, is installed on the side wall of the mounting chamber. The insertion end of the compression spring 12 extends into the interior of the mounting chamber via the locking member insertion groove 8a. The compression spring 12 is mounted on the outer surface of the side wall of the mounting chamber via a pressure plate 13 and fasteners. Specifically… The compression spring 12 is shaped like a [ ], with its fixed end inserted into the outer surface of the side wall of the mounting chamber through the compression spring mounting hole 8b, and its extended end extending into the interior of the mounting chamber through the locking member on the side wall of the mounting chamber through the extension groove 8a. The fixed end of the compression spring 12 is covered and fixed by a pressure plate 13, which is fastened by fasteners and pressure plate fastening holes 8c.

[0115] See Figure 9 As shown, in the insertion operation state, the insertion end 21 of the battery box assembly 1 is inserted into the installation opening of the installation chamber. The extension end of the compression spring 12, starting from the initial position 16a, is pushed by the pressing end 22 of the battery box assembly 1, causing the battery box assembly 1 to be inserted. The extension end of the compression spring 12 enters the insertion direction track 17a (i.e., the first part of the insertion track 17) from the through end 6k1 of the track groove 6k, and passes through the interval between the auxiliary guide tongue 6a and the side wall 6k5 of the other side groove (i.e., the insertion middle position 16b), and the interval between the locking guide tongue 6b and the side wall 6k5 of the other side groove, reaching the insertion inflection point position 16c (i.e., the insertion corner part 6d mentioned above). Due to the elasticity of the compression spring 12 itself and the pressing end 22, the extension end of the compression spring 12 then moves along the insertion bend track 17b to the insertion locking position 16d. At this time, the extension end of the compression spring 12 is engaged in the locking groove 6g, thus inserting and installing in place.

[0116] With the battery inserted and installed in the correct position, the user releases the pressure of the pressing end 22. The extended end of the compression spring 12 remains locked. In the locked state, the pressure cover 9, under the elastic force of the elastic device, presses against the end face of the insertion end 21 of the battery box housing, thus tightening the sealing ring 5 and forming an effective seal around the circuit interface groove 23. At this time, since the battery is inserted and installed in the correct position, see [link to relevant documentation]. Figure 5 The battery connector 11 (which can generally be injection molded as a whole) provided on the cover 9 is inserted into the discharge interface 4b of the PCB board 4 housed in the circuit interface slot 23, and connected to the electrical components of the shower (such as the display screen) via the wire 15, thereby forming an electrical connection to external power supply.

[0117] See also Figure 9 Furthermore, if the battery 3 is depleted or malfunctions and needs to be disassembled for charging, maintenance, or repair, the user can perform a pull-out operation. In the pull-out operation state, the user first lightly presses the pressing end 22 of the battery box assembly 1, causing the battery box assembly 1 to be pushed against the elastic force of the spring 10 and move inward a short distance. At this time, the extension end of the compression spring 12 disengages from the locking groove 6g. Because the battery box assembly 1 is pushed inward and moves a short distance, the apex 6f of the protruding triangular guide portion 6c is partially offset from the side wall 6k4 relative to the locking groove 6g. Therefore, this apex 6f will touch the extension end of the compression spring 12, driving it to deform and enter the pull-out turning track 18b, thereby reaching the pull-out turning point position 16e (i.e., corresponding to the pull-out turning part 6e). When the pressing force of the pressing end 22 is removed, the battery box assembly 1 pops out under the elastic force of the spring 12. It first enters the pull-out direction track section 18a, and then passes through the pull-out guide channel 6h (corresponding to the middle pull-out position 16f) in the fixed end area of ​​the locking guide tongue 6b, and reaches the pull-out termination channel 6i (corresponding to the pull-out end stop position 16e) in the fixed end area of ​​the auxiliary guide tongue 6a. Since the pull-out termination channel 6i is not through, a pull-out stop transition step 6j is formed at one end of the through end 6k1 near the track groove 6k. In this way, the battery box assembly 1 will be hooked and will not pop out directly and fall to the ground. At this time, the user can pull up the extension end of the compression spring 12 from the outside, so that the battery box assembly 1 can be popped out without obstruction. Additionally, it should be noted that although the pull-out guide structure of the present invention is achieved in this preferred structure by the ingenious form of partially offsetting the apex 6f of the locking groove 6g and the protruding triangular guide portion 6c, the pull-out guide structure is not limited to this. For example, it can also be achieved by forming a stop step for the stop spring 12 to recover its deformation at the position corresponding to the locking groove 6g. These are all within the protection scope of the present invention.

[0118] As described above in the specific embodiments of the present invention, the shower of the present invention uses DC power supply. The battery 3 and circuit board in the battery box assembly 1 are encapsulated by the battery box body. The shower of the present invention has the mounting opening of the mounting chamber 8d on the mounting base 8 facing downwards and located on the outer side of the bottom surface of the mounting base 8, away from the hot water connector and cold water connector. In this way, even if the hot water connector or cold water connector leaks or seeps during use, the relatively distant position of the mounting opening can effectively prevent these leaks or seeps from affecting the battery box assembly 1. Moreover, during use, when the water flow from the shower head is directed downwards, water splashing into the mounting chamber can be effectively prevented. Furthermore, precisely because the mounting opening faces downwards, the present invention can place the battery interface part of the battery box assembly 1 on the end face of its insertion end 21. For example, a circuit interface groove 23 can be provided on the end face of the insertion end 21, so that the circuit interface part of the battery box assembly 1 is accommodated in the circuit interface groove 23. This ensures that the circuit connection part for external power supply of the battery box assembly 1 is located at the innermost part of the mounting chamber, thereby effectively reducing the corrosion of the circuit connection part by water vapor in the shower room.

[0119] In particular, the preferred embodiment of the present invention achieves electrical connection between the battery interface of the circuit board and the outside through the circuit interface groove 23, and a sealing element mounting structure is formed within the circuit interface groove 23. After installation, the circuit interface groove 23 can effectively seal the circuit interface groove 23. Unlike conventional sealing methods, the shower of the present invention actually forms a unique sealing method with dynamic adjustment and continuous action of the sealing force. After the pressure cover 9 is pressed into place to achieve the insertion of the circuit connector 11 and the circuit interface, the pressure cover 9 simultaneously presses the sealing element to form a seal on the circuit connection part. The pressure cover 9 presses the sealing element mainly by means of... The elastic force of the elastic device ensures that the pressure of the cover 9 on the seal is continuous and dynamically adjustable. When the seal ages, the elastic device can adaptively adjust the force, so that the cover 9 can always effectively press the seal, avoiding the defect of conventional sealing methods that become loose after a period of time. This effectively protects the battery box assembly 1 and its connecting circuits from moisture, making it suitable for use in environments requiring special moisture protection and high sealing performance, such as shower rooms. It can continuously and effectively protect the battery box assembly 1, its connecting circuits, and electrodes from moisture.

[0120] Meanwhile, to accommodate the installation orientation of the shower and facilitate installation and disassembly, the battery box housing of this invention features a unique housing snap-fit ​​track groove structure 6 on its side wall. This greatly facilitates installation and disassembly; installation and disassembly can be achieved simply by pressing the pressing end of the battery box housing, making it extremely convenient and reliable. This facilitates the assembly, charging, and maintenance of the battery box assembly 1 and effectively prevents water and moisture damage. This invention can be widely used in various products with replaceable batteries and high sealing requirements.

[0121] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0122] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0123] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
