Description

Technical Field

[0001] This utility model belongs to the field of shower head technology and relates to an electric shower head. Background Technology

[0002] With the increasing popularity of outdoor sports, electric showerheads, as an important device to meet people's cleaning needs in outdoor settings, are seeing their usage frequency and application range continuously expand. After activities such as camping, fishing, and wilderness exploration, people often need to use electric showerheads for personal hygiene. Electric showerheads differ from ordinary household showerheads. Because they contain electronic components such as water pumps, batteries, and control panels, electric showerheads typically require a waterproof design and have higher waterproof performance requirements to prevent external water from entering the showerhead body and damaging the electronic components.

[0003] For example, an electric shower head disclosed in patent literature (application number: 202323034092.9) includes a shower head housing, a power storage component, a pump body, and a mounting shell. The shower head housing has a head and a handle. The mounting shell is fixed in the first cavity of the handle. The power storage component is disposed on the mounting shell, and the mounting shell is fixedly connected to the inner wall of the handle by screws. In use, pressing the switch button activates the pump body, and water is guided to the pump body through an external hose and a first connecting pipe, and then sprayed out through a second connecting pipe to the head assembly. This electric shower head has the following shortcomings in actual use: the side of the handle is open and detachably connected to a cover. While this design facilitates the disassembly and maintenance of the power storage component and the pump body, the outer wall of the handle gets wet during use, and it is difficult to achieve an absolute seal between the cover and the handle. Therefore, after frequent use, external water can easily seep into the handle through the gap between the cover and the handle. Once water enters the handle, it can cause short circuits or damage to electronic components, affecting the use of the shower head and reducing its lifespan. Therefore, this electric shower head has insufficient waterproof performance. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an electric shower head that solves the problem of insufficient waterproofing performance of existing electric shower heads.

[0005] The objective of this utility model can be achieved through the following technical solution: an electric shower head, comprising a shower head body and a strip-shaped mounting bracket for installing a battery, characterized in that the shower head body comprises a tubular handle and a cylindrical head located at one end of the handle and integrally formed with the handle, the mounting bracket being inserted into the handle from the other end of the handle and fixed inside the handle, the mounting bracket having an outer end wall that matches the shape of the port at the other end of the handle, the outer end wall of the mounting bracket being embedded in the port at the other end of the handle, and a sealing ring being provided between the outer end wall and the inner circumferential surface of the handle.

[0006] In this electric showerhead, the handle is tubular and integrally formed with the head, eliminating the need for a battery cover. This avoids the risk of water leakage caused by seams in traditional split-type handles, thus enhancing the showerhead's waterproof performance from the outset. Furthermore, the battery mounting bracket features a strip design, inserted into the handle from one end. The outer wall of the bracket is embedded in the port at the other end of the handle, and a sealing ring provides a tight seal with the inner circumference of the handle. This secures the mounting bracket within the handle and prevents water from seeping in. Moreover, the sealing ring, in addition to its sealing function, also provides positioning for the outer end of the mounting bracket due to its elasticity. Therefore, the sealing ring serves a dual purpose: sealing and assisting in securing the mounting bracket. This ensures good installation stability and waterproof performance when the mounting bracket is inserted into the handle.

[0007] In the aforementioned electric showerhead, the electric showerhead also includes a water pump disposed within the showerhead body. The inner end of the mounting bracket is U-shaped with its opening facing the head. One end of the water pump is inserted between the two sides of the inner end of the mounting bracket and abuts against these two sides, keeping them in an expanded state and thus engaging with the showerhead body. The outer end wall of the mounting bracket abuts against the handle axially. After the mounting bracket is inserted into the handle, the outer end of the mounting bracket abuts against the handle axially via its outer end wall, and the inner end engages with the handle via its two sides, thus fixing the mounting bracket within the handle. At this point, because the inner end of the mounting bracket has a U-shaped structure with an opening facing the head, and one end of the water pump is inserted between the two sides of the inner end of the U-shape of the mounting bracket and can abut against these two sides, the water pump not only provides water flow power, but also restricts the two sides of the inner end of the mounting bracket from deforming and approaching each other, ensuring that these two sides always remain in an expanded state and can be tightly and reliably engaged with the shower head body. This prevents the mounting bracket from moving outward and ensures that the outer end of the mounting bracket can always seal the port of the handle well, further ensuring that the electric shower head has good waterproof performance.

[0008] In the aforementioned electric shower head, the inner end of the mounting bracket is glued to the inner wall of the shower head body or connected by bolts. Glue bonding offers advantages such as ease of manufacture and low manufacturing cost. Bolted connections provide good stability and effectively prevent axial movement of the mounting bracket, thereby ensuring that the outer end of the mounting bracket always effectively seals the handle port, resulting in better waterproof performance of the electric shower head.

[0009] In the aforementioned electric showerhead, both outer sides of the inner end of the mounting bracket have protruding locking tabs. These tabs abut against the showerhead body, forming a locking connection. When the mounting bracket is inserted into the handle, the tabs abut against the showerhead body to position the bracket, preventing it from moving outwards and ensuring that the outer end of the mounting bracket always effectively seals the handle's port, further guaranteeing the electric showerhead's excellent waterproof performance.

[0010] In the aforementioned electric shower head, the shower head body also includes an inner housing fixedly installed inside the head. The inner housing is cylindrical and open at the top. The side of the inner housing facing the handle has a clearance port through which the water pump passes. The inner end of the mounting bracket extends into the clearance port. The edge of the clearance port is integrally formed with two strip-shaped positioning ribs. The two positioning ribs are respectively located on both sides of the clearance port and are correspondingly set with the locking protrusions on both sides of the inner end of the mounting bracket. The side of the locking protrusion facing the outer end of the mounting bracket abuts against the corresponding positioning rib.

[0011] The upper end of the inner housing is open, facilitating the installation of the water pump inside the shower head body. The additional inner housing within the head, as an independent component, allows for high-precision molding of the positioning ribs. This enables a more stable snap-fit ​​connection through the engagement of the positioning ribs and locking protrusions, effectively preventing the mounting bracket from shifting outwards and ensuring that the outer end of the mounting bracket always effectively seals the handle port, further guaranteeing the electric shower head's excellent waterproof performance. Furthermore, if the positioning ribs fail to secure the connection, only the inner housing needs to be replaced, rather than the entire shower head body, thus reducing maintenance costs and resource waste.

[0012] In the aforementioned electric shower head, two strip-shaped protrusions are integrally formed on the inner circumferential surface of the head. The inner end of the mounting bracket extends between the two protrusions. The two protrusions are correspondingly set with the locking protrusions on both sides of the inner end of the mounting bracket. The side of the locking protrusion facing the outer end of the mounting bracket abuts against the corresponding protrusion.

[0013] By integrally molding a protrusion on the inner wall of the head, the inner shell structure can be eliminated, thus saving materials. At the same time, the protrusion and the snap-fit ​​can cooperate to achieve a stable snap-fit ​​connection, thereby more effectively preventing the mounting bracket from moving outward and ensuring that the outer end of the mounting bracket can always properly seal the port of the handle, further ensuring that the electric shower head has good waterproof performance.

[0014] In the aforementioned electric shower head, the handle is in the shape of a round tube, the outer end wall of the mounting bracket is in the shape of a round plate, and the portion between the U-shaped inner end and the outer end wall of the mounting bracket is in the shape of a rectangular frame with a battery mounting groove formed thereon.

[0015] The outer end wall is integrally molded onto the mounting bracket, which not only reduces the number of parts and makes assembly easier, but also ensures a stable fit between the outer end wall and the handle port after the mounting bracket is securely fixed in position, thereby guaranteeing a sealing effect and improving the waterproof performance of the electric shower head. In actual manufacturing, a sealing ring is fitted onto the outer circumference of the outer end wall of the mounting bracket, abutting against the inner wall of the handle, thus improving sealing. The portion between the U-shaped inner end and the outer end wall of the mounting bracket is rectangular, which not only ensures good structural strength and prevents deformation of the mounting bracket, avoiding problems caused by deformation affecting the sealing effect, but also facilitates the molding of the battery mounting slot, making manufacturing relatively convenient.

[0016] In the aforementioned electric shower head, the inner housing is made of plastic material, the outer circumferential surface of the inner housing abuts against the inner circumferential surface of the head, and the inner housing also has a number of circumferentially arranged strip holes, the length direction of which is arranged along the axial direction of the inner housing.

[0017] By forming several circumferentially arranged strip holes on the inner shell, the inner shell can deform to a certain extent during the process of inserting the inner shell into the head, thereby facilitating the installation of the inner shell. Ultimately, the outer circumferential surface of the inner shell abuts against the inner circumferential surface of the head. This not only improves the installation and fixation effect of the inner shell and ensures a stable engagement between the positioning ribs on the inner shell and the locking protrusions on the mounting bracket, but also makes the inner shell provide internal support for the head, further increasing the structural rigidity of the shower head body and extending the product's service life.

[0018] In the aforementioned electric shower head, the bottom of the inner housing is provided with a positioning notch and an upwardly protruding positioning post is integrally formed. The bottom of the other end of the water pump is embedded in the positioning notch, and the end face of that end can abut against the positioning post.

[0019] This design positions the water pump, improving its installation stability and ensuring that one end of the pump is always positioned between the two sides of the inner end of the mounting bracket. It also restricts the two sides from deforming and moving closer together, thus ensuring that the locking protrusion can always stably abut against the shower head body, forming a tight and reliable locking fit. This prevents water leakage from the handle port due to the mounting bracket moving outward.

[0020] In the aforementioned electric shower head, the middle and upper cross-sections of the head are racetrack-shaped with the long side parallel to the axial direction of the handle, while the lower cross-section is circular. The racetrack-shaped cross-section has a large opening width along its long side, reducing the difficulty and time required for water pump installation and improving production and assembly efficiency. Furthermore, the circular cross-section at the lower end of the head allows for compatibility with standard circular water outlet panels, eliminating the need for custom-made water outlet panel assemblies and reducing manufacturing complexity and cost.

[0021] In the aforementioned electric shower head, the inner housing is bolted to the bottom wall of the head, or the inner housing is glued to the head. The electric shower head also includes a top cover with a sealing cap located at the top of the head. Bolting the inner housing to the bottom wall of the head not only ensures stable installation but also facilitates disassembly and maintenance. Glue bonding, on the other hand, eliminates the need for additional connectors, resulting in a simpler and more compact internal structure and reduced manufacturing costs.

[0022] In the aforementioned electric shower head, two pairs of strip-shaped guide protrusions are integrally formed on the inner wall of the handle near the head end. The length direction of each guide protrusion is arranged along the axial direction of the handle. One side of the inner end of the mounting bracket is slidably engaged between one pair of guide protrusions, and the other side is slidably engaged between the other pair of guide protrusions.

[0023] This design allows the inner end of the mounting bracket to be guided during the insertion of the mounting bracket into the handle, enabling the mounting bracket to be inserted into the handle at a preset angle and trajectory. This ensures that the locking protrusion can move smoothly to the locking position and achieve precise locking, thereby improving the ease of installation of the mounting bracket.

[0024] In the aforementioned electric shower head, the bottom wall of the head has a water outlet hole, the outer end wall of the mounting bracket has a water inlet hole, the water outlet of the water pump is adjacent to the water outlet hole and connected to it through a water outlet pipe, and the water inlet of the water pump is connected to the water inlet hole through a water inlet pipe passing through the handle.

[0025] When using an electric shower head, first connect the external water pipe to the inlet hole, turn on the shower head switch, and the water pump will start running. The water in the water pipe will pass through the inlet hole, inlet pipe, water pump, outlet pipe and outlet hole in sequence, and finally spray out from the shower head's water outlet panel to achieve the spraying function.

[0026] In the aforementioned electric shower head, the inner circumferential surface of the other end of the handle has an annular stepped surface arranged circumferentially. The edge of the outer end wall of the mounting bracket has an annular flange with an annular groove on its outer circumferential surface. The annular flange abuts against the annular stepped surface, and the sealing ring is embedded in the annular groove and located inside the annular stepped surface. The annular groove improves the installation stability of the sealing ring, thereby further improving the sealing reliability and preventing water from seeping into the handle. The inner end of the mounting bracket abuts against the positioning rib through a locking protrusion, limiting the outward displacement and rotation of the mounting bracket, while the outer end of the mounting bracket abuts against the annular stepped surface through the annular flange, limiting the inward displacement of the mounting bracket. This ensures that the mounting bracket is stably fixed inside the handle, guaranteeing that the outer end wall of the mounting bracket can stably seal the port at the other end of the handle, giving the electric shower head good waterproof performance.

[0027] Compared with existing technologies, this electric shower head has the following advantages:

[0028] 1. In this electric shower head, the handle of the shower head body is tubular and integrally formed with the head. The battery cover structure of the handle is eliminated, thus avoiding the risk of water leakage caused by the splicing gaps of the traditional split handle, and enhancing the waterproof performance of the shower head body from the source.

[0029] 2. This electric shower head has good waterproof performance, which can effectively resist the impact of water flow and the influence of humid environment during use, greatly reducing the probability of problems such as short circuits, rust and corrosion of internal components caused by water seepage, and extending the service life of the electric shower head.

[0030] 3. This electric shower head also has the advantages of easy assembly and stable structure. Attached Figure Description

Detailed Implementation

[0041] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0042] Example 1

[0043] like Figures 1 to 3 As shown, this electric shower head includes a shower body 1 made of plastic material, a water pump 2, a top cover 5, and a strip-shaped mounting bracket 4 for mounting a battery 3. The head 1a of the shower body 1 is cylindrical with an open top. The top cover 5 is sealed at the top of the head 1a and blocks the open top. The cross-section of the middle and upper parts of the head 1a is racetrack-shaped, with the long side parallel to the axial direction of the handle 1b. The cross-section of the lower part of the head 1a is circular. The handle 1b of the shower body 1 is cylindrical. The head 1a of the shower body 1 is located at one end of the handle 1b and is integrally formed with the handle 1b. The inner end of the mounting bracket 4 is U-shaped with an opening facing the head 1a, and both outer surfaces of the two sides of this end have protruding locking protrusions 41. After the mounting bracket 4 is inserted into the handle 1b from the other end, the outer end wall 44 of the mounting bracket 4 is embedded in the port of the other end of the handle 1b and abuts against the handle 1b along the axial direction, blocking the port. At the same time, combined with Figure 4 As shown, the side of the protrusion 41 facing the outer end of the mounting bracket 4 abuts against the shower head body 1, thereby fixing the mounting bracket 4 within the handle 1b.

[0044] like Figure 2 As shown, the bottom wall of the head 1a has a water outlet 1a2, which is connected to the water outlet chamber 8 of the electric shower head. The outer end of the mounting bracket 4 has a water inlet 43. The water outlet of the water pump 2 is adjacent to the water outlet 1a2 and connected to it through the water outlet pipe 6. The water inlet of the water pump 2 is connected to the water inlet 43 through the water inlet pipe 7 passing through the handle 1b. Furthermore, the inner circumferential surface of the other end of the handle 1b has an annular stepped surface 1b2 arranged circumferentially. The edge of the outer end wall 44 of the mounting bracket 4 has an annular flange 442 with an annular groove 441 on the outer circumferential surface. The annular flange 442 abuts against the annular stepped surface 1b2. A sealing ring 10 is embedded in the annular groove 441, located inside the annular stepped surface 1b2 and abutting against the inner circumferential surface of the handle 1b.

[0045] The showerhead body 1 contains a circuit board. The battery 3 and the water pump 2 are both electrically connected to the circuit board via wires, enabling the battery 3 to power the water pump 2. The circuit board is existing technology and is not shown in the figure. When using the electric showerhead, first connect the external water pipe to the water inlet hole 43, turn on the power switch, and the water pump 2 starts to run. The water in the water pipe passes through the water inlet hole 43, the water inlet pipe 7, the water pump 2, the water outlet pipe 6, and the water outlet hole 1a2 in sequence, enters the water outlet chamber 8, and finally sprays out from the showerhead's water outlet panel 9 to achieve the spraying function.

[0046] like Figure 5 and Figure 6 As shown, the water pump 2 is installed inside the shower body 1. One end of the water pump 2 is inserted between the two sides of the inner end of the mounting bracket 4, with a slight gap between it and the two sides. Of course, direct contact is also feasible. In this way, when the two sides tend to deform and move closer together, the water pump 2 can contact the two sides, thereby limiting the deformation and movement of the two sides. This keeps the two sides in an expanded state, ensuring that the locking protrusion 41 can always be stably contacted against the shower body 1, forming a tight and reliable locking fit. This prevents the mounting bracket 4 from moving outward and ensures that the outer end of the mounting bracket 4 can always effectively seal the port of the handle 1b, ensuring that the electric shower has good waterproof performance.

[0047] like Figure 3 As shown, the outer end wall 44 of the mounting bracket 4 is in the shape of a circular plate and is perpendicular to the axis of the handle 1b. The outer end wall 44 matches the port shape of the other end of the handle 1b. Thus, the outer end wall 44 of the mounting bracket 4 is used to block the port of the other end of the handle 1b. The part between the U-shaped inner end and the outer end wall 44 of the mounting bracket 4 is in the shape of a rectangular frame and a battery mounting groove 42 is formed on this part.

[0048] like Figure 4 and Figure 6 As shown, the bottom of the inner housing 1c has a positioning notch 1c5 and an integrally formed upward-protruding positioning post 1c4. The bottom of the other end of the water pump 2 is embedded in the positioning notch 1c5, and the end face of this end can abut against the positioning post 1c4. This design can position the water pump 2, improve the installation stability of the water pump 2, ensure that one end of the water pump 2 can always be located between the two sides of the inner end of the mounting bracket 4, and limit the two sides from deforming and approaching each other.

[0049] like Figure 4 and Figure 7As shown, the shower head body 1 also includes an inner housing 1c fixedly disposed within the head 1a. The inner housing 1c is bolted to the bottom wall of the head 1a. The inner housing 1c is cylindrical with an open upper end. The side of the inner housing 1c facing the handle 1b has a clearance port 1c1 through which the water pump 2 passes. The inner end of the mounting bracket 4 extends into the clearance port 1c1. Two strip-shaped positioning ribs 1c2 are integrally formed on the edge of the clearance port 1c1. The two positioning ribs 1c2 are located on both sides of the clearance port 1c1 and correspond one-to-one with the locking protrusions 41 on both sides of the inner end of the mounting bracket 4. The sides of the locking protrusions 41 facing the outer end of the mounting bracket 4 abut against the corresponding positioning ribs 1c2. The open upper end of the inner housing 1c facilitates the installation of the water pump 2 within the shower head body 1. The inner shell 1c is made of plastic material. The outer peripheral surface of the inner shell 1c abuts against the inner peripheral surface of the head 1a. The inner shell 1c also has several circumferentially arranged strip holes 1c3, and the length direction of the strip holes 1c3 is arranged along the axial direction of the inner shell 1c.

[0050] like Figure 4 As shown, two pairs of strip-shaped guide protrusions 1b1 are integrally formed on the inner wall of the handle 1b near the head 1a. The length direction of each guide protrusion 1b1 is arranged along the axial direction of the handle 1b. One side of the inner end of the mounting bracket 4 is slidably engaged between one pair of guide protrusions 1b1, and the other side is slidably engaged between the other pair of guide protrusions 1b1. This design allows the inner end of the mounting bracket 4 to be guided during the insertion of the mounting bracket 4 into the handle 1b, enabling the mounting bracket 4 to be inserted into the handle 1b at a preset angle and trajectory. This ensures that the locking protrusion 41 can move smoothly to the locking position and achieve precise locking, thereby improving the ease of installation of the mounting bracket 4.

[0051] Example 2

[0052] This embodiment is basically the same as embodiment one in structure and principle, except that: Figure 8 As shown, two strip-shaped protrusions 1a1 are integrally formed on the inner circumferential surface of the head 1a. The inner end of the mounting bracket 4 extends between the two protrusions 1a1. The two protrusions 1a1 are correspondingly provided with locking protrusions 41 on both sides of the inner end of the mounting bracket 4. The side of the locking protrusion 41 facing the outer end of the mounting bracket 4 abuts against the corresponding protrusion 1a1. By integrally forming the protrusions 1a1 on the inner wall of the head 1a, the inner shell 1c structure can be eliminated, thus saving material. At the same time, the cooperation between the protrusions 1a1 and the locking protrusions 41 can achieve a stable locking connection, thereby more effectively preventing the mounting bracket 4 from moving outward and ensuring that the outer end of the mounting bracket 4 can always properly seal the port of the handle 1b.

[0053] Example 3

[0054] This embodiment is basically the same as embodiment one in structure and principle, except that: Figure 9 As shown, the inner shell 1c is cylindrical and open at the top. The side of the inner shell 1c facing the handle 1b has a clearance port 1c 1 through which the water pump 2 passes, but it does not have the strip hole 1c3 as in Embodiment 1.

[0055] Example 4

[0056] The structure and principle of this embodiment are basically the same as those of Embodiment 1. The difference is that the inner shell 1c is bonded to the head 1a with glue. Since the glue bonding method does not require additional connecting parts, it can make the internal structure of the shower head simpler and more compact, and reduce the manufacturing cost.

[0057] Example 5

[0058] This embodiment is basically the same as the first embodiment in terms of structure and principle. The difference is that the outer end wall 44 of the mounting bracket 4 is fixedly connected to the other end of the handle 1b by bolts. Specifically, a threaded hole can be machined on the end face of the other end of the handle 1b, and a bolt threaded into the threaded hole is passed through the outer end wall 44 of the mounting bracket 4. This structure does not require the setting of related structures such as the locking protrusion 41 and the positioning protrusion 1c2 to fix the mounting bracket 4, making the processing simpler, while also ensuring that the mounting bracket 4 is stably fixed in the handle 1b.

[0059] Example 6

[0060] The structure and principle of this embodiment are basically the same as those of Embodiment 1. The difference is that the inner end of the mounting bracket 4 is glued to the inner wall of the shower head body 1. Glue bonding has the advantages of being easy to manufacture and having low manufacturing cost.

[0061] Example 7

[0062] This embodiment is basically the same in structure and principle as Embodiment 1, except that the inner end of the mounting bracket 4 has a plate-like portion that abuts against the inner bottom wall of the head 1a. Bolts pass through this plate-like portion and connect to the inner bottom wall of the head 1a, thereby fixing the mounting bracket 4 inside the handle 1b. Alternatively, the inner end of the mounting bracket 4 can be fixedly connected to the inner wall of the handle 1b by bolts.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0064] Although this document frequently uses terms such as 1. shower head body; 1a. head; 1a1. protrusion; 1a2. water outlet; 1b. handle; 1b1. guide ridge; 1c. inner shell; 1c1. clearance opening; 1c2. positioning rib; 1c3. strip hole; 1c4. positioning post; 1c5. positioning notch; 2. water pump; 3. battery; 4. mounting bracket; 41. locking protrusion; 42. battery mounting slot; 43. water inlet; 5. top cover; 6. water outlet pipe; 7. water inlet pipe; 8. water outlet cavity; 9. water outlet panel, the possibility of using other terms is not excluded.
