Description

Technical Field

[0001] This utility model relates to the field of bathroom cleaning technology, and in particular to a bidet device. Background Technology

[0002] A bidet is a portable cleaning device used to rinse the genitals or buttocks. This device is particularly useful for personal hygiene, especially in situations where convenient bathing is not available, such as while traveling, camping, or in public restrooms with poor hygiene. It is typically designed to be simple, easy to use, and portable.

[0003] There are several types of bidets currently available. For example, some use an electric water pump, but the main problem with these is that they require battery power and cannot function without electricity. Others use a manually squeezed soft bottle to spray water, but their main drawbacks are intermittent spraying and the need for physical exertion. Still others use air pressure to spray water, but these require frequent pumping and also suffer from intermittent spraying and the need for physical exertion. Utility Model Content

[0004] The present invention provides a bidet device that solves the technical problems of traditional bidets, such as the need for power supply, intermittent water spraying, and the consumption of physical strength.

[0005] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides a bidet, the bidet including a sleeve, a spray washing assembly, a piston, a tension spring, and a button. The top of the sleeve has an inlet and outlet. The spray washing assembly is movably disposed on the top of the sleeve. The piston is disposed inside the sleeve and is axially movable. One end of the tension spring abuts against the inlet and outlet, and the other end of the tension spring is connected to the piston. The button is disposed on the sleeve and passes through the outer wall of the sleeve to act on the piston. The button has a first state of locking the piston and a second state of releasing the piston.

[0006] In some embodiments, the outer surface of the piston has a toothed surface extending along the axial direction and a smooth surface extending along the axial direction. The toothed surface has a plurality of convex tooth structures arranged sequentially along the axial direction. When the button is in the released state, the piston is engaged between adjacent convex tooth structures to restrict the movement of the piston. When the button is in the pressed state, the piston disengages from the adjacent convex tooth structures to achieve axial movement.

[0007] In some embodiments, the button includes a button holder disposed at the bottom of the sleeve, and a button body is provided between the button holder and the sleeve. The button body has a mating opening, and the button body is fitted onto the piston through the mating opening. When the button is in a first state, the edge of the mating opening can be engaged between adjacent tooth structures. When the button is in a second state, the edge of the mating opening disengages from the adjacent tooth structures.

[0008] In some embodiments, the button further includes a reset spring, the end of the button body has a guide post, one end of the reset spring is sleeved on the guide post, and the other end of the reset spring abuts against the inner wall of the button fixing bracket; when the button body is pressed, the reset spring is compressed, and when the button body is released, the reset spring causes the button body to reset.

[0009] In some embodiments, the bidet further includes a handle connected to the end of the piston away from the spray assembly, the handle being located outside the sleeve; the handle can drive the piston to rotate to adjust the position of the piston's toothed and smooth surfaces, so that the piston is always disengaged from the adjacent toothed structure to achieve continuous axial movement.

[0010] In some embodiments, the spray assembly includes a nozzle head and a nozzle rod, the nozzle head being movably disposed at the top end of the sleeve, the nozzle rod being rotatably inserted into the nozzle head, and the end of the nozzle rod extending out of the nozzle head having a spray hole.

[0011] In some embodiments, the nozzle head has an opening at the top, a channel below the opening, a protrusion on the inner wall of the channel, and a groove on the outer wall of the nozzle movable rod, the groove engaging with the protrusion; wherein the channel is in communication with the inlet and outlet.

[0012] In some embodiments, the top of the sleeve has a fixed bracket, one end of which is movably connected to the nozzle head, and the other end of which extends into the sleeve and bends towards the center within the sleeve to form the inlet and outlet.

[0013] In some embodiments, the portion of the other end of the fixing bracket extending into the sleeve has a first sealing ring between it and the inner wall of the sleeve; and / or the outer wall of the piston near the end of the spray assembly has a second sealing ring between it and the inner wall of the sleeve.

[0014] In some embodiments, the end of the tension spring is fixed to the interior of the piston by a screw, and the end of the tension spring has a constricted structure so that it can be locked into the head of the screw; the screw is disposed in a blind hole inside the piston; wherein, the end of the tension spring is the end of the tension spring closer to the handle.

[0015] Compared with the prior art, the cleansing device of this utility model has at least the following beneficial effects:

[0016] The bidet provided by this utility model includes a sleeve, a spray washing assembly, a piston, a tension spring, and a button. The top of the sleeve has an inlet and outlet. The spray washing assembly is movably disposed on the top of the sleeve. The piston is disposed inside the sleeve and can move axially. One end of the tension spring abuts against the inlet and outlet, and the other end of the tension spring is connected to the piston. The button is disposed on the sleeve and passes through the outer wall of the sleeve to act on the piston. The button has a first state of locking the piston and a second state of releasing the piston.

[0017] In practical use, firstly, the spray assembly is disassembled, and the piston is pulled to the bottom of the sleeve to maximize the space inside the sleeve. During this process, the tension spring stores elastic potential energy. Then, water is added to the sleeve through the inlet and outlet at the top, and the spray assembly is installed. Pressing the button puts the device in its second state, allowing the piston to release. The piston then moves under the action of the tension spring, causing water in the sleeve to spray out through the spray assembly. Releasing the button puts the device in its second state, where it engages with the piston, fixing the piston and preventing water from spraying out. This embodiment achieves the function of spraying water when the button is pressed and stopping the spray when the button is released. Compared to traditional technology, the bidet provided in this embodiment uses mechanical energy storage via a tension spring instead of electric drive, eliminating the need for batteries or external power sources and completely solving the limitation of use in environments without electricity. The spring release provides stable thrust, and the piston's uniform movement ensures continuous water output, avoiding the intermittent problem of manual squeezing. Furthermore, users only need to pull the piston once to store energy, and the subsequent water spraying is automatically completed by the spring, without the need for repeated air pumping or force application.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] This embodiment provides a body wash device, such as Figures 1-10 As shown, the bidet includes a sleeve 1, a spray washing assembly 2, a piston 3, a tension spring 4, and a button 5. The top of the sleeve 1 has an inlet / outlet 11. The spray washing assembly 2 is movably disposed on the top of the sleeve 1. The piston 3 is disposed inside the sleeve 1 and can move axially. One end of the tension spring 4 abuts against the inlet / outlet 11, and the other end of the tension spring 4 is connected to the piston 3. The button 5 is disposed on the sleeve 1 and passes through the outer wall of the sleeve 1 to act on the piston 3. The button 5 has a first state of locking the piston 3 and a second state of releasing the piston 3.

[0037] The sleeve 1 has a generally hollow cylindrical structure, serving as a water storage container and structural body. It has an inlet / outlet 11 at the top for water injection and connection to the spray assembly 2. The internal space accommodates piston movement. The spray assembly 2 is movably mounted on the top of the sleeve 1, controlling the direction of water flow. In this embodiment, the spray assembly 2 is detachable, facilitating water injection after disassembly and forming a closed water system after installation. The piston 3 compresses the internal space of the sleeve 1 by axial movement, forcing water into the spray assembly 2. The tension spring 4 stores elastic potential energy, providing a continuous driving force to propel the piston. One end of the tension spring 4 is fixed to the inlet / outlet 11, and the other end is connected to the piston 3. It stores energy when stretched and converts it into piston kinetic energy when released. The button 5 penetrates the outer wall of the sleeve 1 and engages with the piston 3. In the first state (released), the piston 3 is locked; in the second state (pressed), the constraint is released, triggering the tension spring to drive the piston 3.

[0038] In practical use, firstly, the spray washing assembly 2 is disassembled, and simultaneously, the piston 3 is pulled to the bottom of the sleeve 1, maximizing the space inside the sleeve 1. During this process, the tension spring 4 stores elastic potential energy. Then, water is added to the sleeve 1 through the inlet / outlet 11 at the top of the sleeve 1, and the spray washing assembly 2 is installed. Pressing button 5 puts it in its second state, allowing the piston 3 to be released. The piston 3 then moves under the action of the tension spring 4, causing the water inside the sleeve 1 to spray out through the spray washing assembly 2. Releasing button 5 puts it in its second state, where it engages with the piston 3, fixing the piston 3 and preventing the water inside the sleeve 1 from being sprayed out through the spray washing assembly 2. This embodiment achieves the function of spraying water when button 5 is pressed and stopping water spraying when button 5 is released. In other words, the workflow of the body wash device provided in this embodiment is divided into three stages. The first stage is water preparation, specifically: disassembling the spray assembly 2, pulling the piston 3 to the bottom of the sleeve 1, at which point the tension spring 4 stores energy, water is injected into the sleeve 1, and the spray assembly 2 is reinstalled. The second stage is starting the water spray, specifically: pressing button 5, which is in the second state described above, contacting the piston 3's limit position, causing the tension spring 4 to contract and drive the piston 3 upwards, pressurizing the water in the sleeve 1, and then the water flows through the spray assembly 2 to form a spray. The third stage is stopping the water spray, releasing button 5, which is in the first state, locking the piston 3, and interrupting the water flow. The second and third stages can be performed alternately to achieve intermittent water spraying.

[0039] Compared to traditional technologies, the bidet provided in this embodiment uses a tension spring mechanical energy storage system instead of electric drive, eliminating the need for batteries or external power sources and completely solving the limitations of use in environments without electricity. The spring release provides stable thrust, and the piston's uniform movement ensures a continuous water flow, avoiding the intermittent problems associated with manual squeezing. Furthermore, the user only needs to pull the piston once to store energy; subsequent water spraying is automatically completed by the spring, eliminating the need for repeated air pumping or force application.

[0040] In a specific embodiment, such as Figure 3 and Figure 10 As shown, the outer surface of the piston 3 has a toothed surface 31 extending along the axial direction and a smooth surface 32 extending along the axial direction. The toothed surface 31 has a plurality of convex tooth structures arranged sequentially along the axial direction. When the button 5 is in the released state, the piston 3 is engaged between adjacent convex tooth structures to restrict the movement of the piston 3. When the button 5 is in the pressed state, the piston 3 disengages from the adjacent convex tooth structures to achieve axial movement. The toothed surface 31 and the smooth surface 32 enclose the entire outer surface of the piston 3.

[0041] The toothed surface 31, through its axially arranged convex tooth structure (such as sawtooth or trapezoidal teeth), cooperates with the button 5 to fix the piston 3 and prevent the piston from moving when the tension spring 4 returns. Furthermore, the spacing between adjacent convex tooth structures corresponds to the fixed stroke of a single movement of the piston 3, ensuring controllable water release with each press. The toothed surface 31 is located on one side of the outer wall of the piston 3 (e.g., a semi-circular area), with multiple convex teeth evenly distributed on its surface; the tooth spacing can be designed according to water spray requirements. The smooth surface 32 is located on the other side of the outer wall of the piston 3 (symmetrically distributed with the toothed surface 31), with a smooth surface without protrusions, ensuring smooth sliding of the piston 3. The smooth surface 32 extends from the top to the bottom of the piston 3, parallel to the toothed surface 31, forming a "half-toothed, half-smooth" outer wall structure of the piston 3.

[0042] In a specific embodiment, such as Figure 8 and Figure 9 As shown, the button 5 includes a button fixing bracket 51, which is disposed at the bottom of the sleeve 1. A button body 52 is located between the button fixing bracket 51 and the sleeve 1. The button body 52 has a mating opening 53, and the button body 52 is fitted onto the piston 3 through the mating opening 53. When the button 5 is in a first state, the edge of the mating opening 53 can be engaged between adjacent tooth structures. When the button 5 is in a second state, the edge of the mating opening 53 disengages from the adjacent tooth structures.

[0043] The button holder 51 is fixed to the bottom of the sleeve 1, serving as a support base for the button 5 and ensuring the stability of the movement trajectory of the button body 52. ​​The button holder 51 constrains the pressing direction of the button body 52, preventing deviation or rotation. The button body 52 is a movable part located between the button holder 51 and the sleeve 1, and is the operating end that the user directly presses. The mating opening 53 is a through hole on the button body 52, fitted onto the outer surface of the piston 3, and matches the convex tooth structure of the tooth surface 31. When the button 5 is in the first state (released), the edge of the mating opening 53 is embedded in the gap between adjacent convex teeth, forming a rigid block and fixing the position of the piston 3. When the button 5 is in the second state (pressed), the mating opening 53 shifts laterally, and the edge disengages from the convex teeth, releasing the constraint on the piston 3.

[0044] During the fixing phase of piston 3, the edge of the mating port 53 is embedded between adjacent protrusions of piston tooth surface 31. The contraction force of tension spring 4 attempts to pull piston 3 upward, but the protrusions of piston tooth surface 31 are blocked by the edge of mating port 53, forming a reaction force balance. At this time, the water pressure inside sleeve 1 cannot push the piston, and the water flow is interrupted. During the release phase of piston 3, the user presses button body 52, which moves laterally along the guide groove of button fixing bracket 51, causing mating port 53 to shift synchronously. The edge of mating port 53 disengages from the protrusion area of ​​tooth surface 31 and moves to the position corresponding to piston smooth surface 32. Smooth surface 32 is a smooth surface, and there are no protrusions blocking the edge of mating port 53 in this area, so the contraction force of tension spring 4 can freely pull piston 3 upward. Piston 3 moves at a constant speed along the axial direction of sleeve 1, compressing the internal water storage, and the water flow is continuously sprayed out through spray washing assembly 2. As long as the button is pressed, the mating port 53 remains in the area of ​​the smooth surface 32, and the piston movement is unrestricted; after the button is released, the reset spring 54 returns the button to its original position, and the mating port 53 re-engages with the toothed surface, locking the piston 3.

[0045] In a specific embodiment, such as Figure 6 , Figure 8 as well as Figure 9 As shown, the button 5 also includes a reset spring 54. The end of the button body 52 has a guide post 55. One end of the reset spring 54 is sleeved on the guide post 55, and the other end of the reset spring 54 abuts against the inner wall of the button fixing bracket 51. When the button body 52 is pressed, the reset spring 54 is compressed. When the button body 52 is released, the reset spring 54 causes the button body 52 to reset.

[0046] The return spring 54, after the user releases the button body 52, pushes the button 5 back to its initial position through elastic restoring force, ensuring that the mating port 53 re-engages with the tooth gap of the piston tooth surface 31. The guide post 55 restricts the movement path of the button body 52, ensuring that it moves in a straight line when pressed, avoiding offset or rotation that could cause jamming. It also provides central support for the return spring 54, preventing it from bending laterally or falling out of position. The guide post 55 is a columnar protrusion, integrally formed with the button body 52, extending vertically from the end of the button, and its length is slightly shorter than the natural length of the return spring 54.

[0047] When button 5 is pressed, the reset spring 54 is compressed as the guide post 55 moves, the spring coil spacing decreases, and elastic potential energy is stored. After button 5 is released, the elastic potential energy of the reset spring 54 is converted into kinetic energy, which pushes the button body 52 to move in the opposite direction along the guide post 55 and return to the initial position. During this process, the linear constraint of the guide post 55 ensures that the button returns to its precise position and avoids misalignment between the mating port 53 and the tooth surface 31.

[0048] In a specific embodiment, the bidet also includes a handle 6, which is connected to the end of the piston 3 away from the spray washing assembly 2. The handle 6 is located outside the sleeve 1. The handle can drive the piston 3 to rotate, so as to adjust the position of the tooth surface 31 and the smooth surface 32 of the piston 3, so that the piston 3 is always disengaged from the adjacent tooth structure to achieve continuous axial movement.

[0049] The handle 6 can drive the piston 3 to rotate. By rotating the piston 3, the position of the toothed surface 31 and the smooth surface 32 relative to the mating port 53 of the button 5 is changed, realizing the function switch between "intermittent water spraying" and "continuous water spraying". In continuous mode, the piston 3 can move automatically throughout the entire process without repeatedly pressing the button 5, which significantly reduces the operating load.

[0050] In the "intermittent spray" mode, the toothed surface 31 is aligned with the mating port 53, and the protruding tooth structure is embedded in the edge of the mating port. When the button 5 is pressed, the piston is briefly released and immediately locked after being released. In the "continuous spray" mode, the user rotates the handle 6, which drives the piston 3 to rotate, so that the smooth surface 32 is aligned with the mating port 53. Since the smooth surface 32 has no protruding teeth, the edge of the mating port 53 is unobstructed, and the piston 3 can move freely axially under the action of the tension spring 4 without relying on button operation.

[0051] In a specific embodiment, the spray washing assembly 2 includes a nozzle head 21 and a nozzle movable rod 22. The nozzle head 21 is movably disposed at the top end of the sleeve 1, and the nozzle movable rod 22 is rotatably inserted into the nozzle head 21. The end of the nozzle movable rod 22 extending out of the nozzle head 21 has a spray hole 23.

[0052] The nozzle head 21 is generally a hollow conical or cylindrical shell. Its bottom is connected to the inlet / outlet 11 at the top of the sleeve 1 via threads or snaps. The top has a rotating interface for inserting the nozzle rod 22. The nozzle head 21 guides the pressurized water flow within the sleeve 1 into the internal channel of the nozzle rod 22. The nozzle rod 22 is generally a slender hollow tube. One end is inserted into the nozzle head 21 and rotatably sealed thereto, while the other end extends out of the nozzle head 21 and has a spray hole 23. During operation, the piston 3 is driven upwards by the tension spring 4, compressing the water within the sleeve 1. The water flows through the inlet / outlet 11 into the cavity of the nozzle head 21, then into the internal flow channel of the nozzle rod 22, flowing along the rod towards the spray hole 23.

[0053] In a specific embodiment, the top of the nozzle head 21 has an opening 24, the lower part of the opening 24 has a channel 25, the inner wall of the channel 25 has a protrusion 26, the outer wall of the nozzle movable rod 22 has a groove 27, and the groove 27 cooperates with the protrusion 26; wherein, the channel 25 can communicate with the inlet and outlet 11.

[0054] During operation, piston 3 is driven upward by tension spring 4. The water inside sleeve 1 is pressurized and enters channel 25 through inlet / outlet 11. The pressurized water flows from channel 25 to opening 24 and then into the internal flow channel of nozzle actuator 22. The water flow reaches nozzle 23 through the internal flow channel of nozzle actuator 22, forming a water column or atomized spray depending on the nozzle type (single or multiple holes).

[0055] Furthermore, by rotating the nozzle movable rod 22, the groove 27 slides along the protrusion 26, enabling fine adjustment of the angle of the nozzle 23.

[0056] In a specific embodiment, the top of the sleeve 1 has a fixed bracket 7, one end of the fixed bracket 7 is movably connected to the nozzle head 21, and the other end of the fixed bracket 7 extends into the sleeve 1 and bends towards the center inside the sleeve 1 to form the inlet / outlet 11.

[0057] The fixed bracket 7 serves as a rigid connection between the nozzle head 21 and the sleeve 1, ensuring that the nozzle head remains stable when adjusting the angle and preventing loosening or detachment due to water pressure or external operation. The portion of the fixed bracket 7 extending into the sleeve 1 provides a positioning reference for the inlet and outlet ports 11, maintaining the axial alignment of components such as the piston 3 and tension spring 4, and preventing mechanical movement deviation.

[0058] In a specific embodiment, the portion of the other end of the fixing bracket 7 extending into the sleeve 1 has a first sealing ring 71 between it and the inner wall of the sleeve 1. A small gap may exist between the portion of the fixing bracket 7 extending into the sleeve 1 and the inner wall of the sleeve. The first sealing ring 71 fills this gap, preventing water from leaking from the inside of the sleeve 1 to the outside, ensuring that water only enters the nozzle head 21 through the inlet / outlet 11.

[0059] In a specific embodiment, a second sealing ring 33 is provided between the outer wall of the piston 3 near the end of the spray assembly 2 and the inner wall of the sleeve 1. When the piston 3 moves axially within the sleeve 1, the second sealing ring 33 fits tightly against the inner wall of the sleeve 1, preventing water from leaking backwards around the piston 3 and ensuring that the full pressure of the piston 3 compressing the water flow is applied to the spray assembly 2.

[0060] In a specific embodiment, the end of the tension spring 4 is fixed to the inside of the piston 3 by a screw 8, and the end of the tension spring 4 has a constricted structure so that it can be locked in the head of the screw 8; the screw 8 is disposed in a blind hole inside the piston 3; wherein, the end of the tension spring 4 is the end of the tension spring 4 near the handle 6.

[0061] In this embodiment, the constriction structure refers to a specially processed, narrowed opening design at the end of the tension spring 4 near the handle 6, making its opening diameter smaller than the diameter of the screw head 8. When the screw 8 is inserted into the constriction structure at the end of the tension spring 4, the head of the screw 8 is stuck inside the constriction structure and cannot be removed. This design achieves a secure connection between the tension spring 4 and the screw 8, preventing loosening due to repeated stretching or vibration, while eliminating the need for additional fasteners and simplifying the assembly process.

[0062] In addition, the blind hole inside the piston is a hole structure that is open on one side and closed on the other. It can secure the screw 8 and also serves a waterproof function. The blind hole does not penetrate the entire piston 3, and the closed end forms a barrier to prevent water from flowing through the hole into other areas inside the piston 3.

[0063] The bidet provided in this embodiment uses a tension spring as the power source for water spraying. It does not require electricity; simply pull the tension spring to a certain height. There are two spraying modes: one is an intermittent spraying mode where water is sprayed when the button is pressed and stopped when the button is released; the other is a continuous spraying mode where water is sprayed continuously for cleaning after the handle is rotated.

[0064] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
