Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and more specifically, to a fluid flow regulation device, a cleaning system for a toilet, and a toilet. Background Technology

[0002] With the increasing popularity and acceptance of smart toilets, people's pursuit of smart toilets is no longer limited to whether the product has relevant functions. Better product functions and user experience have gradually become important reference points for consumers when making a purchase.

[0003] The cleaning function is a fundamental and core feature of smart toilets. This function requires water pressure, typically provided by tap water pipes. The cleaning intensity is controlled by adjusting the water flow. To enhance comfort, most manufacturers incorporate an air pump into the water system, introducing air into the cleaning flow to improve both cleaning power and comfort.

[0004] However, because the water flow from the piped water supply is continuous, the cleaning process is essentially a constant stream of cleaning water. While this achieves the goal of cleaning, the lack of water pressure variation during the cleaning process can cause numbness and discomfort on the skin due to prolonged direct rinsing. Therefore, in today's market that prioritizes user experience, comfort, and differentiation, making the cleaning function more user-friendly and interactive is a crucial area of ​​research and product enhancement for manufacturers. Utility Model Content

[0005] This utility model provides a fluid flow regulation device, a toilet cleaning system, and a toilet to solve the problem of poor cleaning comfort in current toilet cleaning devices.

[0006] An embodiment of this application provides a fluid flow regulation device, characterized in that it includes:

[0007] The mounting housing is equipped with an inlet channel and an outlet channel;

[0008] A deformable bladder is installed on the mounting shell. The deformable bladder includes a main bladder body with a flow cavity and a connecting part provided on one side of the main bladder body. The inlet channel and the outlet channel are both connected to the flow cavity. The water enters from the inlet channel, flows through the flow cavity, and then flows out from the outlet channel.

[0009] A driving mechanism is configured to connect to the connecting part to drive the connecting part to move periodically. The periodic movement of the connecting part causes the main bladder to deform periodically, thereby periodically changing the size of the flow cavity.

[0010] In one embodiment, the mounting housing includes a base and a cover fixed to the base; wherein,

[0011] The cover is provided with the water inlet channel and the water outlet channel;

[0012] The deformable bladder is installed between the cover and the base, and the opening of the flow cavity faces the cover so that the inlet channel and the outlet channel lead to the opening. The connecting part is located on the side of the main bladder opposite to the opening.

[0013] In one embodiment, the base is provided with a positioning groove adapted to the deformable bladder, the cover is provided with an annular sealing groove, and the deformable bladder is provided with an annular sealing part on the side facing the cover. The deformable bladder is positioned in the positioning groove, and the cover seals the opening by cooperating with the annular sealing part and the annular sealing groove.

[0014] In one embodiment, one of the inlet channel and the outlet channel faces the opening, while the other is inclined relative to the opening.

[0015] In one embodiment, the driving mechanism is configured to drive the connecting portion to move in the direction toward the opening and away from the opening.

[0016] In one embodiment, the connecting part is a columnar structure with an annular flange arranged circumferentially on the columnar structure. The driving component of the driving mechanism is provided with a connecting hole. The connecting part is configured to be inserted into the connecting hole for connection. The annular flange passes through one end of the connecting hole to the other end of the connecting hole to prevent the connecting part from coming out of the connecting hole.

[0017] In one embodiment, the drive mechanism includes a motor, an eccentric wheel connected to the motor, and a swing member connected to the eccentric wheel. The motor is fixed to the mounting housing, and the connecting part is connected to the swing member so that the connecting part is driven to swing periodically by the swing member during the rotation of the eccentric wheel.

[0018] In one embodiment, the drive mechanism includes a motor, an eccentric rotor connected to the motor, and a swing arm eccentrically connected to the eccentric rotor, and further includes a slider that can slide relative to the mounting housing, the swing arm being connected to the slider, and the slider being connected to the connecting portion;

[0019] When the motor drives the eccentric rotor to rotate, the eccentric rotor drives the swing rod to swing, and the swing rod drives the slider to move back and forth. The back and forth movement of the slider causes the connecting part to move periodically.

[0020] In one embodiment, the driving frequency of the driving mechanism is set to be adjustable to adjust the deformation frequency of the deformable bladder.

[0021] Embodiments of this application also provide a toilet cleaning system, including an inlet pipe, an outlet pipe, a cleaning device, and a fluid flow regulation device as described above. The inlet pipe is connected to the inlet channel of the fluid flow regulation device, and the outlet channel of the fluid flow regulation device is connected to the cleaning device through the outlet pipe.

[0022] In one embodiment, the cleaning system further includes a control module electrically connected to the cleaning device and the fluid flow regulation device to control the cleaning device and the fluid flow regulation device;

[0023] The control module is configured to control the fluid flow regulation device to have a pulse working mode and a normal working mode. In the pulse working mode, the drive mechanism is controlled to drive the deformation bladder to produce periodic deformation. In the normal working mode, the drive mechanism is controlled to be in a non-working state.

[0024] Embodiments of this application also provide a toilet, including the cleaning system described above.

[0025] The technical solution provided in the embodiments of this application allows water entering from the inlet channel to flow out through the outlet channel after passing through the flow cavity. When the deformable bladder is driven by the drive mechanism to undergo periodic deformation, the size of the flow cavity changes periodically, resulting in periodic changes in the flow pressure and flow pattern of the water flowing through the flow cavity. This causes the water flowing out of the outlet channel to fluctuate at a certain frequency or to have a pulsating sensation. Using a fluid flow regulation device to supply water to the toilet's cleaning device allows the water flowing out of the cleaning device to pulsate at a certain frequency, enhancing user comfort during the cleaning process and making the toilet's cleaning function more user-friendly and interactive.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0044] Embodiments of this application provide a fluid flow regulation device 100, such as... Figures 1-8 The illustrated embodiment includes:

[0045] The mounting housing 10 is provided with an inlet channel 111 and an outlet channel 121;

[0046] The deformable bladder 4 is installed on the mounting shell 10. The deformable bladder 4 includes a main bladder body 41 with a flow cavity 411 and a connecting part 42 provided on one side of the main bladder body 41. The inlet flow channel 111 and the outlet flow channel 121 are both connected to the flow cavity 411. The water enters from the inlet flow channel 111, flows through the flow cavity 411, and flows out from the outlet flow channel 121.

[0047] The drive mechanism is configured to connect to the connecting part 42 to drive the connecting part 42 to move periodically. The periodic movement of the connecting part 42 causes the main bladder 41 to deform periodically, thereby periodically changing the size of the flow cavity 411.

[0048] The fluid flow regulation device 100 provided in this application can be used to supply water to the toilet cleaning device 200 (see reference). Figures 12-13 The fluid flow regulation device 100 supplies water to the toilet cleaning device 200, which can make the water flowing out of the cleaning device 200 pulsate at a certain frequency, which helps to enhance the user's comfort during the cleaning process, making the toilet cleaning function more user-friendly and the user experience more interactive.

[0049] Furthermore, since the fluid flow regulation device 100 provided in this application is an auxiliary flow pressure regulation module in the toilet's cleaning water circuit system, mainly used for regulating the flow water pressure, setting the fluid flow regulation device 100 in the toilet's cleaning water circuit system will not affect the normal cleaning function of the smart toilet. For example, when the fluid flow regulation device 100 fails to work (the drive mechanism does not drive the deformation bladder 4 to deform), the flow chamber 411 only serves the function of flow passage and does not regulate the water pressure, and the toilet's cleaning device 200 outputs water normally; while when the fluid flow regulation device 100 is working, the water pressure can be regulated by the deformation of the deformation bladder 4 to generate pulsating water output.

[0050] In one embodiment, such as Figures 1-8 As shown, the mounting housing 10 includes a base 2 and a cover 1 fixed to the base 2; wherein, the cover 1 is provided with a water inlet channel 111 and a water outlet channel 121. Specifically, a water inlet connector 11 for connecting a water inlet pipe and a water outlet connector 12 for connecting a water outlet pipe can be provided on the cover 1, with the water inlet connector 11 forming the water inlet channel 111 and the water outlet connector 12 forming the water outlet channel 121.

[0051] In this embodiment, the deformable bladder 4 is installed between the cover 1 and the base 2, and the opening of the flow cavity 411 faces the cover 1, so that the water inlet channel 111 and the water outlet channel 121 on the cover 1 are connected to the opening of the flow cavity 411. The connecting part 42 of the deformable bladder 4 is provided on the side of the main bladder 41 away from the opening of the flow cavity 411.

[0052] In one embodiment, the base 2 is provided with a positioning groove 21 that matches the deformable bladder 4. The shape of the positioning groove 21 is basically consistent with the outline of the deformable bladder 4 so as to position the deformable bladder 4 on the base 2 through the positioning groove 21. The cover 1 is provided with an annular sealing groove. Figure 5 The illustration shows a deformable bladder 4 in one embodiment. An annular sealing portion 43 is provided on the side of the bladder 4 facing the cover 1. When the cover 1 is fixed to the base 2, the deformable bladder 4 is positioned in the positioning groove 21 of the base 2, and the cover 1 seals the opening of the flow cavity 411 through the annular sealing portion 43 cooperating with the annular sealing groove. That is, the base 2 and the cover 1 clamp and fix the deformable bladder 4, and the cover 1 seals the flow cavity 411, so that water flowing into the flow cavity 411 from the inlet channel 111 can only flow out from the outlet channel 121.

[0053] In one embodiment, one of the inlet channel 111 and the outlet channel 121 is directly opposite the opening of the flow cavity 411, while the other is inclined relative to the opening of the flow cavity 411. Figures 1-8In the example, the inlet channel 111 faces the opening of the flow chamber 411, and the outlet channel 121 is inclined relative to the opening. Alternatively, the outlet channel 121 can be positioned facing the opening of the flow chamber 411, while the inlet channel 111 is inclined. By positioning either the inlet channel 111 or the outlet channel 121 facing the opening of the flow chamber 411, it is beneficial to generate a better pulsation amplitude when the volume of the flow chamber 411 changes.

[0054] In one embodiment, the drive mechanism 5 is configured to drive the connecting part 42 to move toward the opening of the flow cavity 411 and away from the opening of the flow cavity 411. That is, the connecting part 42 drives the bottom of the flow cavity 411 to move up and down to change the volume of the flow cavity 411.

[0055] In one embodiment, the connecting portion 42 of the deformable bladder 4 is a columnar structure, such as... Figures 2-3 as well as Figure 5 As shown, the columnar structure is provided with an annular flange 421 arranged circumferentially, and the driving component of the driving mechanism 5 is provided with a connecting hole 531. The columnar structure is configured to be inserted into the connecting hole 531 for connection. The annular flange 421 passes through one end of the connecting hole 531 to the other end of the connecting hole 531 to prevent the connecting part 42 from disengaging from the connecting hole 531. This connection method is simple and convenient.

[0056] It is understandable that the structure of the connecting part 42 of the deformable capsule 4 for connecting with the driving component is not limited to a columnar structure, but can also be other suitable structural forms, as long as the driving component can connect with the connecting part 42 and drive the connecting part 42 to move.

[0057] Figures 1-4 In one embodiment, the drive mechanism 5 includes a motor 51, an eccentric wheel 52 connected to the motor 51, and a swing member 53 connected to the eccentric wheel 52. A connecting part 42 is connected to the swing member 53 so that the connecting part 42 is driven by the swing member 53 to swing periodically during the rotation of the eccentric wheel 52. The motor 51 is fixed to the mounting housing 10, and the eccentric wheel 52 and the swing member 53 are located in the receiving cavity of the mounting housing 10.

[0058] The oscillating component 53 can be installed by inserting it into the eccentric hole of the eccentric wheel 52. The oscillating component 53 is provided with a connecting hole 531, and the connecting part 42 is inserted into the connecting hole 531 for installation. During the periodic rotation of the oscillating component 53 driven by the eccentric wheel 52, the oscillating component 53 will drive the connecting part 42 to oscillate periodically, thereby causing the bottom of the flow cavity 411 to move up and down. Figure 3 This shows the state where the connecting part 42 moves upward, causing the volume of the flow cavity 411 to decrease. Figure 2 The diagram shows the state where the connecting part 42 moves downward, causing the volume of the flow cavity 411 to increase.

[0059] Figures 1-4In this embodiment, to facilitate the installation of various components, the end of the base 2 away from the cover 1 can also be connected to the extended housing 3. The base 2 and the extended housing 3 together form a receiving cavity, and the driving component connected to the connecting part 42 of the deformable bladder 4 can be located within this receiving cavity (e.g., Figures 3-4 The eccentric wheel 52 and the swing member 53, which serve as driving components, are located inside the receiving cavity. The deformable bladder 4 is mounted on the base 2, and the connecting part 42 extends into the receiving cavity and connects to the driving component.

[0060] In this embodiment, the cover 1, the base 2, and the extended housing 3 can be fixed together by multiple connecting snap rings 6, or they can be fixed by fasteners such as bolts.

[0061] exist Figures 6-8 In this embodiment, the drive mechanism 5 includes a motor 51, an eccentric rotor 54 connected to the motor 51, and a swing rod 55 eccentrically connected to the eccentric rotor 54. It also includes a slider 56 that can slide relative to the mounting housing 10. The swing rod 55 is connected to the slider 56, and the slider 56 is connected to the connecting part 42. When the motor 51 drives the eccentric rotor 54 to rotate, the eccentric rotor 54 drives the swing rod 55 to swing, thereby driving the slider 56 to slide back and forth. The back-and-forth sliding of the slider 56 causes the connecting part 42 to move periodically. A positioning groove 561 can be provided on the slider 56, and the protrusion on the connecting part 42 can be positioned within the positioning groove 561 to achieve connection with the slider 56.

[0062] In this embodiment, the mounting housing 10 includes a fixed seat 7 connected to the base 2. The fixed seat 7 is provided with a groove that cooperates with the slider 56. The slider 56 is configured to slide back and forth along the groove of the fixed seat 7.

[0063] Those skilled in the art will understand that the driving mechanism 5 used to drive the deformable bladder 4 to deform is not limited to the above-described structural form. For example, the driving mechanism 5 can be a cylinder, with the driving end of the cylinder connected to the connecting part 42 to drive the connecting part 42 to move linearly. It will also be understood that the mounting shell 10 is not limited to the structural form in the above embodiments and can be modified in various ways.

[0064] In some embodiments, the driving frequency of the drive mechanism 5 is set to be adjustable, so that the driving frequency of the drive mechanism 5 can be adjusted according to different usage frequency requirements, thereby adjusting the deformation frequency of the deformable bladder 4 and obtaining different water discharge effects. For example, Figure 1-8 In this embodiment, the driving frequency of the drive mechanism 5 can be changed by altering the rotational speed of the motor 51. When a cylinder is used as the drive mechanism 5, the extension and retraction frequency of the cylinder 5's telescopic rod can be changed.

[0065] Figure 9 This illustrates the pulsating water discharge state when the drive mechanism 5 operates at a first drive frequency according to one embodiment of this application. Figure 10 This illustrates the pulsating water discharge state when the drive mechanism 5 operates at a second drive frequency according to one embodiment of this application. Figure 11 The illustration shows the pulsating water discharge state when the drive mechanism 5 operates at a third drive frequency according to one embodiment of this application. Different pulsating water discharge effects can be obtained by changing the drive frequency of the drive mechanism 5.

[0066] Furthermore, because the flow cavity 411 changes under the drive of external force, the cavity outputs corresponding pressure changes during compression and recovery. When the cavity is compressed, the fluid passing through the flow cavity 411 experiences a secondary pressurization on top of its original flow pressure. The magnitude of this secondary pressurization depends on the extent of compression of the flow cavity 411. A larger compression deformation of the flow cavity results in a larger secondary increase and a more pronounced frequency of flow pressure changes. Therefore, the appropriate cavity deformation range during deformation can be designed according to usage requirements. In some embodiments, the compressed volume of the flow cavity 411 can be set to 50%-80% of its uncompressed volume, and the flow pressure regulation effect within this compression range is better.

[0067] The variation range of the flow chamber 411 can be designed according to the required water pulse intensity. Specifically, the variation range of the flow chamber 411 can be changed by setting the movement amplitude of the connecting part 42, and the variation range of the flow chamber 411 can be adjusted by adjusting the movement amplitude of the connecting part 42.

[0068] Embodiments of this application also provide a toilet cleaning system, such as... Figure 12 and Figure 13 As shown, it includes an inlet pipe 500, an outlet pipe 500, a cleaning device 200, and a fluid flow regulation device 100 as described above. The inlet pipe 500 is connected to the inlet channel 111 of the fluid flow regulation device 100, and the outlet channel 121 of the fluid flow regulation device 100 is connected to the cleaning device 200 through the outlet pipe 600.

[0069] In one embodiment, the cleaning system may further include a water supply module 300, which is connected to a water inlet pipe 500 to supply water to the fluid flow regulation device 100. A heating module 700 may also be provided between the water supply module 300 and the fluid flow regulation device 100. The water supplied by the water supply module 300 first flows into the heating module 700 for heating, and then the heated water flows through the fluid flow regulation device 100 and enters the cleaning device 200.

[0070] In one embodiment, the cleaning system may further include a control module 400, which is electrically connected to the cleaning device 200 and the fluid flow regulation device 100 to control the cleaning device 200 and the fluid flow regulation device 100.

[0071] The control module 400 can be configured to control the fluid flow regulation device 100 to have a pulse working mode and a normal working mode. In the pulse working mode, the control drive mechanism 5 drives the deformable bladder 4 to produce periodic deformation. In the normal working mode, the control drive mechanism 5 is in a non-working state. When the drive mechanism 5 is in a non-working state, the fluid flow regulation device 100 is used for overcurrent, and the cleaning device 200 outputs a non-pulsating water flow. In addition, since the drive frequency of the drive mechanism 5 is set to be adjustable, in some embodiments, the pulse working mode of the fluid flow regulation device 100 can be set to have multiple levels, each level corresponding to a different drive frequency of the drive mechanism 5. The pulse frequency can be adjusted by adjusting the level.

[0072] The control module 400 can be configured to control the cleaning device 200 to have multiple cleaning functions, such as posterior wash, feminine wash, and functional wash water spray.

[0073] When this cleaning system is applied to a toilet, a control panel connected to the control module 400 can be equipped with various buttons or touch keys to control the fluid flow regulation device 100 and the cleaning device 200 respectively. The control panel allows selection of one of the cleaning functions of the cleaning device 200, such as posterior wash, feminine wash, or functional wash with water spray. Based on this cleaning function, a pulse working mode or a normal working mode can be selected, and the frequency level of the pulse working mode can also be chosen. This allows for multi-dimensional and multi-mode cleaning selection.

[0074] Embodiments of this application also provide a toilet, including the cleaning system described above.
