Technical Field

[0001] The invention relates to a toilet brush device. Background Art

[0002] Existing toilet brush devices generally consist of a toilet brush and a brush holder. The toilet brush includes a handle with a connector below the handle, which is equipped with a brush head for cleaning the toilet bowl. However, these devices also suffer from disadvantages: they lack cleaning liquid. Currently, the cleaning liquid is typically poured into the toilet bowl, but this is diluted by the water in the bowl, leaving the cleaning effect unsatisfactory. No existing toilet brush device can store cleaning liquid and release it during use. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings of the existing toilet brush device, the present invention provides a toilet brush device that can store cleaning liquid and release the cleaning liquid when in use.

[0004] The present invention solves the technical problem by providing a toilet brush device comprising a toilet brush, wherein the toilet brush comprises a brush handle, a brush head, and a brush holder, wherein the brush holder comprises a cleaning liquid chamber for holding a cleaning liquid and a brush head chamber for placing the brush head of the toilet brush;

[0005] The brush head has a liquid storage cavity for storing cleaning liquid, and a slow-release mechanism is provided in the liquid storage cavity. After the brush head is placed in the brush head cavity, the liquid storage cavity is lower than the bottom surface of the cleaning liquid cavity;

[0006] The brush holder is provided with a liquid inlet pipeline, and a valve device is provided on the liquid inlet pipeline. The first end of the liquid inlet pipeline is connected to the cleaning liquid chamber. After the brush head is placed in the brush head chamber, the second end of the liquid inlet pipeline is connected to the liquid storage chamber. After the valve device is opened, the cleaning liquid in the cleaning liquid chamber enters the liquid storage chamber under the action of the liquid level difference;

[0007] The brush handle is provided with an air blowing device for blowing air into the liquid storage cavity, and the brush head is provided with a release port. After the air blowing device blows air into the liquid storage cavity, the cleaning liquid in the liquid storage cavity is released to the outside of the brush head through the slow-release mechanism and the release port under the action of air pressure.

[0008] Furthermore, the brush head and the brush handle are separately provided; the brush handle is provided with a motor for driving the brush head to rotate, a power supply for powering the motor, and a circuit board for controlling the operation of the motor, and the power supply and the motor are respectively connected to the circuit board.

[0009] Furthermore, the liquid storage chamber is connected to the brush head, so that when the motor drives the brush head to rotate, the liquid storage chamber rotates accordingly. Alternatively, the liquid storage chamber is provided separately from the brush head, so that when the motor drives the brush head to rotate, the liquid storage chamber remains stationary.

[0010] Furthermore, the valve device is a solenoid valve provided on the liquid inlet pipeline; or the valve device is a manual valve provided on the liquid inlet pipeline, the manual valve being connected to a drive mechanism for opening and closing the manual valve. Alternatively, the valve device is a lotion pump provided at the second end of the liquid inlet pipeline. When the brush head is placed in the brush head cavity, the lotion pump is pressed downward by the brush head, thereby opening the lotion pump. When the brush head is removed, the lotion pump automatically closes due to its own elastic force.

[0011] When the motor drives the brush head to rotate, the liquid storage chamber rotates accordingly. A liquid inlet pipe is provided in the brush head below the liquid storage chamber. After the brush head is placed in the brush head chamber, the lower end of the liquid inlet pipe is connected to and contacts the lotion pump. The upper end of the liquid inlet pipe penetrates the liquid storage chamber. The slow-release mechanism is provided on the upper end of the liquid inlet pipe.

[0012] A liquid inlet hole is provided on the side wall of the liquid inlet pipe. When the brush head is not pressed down, the liquid inlet hole is located below the liquid storage cavity. After the brush head is pressed down a first distance, the liquid inlet hole is located in the liquid storage cavity. When the brush head is further pressed down, the lotion pump is pressed through the liquid inlet pipe, thereby opening the lotion pump. The cleaning liquid in the cleaning liquid cavity flows into the liquid storage cavity through the liquid inlet pipeline, the lotion pump, the liquid inlet pipe, and the liquid inlet hole on the liquid inlet pipe;

[0013] After the brush head is no longer pressed, the toilet brush rises, and the liquid inlet hole on the liquid inlet pipe is located below the liquid storage cavity again.

[0014] Furthermore, a first sealing ring is provided at the upper end of the liquid inlet pipe; the first sealing ring is located in the liquid storage chamber, and a seal is formed between the first sealing ring and the bottom surface of the liquid storage chamber when the toilet brush is not pressed down, and the slow-release mechanism is provided on the first sealing ring.

[0015] Furthermore, a pressing portion is provided on the liquid inlet pipe, and a pressure-bearing portion is provided on the lotion pump. The pressing portion contacts the pressure-bearing portion. After the toilet brush is pressed down to a first distance, it continues to press the pressing portion. The pressing portion presses the pressure-bearing portion downward, thereby pressing the lotion pump.

[0016] Furthermore, the pressing portion is arranged on the outer surface of the liquid inlet pipe.

[0017] Furthermore, the pressing part is provided with a convex shoulder corresponding to the liquid storage cavity. After the brush head is pressed down until the liquid storage cavity contacts the convex shoulder, it continues to press down to drive the pressing part to press down, and then push the pressure-bearing part to press down.

[0018] Furthermore, the pressing portion has a receiving cavity, and a first elastic device is provided in the receiving cavity. The elastic force of the first elastic device is smaller than the elastic force of the lotion pump itself. The lower end of the first elastic device presses against the receiving cavity, and the upper end of the first elastic device presses against the liquid storage cavity. Under the action of the first elastic device, the liquid storage cavity has an upward tendency.

A second elastic member is provided in the flow chamber to act on the lifting tube, and the elastic force of the second elastic member is less than the elastic force of the lotion pump itself. Under the action of the second elastic member, the lifting tube is in a low position, at which time the inner hole is located below the flow chamber, and the flow chamber and the lifting tube are sealed. When releasing the cleaning liquid, the cleaning liquid in the liquid storage chamber is released into the lifting tube through the slow-release mechanism under the action of air pressure and eventually flows out of the brush head.

[0022] When the brush head is pressed down, the lotion pump is connected to the lifting tube and pushes the lifting tube upward. At this time, the seal between the flow chamber and the lifting tube is released, and the inner hole is located in the flow chamber; when the lifting tube further rises to touch the upper end surface of the rotating member, it continues to press down the brush head, and the elastic force of the lotion pump itself is overcome and it is pressed downward, thereby opening the lotion pump.

[0069] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0070] Example 1, refer to Figure 1-17 A toilet brush device includes a toilet brush, wherein the toilet brush includes a brush handle 1, a brush head 2, and a brush holder. The brush holder includes a cleaning liquid cavity 3 for holding cleaning liquid and a brush head cavity 4 for placing the brush head 2 of the toilet brush.

[0071] The brush head 2 has a liquid storage chamber 5 for storing cleaning liquid, and a slow-release mechanism is provided in the liquid storage chamber 5. After the brush head 2 is placed in the brush head chamber 4, the liquid storage chamber 5 is lower than the bottom surface of the cleaning liquid chamber 3, thereby generating a liquid level difference. Under the action of the liquid level difference, the cleaning liquid in the cleaning liquid chamber 3 can flow into the liquid storage chamber 5.

[0072] The brush holder is provided with a liquid inlet line 6, which is equipped with a valve device. The first end of the liquid inlet line 6 is connected to the cleaning liquid chamber 3. After the brush head 2 is placed in the brush head chamber 4, the second end of the liquid inlet line 6 is connected to the liquid storage chamber 5. When the valve device is opened, the cleaning liquid in the cleaning liquid chamber 3 enters the liquid storage chamber 5 due to the liquid level difference. The valve device can take various forms, such as a solenoid valve provided on the liquid inlet line 6; or a manual valve provided on the liquid inlet line 6, connected to a drive mechanism for driving its opening and closing. The manual valve can be a ball valve, a valve, etc. Another valve device will be described in detail below with reference to the accompanying drawings.

[0073] The brush handle 1 is provided with an air-inflating device for inflating air into the liquid storage chamber 5. The brush head 2 is provided with a release port 19, which is generally located on the bottom surface of the brush head 2. After the air-inflating device inflates air into the liquid storage chamber 5, the cleaning liquid in the liquid storage chamber 5 is released to the outside of the brush head 2 through the slow-release mechanism and the release port 19 under the action of air pressure. That is, the slow-release mechanism in the present invention is a mechanism with a slow-release port, which forces the release port to open when air pressure is applied to the cleaning liquid in the liquid storage chamber 5. In this embodiment, the slow-release mechanism is a flexible slow-release sheet 7, which can be made of rubber or silicone material. A slow-release slit 8 is provided on the slow-release sheet 7. The slow-release slit 8 can be a single slit or a cross-shaped slit. When unpressurized, the cleaning liquid will not leak from the slow-release slit 8. When pressurized, the slow-release slit 8 opens, thereby allowing the cleaning liquid to be released. Of course, the slow-release mechanism can also adopt an air pressure structure. For example, the slow-release mechanism is a duckbill valve. When not pressurized, the cleaning liquid will not leak from the duckbill valve. When air pressure is applied, the valve mouth of the duckbill valve opens, thereby realizing the release of the cleaning liquid.

[0074] In this embodiment, the brush head 2 is provided separately from the brush handle 1. The brush handle 1 houses a motor 9 for driving the brush head, a power supply 10 (typically a battery) for powering the motor 9, and a circuit board 11 for controlling the operation of the motor 9. The power supply 10 and the motor 9 are each connected to the circuit board 11. The motor 9 drives the brush head 2 to rotate, achieving a better cleaning effect when scrubbing the toilet.

[0075] In this embodiment, the liquid storage chamber 5 is also provided separately from the brush head 2, so that when the motor drives the brush head 2 to rotate, the liquid storage chamber 5 remains stationary, thereby preventing the cleaning liquid in the liquid storage chamber from being thrown out during the rotation of the liquid storage chamber 5. In this embodiment, the liquid storage chamber 5 is connected to the brush handle 1, thereby being fixed.

[0076] In this embodiment, the valve device is a lotion pump 12 provided at the second end of the liquid inlet pipe 6. After the brush head 2 is placed in the brush head cavity 4, the lotion pump 12 is pressed down by the brush head 2 so that the lotion pump 12 is opened. After the brush head 2 is removed, the lotion pump 12 automatically closes under the action of its own elastic force. The lotion pump 12 is a conventional technical means in the prior art. It has its own elastic force. When pressed downward by an external force, the lotion pump opens. When the external force is removed, the lotion pump automatically closes under the action of its own elastic force. For example, Chinese patents CN2371382Y, CN2371155Y, CN2493753Y, CN2497877Y, CN2508866Y, CN2533089Y, CN2509115Y, CN100537374C, and CN200948448Y all disclose the structure of lotion pumps. Searching for "lotion pump" on major search engines or on TikTok also provides detailed descriptions of the structure and working principle of lotion pumps. Ready-made lotion pump products can also be purchased by typing "lotion pump" on 1688.com, an Alibaba subsidiary.

[0077] In this embodiment, the specific way in which the cleaning liquid in the cleaning liquid chamber 3 enters the liquid storage chamber 5 and the specific way in which the cleaning liquid is released from the liquid storage chamber 5 is: the liquid storage chamber 5 has a rotating part 13, the upper part of the rotating part 13 is connected to the motor 9, and the lower part of the rotating part 13 is connected to the brush head 2, so that the motor 9 drives the brush head 2 to rotate through the rotating part 13. The rotating member 13 has an upper flow chamber 14 and a lower insertion chamber 1. A central hole is defined on the sidewall of the flow chamber 14. A lifting tube 16 is defined in the flow chamber 14 and the insertion chamber 15. The sustained-release tablet 7 covers the upper end of the lifting tube 16. The lifting tube 16 has an inner hole 17. A second elastic member 18 (generally in the form of a spring) is defined in the flow chamber 14 to act on the lifting tube 16. The elastic force of the second elastic member 18 is less than the elastic force of the lotion pump 12 itself. Under the action of the second elastic member 18, the lifting tube 16 is in a low position. At this time, the inner hole 17 is located below the flow chamber 14, and the flow chamber 14 and the lifting tube 16 are sealed. Since a middle hole is opened on the flow chamber 14, the cleaning liquid in the liquid storage chamber 5 flows into the flow chamber 14 through the middle hole. When the cleaning liquid is released, the cleaning liquid in the liquid storage chamber 5 is released to the lifting tube 16 through the slow-release slit 8 on the slow-release sheet 7 under the action of air pressure and finally flows out of the brush head 2 from the release port 19.

[0078] When the brush head 2 is pressed down, the lotion pump 12 is connected to the lifting tube 16 and pushes the lifting tube 16 upward. At this time, the seal between the flow chamber 14 and the lifting tube 16 is released, and the inner hole 17 is located in the flow chamber 14. When the brush head 2 is further pressed down, the lifting tube 16 further rises until it touches the upper end surface of the rotating member 13 and continues to press down the brush head 2. The elastic force of the lotion pump 12 itself is overcome and it is pressed down, thereby opening the lotion pump 12. The cleaning liquid in the cleaning liquid chamber 3 flows into the liquid storage chamber 5 through the liquid inlet pipeline 6, the lotion pump 12, the lifting tube 16, the inner hole 17 of the lifting tube, the flow chamber 14, and the middle hole on the flow chamber 14.

[0079] In this embodiment, a sealing step 20 is provided between the flow chamber 14 and the insertion chamber 15. A second sealing ring 21 is provided at the upper end of the lifting tube 16, positioned within the flow chamber 14. The sustained-release tablet 7 covers the second sealing ring 21. When the lifting tube 16 is in the lower position under the action of the second elastic member 18, the second sealing ring 21 abuts against the sealing step 20, thereby sealing the flow chamber 14. To achieve a better sealing effect, a second sealing ring may be provided on the lower end surface of the second sealing ring 21. When the lifting tube 16 is in the lower position, the second sealing ring 21 abuts against the sealing step 20, thereby achieving a better sealing effect.

[0080] In this embodiment, the liquid storage chamber 5 is further provided with a rotating chamber 22. The flow chamber 14 of the rotating member 13 is located within the rotating chamber 22. An external hole 23 is defined on the side of the rotating chamber 22. During liquid inflow, the cleaning liquid in the cleaning liquid chamber 3 flows into the liquid storage chamber 5 via the liquid inlet line 6, the lotion pump 12, the lift tube 16, the lift tube's inner hole 17, the flow chamber 14, the middle hole in the flow chamber 14, and the external hole 23 in the rotating chamber 22. When liquid is not inflowing, due to the middle hole in the flow chamber 14 and the outer hole 23 defined on the side of the rotating chamber 22, the cleaning liquid in the liquid storage chamber 5 flows into the flow chamber 14 through the outer hole 23 and the middle hole.

[0081] In this embodiment, an upper sealing ring 24 and a lower sealing ring 25 are provided between the outer side wall of the flow chamber 14 of the rotating member 13 and the rotating chamber 22, and the outer hole 23 is located between the upper sealing ring 24 and the lower sealing ring 25, thereby preventing the cleaning liquid from leaking between the outer side wall of the flow chamber 14 and the inner wall of the rotating chamber 22.

[0082] In this embodiment, an anti-overflow sealing ring 26 is provided between the lifting tube 16 and the insertion cavity 15 to prevent leakage of the cleaning liquid from between the lifting tube 16 and the insertion cavity 15 .

[0083] In this embodiment, the brush head 2 has a release channel extending upward from the release port; the rotating member 13 includes an outer sleeve 27 located in the rotating chamber 22, and an inner sleeve 28 sleeved in the outer sleeve 27. The motor 9 is connected to the outer sleeve 27. The inner sleeve 28 includes an upper sleeve 29 located in and connected to the outer sleeve 27, and a lower sleeve 30 inserted into the release channel of the brush head. The space in the upper sleeve 29 forms the flow chamber 14. The lower sleeve 30 is connected to the release channel so that the rotating member 13 and the brush head 2 can rotate synchronously; the middle hole includes a first middle hole 31 opened on the outer sleeve 27 and a second middle hole 32 opened on the upper sleeve 29.

[0084] In this embodiment, the inner wall of the release channel and / or the outer wall of the lower sleeve 30 are provided with threaded grooves, and the release channel and the lower sleeve 30 are engaged with each other through the threaded grooves. Of course, the connection between the release channel and the lower sleeve 30 can also be achieved by threaded connection, screw or rivet connection, adhesive bonding, etc.

[0085] In this embodiment, the inner wall of the outer sleeve 27 is provided with a positioning rib 33, and the outer wall of the upper sleeve 29 is provided with a positioning groove 34. The positioning rib 33 is inserted into the positioning groove 34, thereby achieving the connection between the outer sleeve 27 and the upper sleeve 29. Alternatively, the inner wall of the outer sleeve may be provided with a positioning groove, and the outer wall of the upper sleeve may be provided with a positioning rib, and the positioning rib is inserted into the positioning groove. Of course, the outer sleeve and the upper sleeve can also be connected by threaded connection, screw or rivet connection, adhesive bonding, etc.

[0086] A flow gap may be provided between the upper sleeve 29 and the outer sleeve 27. This advantageously allows the cleaning liquid in the liquid storage chamber 5 to flow from the first central hole 31 through the flow gap and then into the second central hole 32. In this case, the first central hole 31 does not need to be directly opposite the second central hole 32, which simplifies assembly. Of course, the upper sleeve 29 and the outer sleeve 27 may also be tightly fitted, in which case the first central hole 32 must be directly opposite the second central hole 32.

[0087] In this embodiment, a motor cavity 75 is provided at the lower end of the brush handle, and the motor 9 is located in the motor cavity 75 . At this time, the liquid storage cavity 5 can be connected to the motor cavity 75 to achieve fixation.

[0088] The brush handle 1 described in this embodiment includes an upper handle 35 and a lower handle 36. The upper and lower handles 35 and 36 are detachably connected, which reduces the height of the packaging box. The power supply 10 and circuit board 11 are located in the upper handle 35, and the motor 9 is located in the lower handle 36. The circuit board 11 is provided with an upper pin 37, and the lower handle 36 is provided with a lower pin 38. When the upper and lower handles 35 and 36 are connected, the upper pin 37 contacts the lower pin 38, which is then connected to the motor 9 via a wire 39. A slot 40 can be provided in the upper handle 35, into which the circuit board 11 is inserted, facilitating installation of the circuit board 11.

[0089] The design of upper pins 37 and lower pins 38 is used only to describe the electrical connection of the circuit board and is not strictly limited to a "pin-shaped" design. For example, upper pins 37 could be pins on the lower portion of circuit board 11 itself, with a conductive layer on top; lower pins 38 could be lower pins with a conductive layer on top; or upper pins 37 could be conductive sockets, with lower pins 38 inserted into the sockets. Upper pins 37 and lower pins 38 could be connected sideways or with end-to-end contact.

[0090] There are various ways to detachably connect the upper handle 35 and the lower handle 36. They can be a snap-fit ​​connection, a screw connection, or a tab on the upper handle and a slot on the lower handle, with the tab inserted into the slot. In this embodiment, a lower snap block 41 is provided on the outer sidewall of the lower handle 36, and an upper snap block 42 is provided on the inner sidewall of the upper handle 25. When the upper handle 35 is attached to the lower handle 36, the upper snap block 42 passes over the lower snap block 41 from top to bottom, preventing the upper handle 35 from being disengaged. To disassemble the upper handle 35, the upper and lower handles 35 and 36 can be disassembled by pulling the upper handle 35 upward. The upper snap block 42 passes over the lower snap block 41 from bottom to top. To ensure smooth passage of the upper snap block 42 over the lower snap block 41, the upper and lower end surfaces of the lower snap block 41 are preferably inclined. In addition, an elastic flap 43 can be provided on the lower handle 36, and the lower buckle block 41 is provided on the elastic flap 43.

[0104] As in the previous embodiment, the valve device can be a solenoid valve installed on the liquid inlet pipeline 6; the valve device can also be a manual valve installed on the liquid inlet pipeline 6, and the manual valve is connected to a driving mechanism for driving it to open and close. The valve device can also be a lotion pump 12 installed at the second end of the liquid inlet pipeline 6. When the brush head 2 is placed in the brush head cavity 4, the lotion pump 12 is pressed downward by the brush head 2, thereby opening the lotion pump 12. When the brush head 2 is removed, the lotion pump 12 automatically closes due to its own elastic force.

[0105] In this embodiment, the specific structure of liquid inlet and release of cleaning liquid is as follows: the brush head 2 is provided with a liquid inlet pipe 67 located below the liquid storage chamber. After the brush head 2 is placed in the brush head chamber 4, the lower end of the liquid inlet pipe 67 is connected to and contacts the lotion pump 12, and the upper end of the liquid inlet pipe 67 penetrates into the liquid storage chamber 5. The sustained-release tablet 7 is provided on the upper end of the liquid inlet pipe 67.

[0106] A liquid inlet hole 68 is provided on the side wall of the liquid inlet pipe 67. When the brush head 2 is not pressed down, the liquid inlet hole 68 is located below the liquid storage chamber 5. After the brush head 2 is pressed down a first distance, the liquid inlet hole 68 is located in the liquid storage chamber 5. The brush head 2 continues to be pressed down, pressing the lotion pump 12 through the liquid inlet pipe 67, thereby opening the lotion pump 12. The cleaning liquid in the cleaning liquid chamber 3 flows into the liquid storage chamber 5 via the liquid inlet pipeline 6, the lotion pump 12, the liquid inlet pipe 67, and the liquid inlet hole 68 on the liquid inlet pipe 67.

[0107] After the brush head 2 is no longer pressed, the toilet brush rises, and the liquid inlet hole 68 on the liquid inlet pipe 67 is once again located below the liquid storage chamber 5. When the cleaning liquid needs to be released, the air is blown into the liquid storage chamber 5 through the air blowing device. Under the action of the air pressure, the cleaning liquid in the liquid storage chamber 5 is discharged from the liquid inlet pipe 67 through the sustained-release tablet 7 and released to the outside of the brush head 2 through the release port 19. It is best to arrange the liquid inlet pipe 67 and the release port 19 in a facing position to ensure smooth release of the cleaning liquid. In this embodiment, it is best to configure the connecting column 66 to be hollow and pass through the connector 65. Then, an air inlet hole 69 is formed on the side wall of the connecting column 66. During air blowing, the gas enters the hollow portion through the air inlet hole 69 and ultimately enters the liquid storage chamber 5.

[0108] In this embodiment, the liquid inlet pipe 67 is provided with a pressing portion 70, and the lotion pump 12 is provided with a pressure-receiving portion 71. The pressing portion 70 contacts the pressure-receiving portion 71. After the toilet brush is pressed down to a first distance, it continues to press the pressing portion 70. The pressing portion 70 presses the pressure-receiving portion 71 downward, thereby pressing the lotion pump 12. The pressing portion 70 in this embodiment is provided on the outer surface of the liquid inlet pipe 67. The pressing portion 70 is provided with a shoulder 72 corresponding to the liquid storage chamber 5. After the brush head is pressed down to the liquid storage chamber 5 and contacts the shoulder 72, it continues to press down, driving the pressing portion 70 downward, thereby pushing the pressure-receiving portion 71 downward. The pressing portion 70 in this embodiment has a receiving cavity, in which a first elastic device 73 (typically a spring) is disposed. The elastic force of the first elastic device 73 is less than the elastic force of the lotion pump 12 itself. The lower end of the first elastic device 73 presses against the receiving cavity, while the upper end of the first elastic device 73 presses against the liquid storage cavity 5. Under the action of the first elastic device 73, the liquid storage cavity 5 has an upward tendency.

[0109] In this embodiment, a first sealing ring 74 is provided at the upper end of the liquid inlet pipe 67; the first sealing ring 74 is located in the liquid storage chamber 5. When the toilet brush is not pressed down, a seal is formed between the first sealing ring 74 and the bottom surface of the liquid storage chamber 5. The sustained-release tablet 7 is disposed on the first sealing ring 74. A second sealing ring may also be provided at the lower end surface of the first sealing ring 74. The first sealing ring 74 forms a seal between the first sealing ring and the bottom surface of the liquid storage chamber 5, thereby achieving a better sealing effect.
