Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] like Figures 1-6As shown, this utility model provides a toilet brush capable of dispensing foam cleaner, including a brush head 1 and a handle 2. The brush head 1 is fixedly connected to the handle 2, and a nozzle 3 is fixedly installed on the brush head 1. The handle 2 is hollow inside, and a partition 4 is provided inside the handle 2, dividing the internal space of the handle 2 into a sealed cavity 5 and an assembly cavity 6. An air pump 7, a battery 8, and an electronic control board 9 are fixedly installed in the sealed cavity 5. A bottle body 10 and a foamer 11 are fixedly installed in the assembly cavity 6. A bracket 12 is fixedly installed at the outlet of the bottle body 10, and a shrink bag 13 is fixedly connected to the bracket 12. The air pump 7 and the outlet of the bottle body 10 are both connected to the foamer 11 through pipes 14. The foamer 11 is connected to the nozzle 3 through an output pipe 15. The handle 2 is provided with a control button 16. A wireless charging coil 17 is fixedly installed on the electronic control board 9. The air pump 7 is a dual pump, and the air pump 7 is connected to the bottle body 10 through an air pipe 18. The bottle body 10 is fixedly connected to the liquid filling pipe 19 and the pressure relief pipe 20. The liquid filling pipe 19 is fixedly installed with a one-way valve 21, and the opening of the pressure relief pipe 20 is sealed with a cap 22. The shrink bag 13 is made of elastic rubber.

[0022] Through the above technical solution, a bracket 12 is fixedly installed at the outlet of the bottle body 10 of this utility model. A shrink bag 13 is fixedly connected to the bracket 12. The shrink bag 13 is used to store cleaning agent. The shrink bag 13 is tightened according to the amount of cleaning agent to ensure that there is always cleaning agent at the outlet of the bottle body 10. When in use, the cleaning liquid enters the foamer 11 through the pipe 14. At the same time, the air pump 7 pumps air into the pipe 14, so that the cleaning liquid foams in the foamer 11. Then, it is delivered to the nozzle 3 of the brush head 1 through the output pipe, so that the brush head 1 has cleaning agent foam, thereby improving the cleaning effect of the toilet brush.

[0023] Example 2:

[0024] like Figures 1-6 As shown, this embodiment consists of two parts: a brush head 1 and a brush handle 2, which are fixedly connected. The brush head 1 is equipped with a specially designed nozzle 3 structure for evenly spraying foam cleaner. The brush handle 2 has a hollow internal structure, with an internal partition 4 dividing the space into two functional areas: a sealed cavity 5 and an assembly cavity 6.

[0025] Inside the sealed cavity 5 of the brush handle 2, core components such as the air pump 7, battery 8, and control circuit board are installed. The air pump 7 provides compressed air, the battery 8 powers the entire system, and the control board 9 coordinates the operation of each component. These components are waterproofed and sealed to ensure normal operation in humid environments. The design of the sealed cavity 5 effectively protects the internal electronic components from moisture corrosion.

[0026] The assembly cavity 6 houses a cleaning agent storage system and a foam generator. The cleaning agent is stored in a dedicated bottle 10, which has a special bracket 12 at its outlet. The bracket 12 is connected to a shrink bag 13, which automatically shrinks as the cleaning agent usage decreases, ensuring a constant supply of cleaning agent at the bottle 10 outlet. This design solves the problem of unstable pumping when the liquid level is low with traditional containers. The bracket 12 also prevents the shrink bag 13 from clogging the bottle 10 outlet when the cleaning agent level is low.

[0027] The foamer 11, as a key component, is fixed inside the assembly cavity 6 and connected to the air pump 7 and the outlet of the bottle 10 via a system of pipes 14. When the system is working, the cleaning fluid and compressed air simultaneously enter the foamer 11 and mix. The foamer 11 employs a special internal structural design to ensure thorough mixing of liquid and air to form fine foam. The generated foam is delivered to the nozzle 3 of the brush head 1 through the output pipe 15.

[0028] The brush handle 2 has an external operation control button 16, which allows the user to control the foam output with simple pressing. After receiving the button signal, the electronic control board 9 coordinates the operation of the air pump 7 and the delivery of cleaning agent. When the entire system is working, compressed air pushes the cleaning agent into the foamer 11, where it forms uniform foam before being sprayed out from the nozzle 3. The special design of the nozzle 3 ensures that the foam is evenly distributed on the surface of the brush head 1.

[0029] This embodiment employs a shrink-fit bag 13 to store the cleaning agent, working in conjunction with the air pump 7 and the foamer 11. The shrink-fit bag 13 automatically shrinks as the cleaning agent decreases, maintaining constant pressure on the cleaning agent at the outlet of the bottle 10 to ensure stable delivery. The compressed air supplied by the air pump 7 is thoroughly mixed with the cleaning agent within the foamer 11, forming a fine and uniform cleaning foam. This design significantly improves the utilization rate of the cleaning agent and the cleaning effect.

[0030] In use, the user simply presses the control button 16 on the brush handle 2, and the system automatically generates foam and delivers it to the brush head 1. The foamy cleaning agent adheres better to the toilet surface, improving cleaning efficiency. The entire operation does not require direct contact with the cleaning agent, making it both hygienic and convenient. This system is particularly suitable for use in family bathrooms, solving the problems of cumbersome operation and poor results associated with traditional toilet brushes that use cleaning agents.

[0031] This embodiment optimizes the internal structural layout, effectively isolating electronic components from the liquid storage area, thus improving product safety and reliability. All connecting pipes 14 are sealed to prevent liquid leakage. The battery 8 power supply system ensures wireless operation, increasing ease of use. The overall design fully considers the usage requirements in the humid environment of a bathroom.

[0032] Example 3:

[0033] like Figures 1-6 As shown, this embodiment uses wireless charging technology to charge the battery 8 inside the sealed cavity 5, which effectively improves the sealing performance and ease of use of the product.

[0034] Within the sealed cavity 5 inside the brush handle 2, a wireless charging coil 17 is fixedly mounted on the electronic control board 9. This wireless charging coil 17 operates on the principle of electromagnetic induction. When an external wireless charger emits an alternating electromagnetic field, an induced current is generated inside the coil. After being rectified and regulated by the electronic control board 9, this current charges the battery 8 inside the sealed cavity 5. This charging method completely avoids the problem of needing a charging interface in traditional wired charging, thus ensuring the complete sealing of the sealed cavity 5.

[0035] In practical use, users simply place the toilet brush on the accompanying wireless charging base to begin charging. The charging base's built-in transmitting coil generates an alternating magnetic field, transferring energy to the receiving coil inside the toilet brush through electromagnetic induction. The entire charging process requires no physical contact, completely eliminating the risk of liquid seepage that can occur with traditional charging interfaces, and significantly improving the product's waterproof performance and safety.

[0036] This wireless charging system supports the standard Qi wireless charging protocol and is compatible with most wireless charging devices on the market. During charging, indicator lights on the control board 9 will display the charging status, allowing users to easily monitor the charging progress. Once the battery 8 is fully charged, the system will automatically stop charging to avoid energy waste and damage to the battery 8.

[0037] Thanks to wireless charging technology, the sealed cavity 5 can be completely closed, effectively preventing moisture, cleaning agents, and other liquids that may be generated during cleaning from seeping into the internal electronic components. This design significantly improves the product's durability and reliability, making it particularly suitable for use in humid environments like bathrooms. At the same time, the convenience of wireless charging greatly enhances the user experience; users no longer need to search for a charging cable every time they charge, simply placing the device on the wall to complete the charging process.

[0038] This embodiment, through an innovative wireless charging solution, not only solves the sealing problem of traditional wired charging but also provides users with a more convenient and safer charging experience. The application of wireless charging technology makes the product more aesthetically pleasing and streamlined, with no exposed charging ports, enhancing the product's perceived quality and user comfort. At the same time, this design facilitates daily cleaning and maintenance, preventing dirt accumulation on the charging ports from affecting usability.

[0039] Example 4:

[0040] like Figures 1-6As shown, the air pump 7 in this embodiment is a dual-pump system, ensuring stable output and efficient foaming of the cleaning solution. The brush head 1 is fixedly connected to the brush handle 2. The brush head 1 is equipped with a nozzle 3. The brush handle 2 has a hollow internal structure, divided into a sealed cavity 5 and an assembly cavity 6 by a partition 4. The sealed cavity 5 houses the dual-pump air pump 7, the battery 8, and the electronic control board 9. The assembly cavity 6 houses the bottle body 10 and the foamer 11. A bracket 12 is provided at the outlet of the bottle body 10, and the bracket 12 is connected to a shrinkable bag 13 for storing the cleaning agent.

[0041] One pump of the dual-pump air pump 7 is connected to the bottle 10 via air pipe 18, and the other pump is connected to the foamer 11 via pipe 14. When the control button 16 is pressed, the system starts its workflow. First, the air pump 7 connected to the bottle 10 begins to fill the bottle 10 with air, and the air pressure inside the bottle 10 gradually increases. The increased air pressure acts on the outer surface of the shrink bag 13, generating a uniform squeezing force on the shrink bag 13. Due to the good elastic deformation characteristics of the shrink bag 13, it gradually shrinks under the action of air pressure, smoothly squeezing out the cleaning liquid stored inside.

[0042] The squeezed-out cleaning liquid flows through pipe 14 to the foamer 11. Simultaneously, the other pump in the dual-pump air pump 7 starts operating, delivering compressed air to the foamer 11 through an independent pipe 14. Inside the foamer 11, the cleaning liquid encounters the high-speed airflow and mixes vigorously. The foamer 11 has a special internal structure that allows the liquid and air to come into full contact, forming numerous tiny bubbles. This mixing process transforms the liquid cleaning agent into a rich, foamy cleaning agent.

[0043] The generated foam cleaner is then delivered through the output pipe 15 to the nozzle 3 of the brush head 1. The nozzle 3 is specially designed to distribute the foam evenly on the surface of the brush head 1. Due to the large surface area and good adhesion of the foam, it can more effectively cover and break down dirt on the toilet surface. Throughout the process, the shrinkage of the shrink bag 13 automatically adjusts as the cleaning liquid decreases, ensuring that there is always a sufficient supply of cleaning liquid at the outlet of the bottle 10.

[0044] When not in use, the system automatically cuts off the power to the air pump 7. At this time, the air pressure inside the bottle 10 gradually returns to normal, and the shrink bag 13 maintains an appropriate shape according to the amount of remaining cleaning fluid. This design avoids the pumping instability problem that occurs with traditional containers when the liquid level decreases, ensuring a consistent foam output effect every time it is used. Through this dual-pump collaborative operation, efficient utilization and stable output of the cleaning fluid are achieved, greatly improving the toilet cleaning effect and ease of use.

[0045] Example 5:

[0046] like Figures 1-6As shown, in this embodiment, the bottle body 10 is fixedly connected to a liquid filling pipe 19 and a pressure relief pipe 20. A one-way valve 21 is fixedly installed on the liquid filling pipe 19, and a cap 22 is sealed at the opening of the pressure relief pipe 20. When adding detergent to the shrink bag 13 of the bottle body 10 through the liquid filling pipe 19, the one-way valve 21 effectively prevents the detergent from flowing back from the liquid filling pipe 19 to the outside. The pressure relief pipe 20 releases air inside the bottle body 10 during the detergent addition process, allowing the shrink bag 13 to expand smoothly. After the detergent is added, the cap 22 is sealed to block the pressure relief pipe 20, ensuring a sealed space inside the bottle body 10. During use, the air pump 7 pressurizes the bottle body 10, driving a stable output of detergent.

[0047] The toilet brush works as follows: When the control button 16 is pressed, the electronic control board 9 controls the air pump 7 to work, pumping air into the foamer 11 through the pipe 14. Simultaneously, the pressure inside the bottle 10 pushes the detergent in the shrink bag 13 through the pipe 14 into the foamer 11. Inside the foamer 11, the detergent and air mix thoroughly to form foam, which is then delivered to the nozzle 3 of the brush head 1 through the output pipe 15 and sprayed out. Because the shrink bag 13 shrinks as the detergent decreases, it always maintains close contact with the outlet of the bottle 10, ensuring that the detergent is fully utilized and no residue remains.

[0048] During use, when the cleaning agent needs to be replenished, simply open the cap 22 of the pressure relief pipe 20 and inject new cleaning agent through the filling pipe 19. At this time, the air inside the bottle 10 can be discharged through the pressure relief pipe 20, allowing the shrink bag 13 to expand smoothly to accommodate the new cleaning agent. After adding, reseal the pressure relief pipe 20 to resume normal use. This design ensures both ease of use and the system's sealing performance.

[0049] Example 6:

[0050] like Figures 1-6 As shown, the brush handle 2 in this embodiment has a partition 4 inside, dividing the space into a sealed cavity 5 and an assembly cavity 6. The sealed cavity 5 houses an air pump 7, a battery 8, and an electronic control board 9, while the assembly cavity 6 houses a bottle 10 and a foamer 11. A bracket 12 connects to a shrink bag 13 at the outlet of the bottle 10. This shrink bag 13 is made of elastic rubber. When detergent flows from the bottle 10 into the shrink bag 13, the elastic rubber shrink bag 13 automatically adjusts its shape according to changes in the detergent dosage. When the detergent dosage is high, the shrink bag 13 fully expands to contain the liquid; as the amount of detergent used decreases, the shrinkage properties of the elastic rubber cause the bag to gradually tighten, always maintaining a seal at the outlet of the bottle 10.

[0051] The shrink bag 13, made of elastic rubber, has excellent resilience and chemical resistance, maintaining its elasticity over a long period. When the detergent is pumped out, the shrink bag 13 continuously contracts inwards due to its elasticity, pushing any remaining detergent towards the outlet of the bottle 10. This design ensures a stable liquid delivery pressure regardless of the amount of detergent remaining, preventing pumping instability caused by insufficient liquid volume.
