Description

Technical Field

[0001] This utility model relates to the field of water tank cap technology, specifically to a water tank cap for a spray mop. Background Technology

[0002] In cleaning tools such as water-spraying mops, the water tank, as the water storage component, directly affects the user experience and transportation safety. The water tank cap, as a key sealing structure, not only needs to effectively seal the stored water but also needs to work with the water outlet assembly to achieve controlled drainage, and balance the air pressure inside and outside the water tank through air intake during the drainage process.

[0003] Currently, most water tank caps on the market use a self-tightening sealing ring structure to achieve air intake and closure functions. Its working principle is similar to the design of the nipple of a baby bottle. It relies on the elastic deformation of the silicone itself to form a seal. When draining, the silicone opening is naturally opened by the air pressure difference to allow air to enter. After draining, it returns to its original position and closes by the elasticity of the silicone itself.

[0004] However, this structure, which relies solely on the elasticity of silicone, has certain drawbacks: due to the limited elastic modulus of silicone, its sealing performance is easily affected by the external environment. During product transportation, frequent bumps, vibrations, and pressure shocks may cause the silicone seal to open unexpectedly; even when stationary, prolonged stress relaxation or temperature changes may cause micro-cracks to appear at the silicone seal, ultimately leading to leakage of liquid inside the tank. This problem not only affects product reliability but may also lead to damage during transportation, increase after-sales costs, and provide a poor user experience. Therefore, improvements are needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water tank cap for a spray mop, which solves the problems mentioned in the background art.

[0006] The solution of this utility model to the above-mentioned technical problems is as follows:

[0007] A water tank cap for a spray mop, comprising a water tank cap body,

[0008] The water tank cap body integrates a water outlet component and an air inlet component; wherein, the water outlet component is used to discharge the water stored in the water tank of the spray mop, and the air inlet component is used to simultaneously introduce gas into the water tank when the water outlet component is draining, so as to balance the air pressure inside and outside the water tank; the water tank cap body is provided with positioning holes.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the water outlet assembly includes a water outlet unit and a closing unit, wherein the water outlet unit is used to discharge the water stored in the water tank of the spray mop, and the closing unit is used to seal and close the water outlet unit before and after the drainage operation.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] By separating the water outlet component into independent water outlet and closure units, the drainage and sealing functions are clearly separated, ensuring both smooth drainage and reliable sealing in non-drainage states. The clear division of labor in the structure facilitates assembly and subsequent maintenance.

[0013] Furthermore, the water outlet unit includes a water outlet pipe, and a liquid outlet tank is provided inside the water outlet pipe.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The outlet pipe provides a directional delivery channel for water flow; the design of the liquid outlet tank ensures uniform and stable water output, while also facilitating cooperation with the closure unit to form a sealing structure and improve sealing accuracy.

[0016] Furthermore, the closing unit includes a first silicone sealing block, which is installed inside the water outlet unit by a first reset spring, and the first silicone sealing block limits the liquid outlet tank.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The silicone material has good elasticity and sealing properties, and can fit tightly with the liquid outlet. The first reset spring provides continuous pre-tightening force, which can ensure that the first silicone sealing block is always tightly pressed against the liquid outlet, effectively solving the problem of unreliable sealing caused by relying solely on the elasticity of silicone itself, avoiding liquid leakage during transportation or when standing still. At the same time, during drainage, the water pressure can overcome the spring force to achieve smooth drainage, and the seal is reset after drainage.

[0019] Furthermore, the air intake assembly includes an air intake unit and a sealing unit. The air intake unit is used to introduce gas into the water tank during drainage operations, and the sealing unit is used to seal and close the air intake unit after balancing the air pressure inside and outside the water tank.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] By combining the air intake unit and the sealing unit, gas can be introduced in time during drainage to balance the air pressure inside and outside the water tank, ensuring smooth drainage without blockage. After the air pressure is balanced, the air intake channel can be sealed quickly to prevent liquid in the water tank from leaking through the air intake unit, thus achieving a dynamic balance between the air intake function and the sealing function.

[0022] Furthermore, the air intake unit includes an air intake pipe, a guide groove is provided inside the air intake pipe, and an air intake port is provided on the top surface of the air intake pipe.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The air inlet provides an independent channel for gas flow, avoiding interference with the water flow channel; the guide channel can guide the directional flow of gas; the air inlet is located on the top surface to facilitate the direct introduction of outside air, while reducing the risk of liquid backflow.

[0025] Furthermore, the sealing unit includes a second silicone sealing block, which is installed inside the air intake pipe by a second return spring, and the second silicone sealing block limits the air intake.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] The second silicone sealing block is adapted to the air inlet to form a tight seal; the second return spring provides continuous preload force to ensure that the sealing block reliably closes the air inlet in the non-air intake state to prevent liquid leakage; when a negative pressure is formed in the water tank, the external air pressure can overcome the spring force to push the sealing block open to allow air intake. After the air pressure is balanced, the spring returns to its original position and seals, and the spring preload force can effectively resist the impact of transportation bumps and improve the reliability of the seal.

[0028] This utility model provides a water tank cap for a spray mop. It has the following beneficial effects:

[0029] By setting a first return spring and a second return spring in the closing unit of the water outlet assembly and the sealing unit of the air inlet assembly respectively, a continuous and stable pre-tightening force is provided for the first silicone sealing block and the second silicone sealing block. This solves the problem of unreliable sealing caused by relying solely on the elasticity of silicone in the prior art, and effectively avoids liquid leakage during transportation due to bumps, pressure impacts or static placement.

[0030] The water outlet component and the air inlet component work independently yet in coordination. During drainage, the air inlet component synchronously introduces gas to balance the air pressure, ensuring smooth drainage without jamming. When not in operation, both components can reliably seal, achieving a dynamic balance of "drainage-air inlet-sealing" and improving the user experience. Attached Figure Description

[0039] 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.

[0040] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0041] Example

[0042] A water tank cap for a spray mop, comprising a water tank cap body 1,

[0043] The water tank cap body 1 integrates a water outlet component 2 and an air inlet component 3; wherein, the water outlet component 2 is used to discharge the water stored in the water tank of the spray mop, and the air inlet component 3 is used to simultaneously introduce gas into the water tank when the water outlet component 2 is draining, so as to balance the air pressure inside and outside the water tank; the water tank cap body 1 is provided with a positioning hole 101.

[0044] Furthermore, a positioning hole 101 is provided on the water tank cap body 1. The design of this positioning hole 101 is entirely based on the later assembly process and has no relation to the product's own functions (such as water dispensing, air intake, sealing, etc.). Since intermediate parts such as the water dispensing component 2 and the air intake component 3 inside the water tank cap have specific directional requirements during installation, deviations in the component orientation during assembly will not only affect the component installation accuracy but also prolong assembly time. To solve this problem, this positioning hole 101 is specifically added to the body, and its structure is a positioning recess. During later batch assembly operations, operators can align the parts' installation direction through this positioning recess, eliminating the need for repeated adjustments to the part's position. This effectively avoids rework due to misjudgment of orientation, significantly improving overall assembly efficiency and indirectly ensuring the stable operation of each component subsequently.

[0045] The water outlet assembly 2 includes a water outlet unit and a closing unit. The water outlet unit is used to discharge the water stored in the water tank of the spray mop, and the closing unit is used to seal the water outlet unit before and after the drainage operation. By splitting the water outlet assembly 2 into independent water outlet units and closing units, the drainage function and the sealing function are clearly separated, which ensures smooth drainage and reliable sealing in the non-drainage state. The structure has a clear division of labor, which is convenient for assembly and subsequent maintenance.

[0046] The water outlet unit includes a water outlet pipe 201, and a liquid outlet groove 204 is provided inside the water outlet pipe 201. The water outlet pipe 201 provides a directional delivery channel for water flow. The design of the liquid outlet groove 204 makes the water outlet uniform and stable, and at the same time facilitates the cooperation with the closing unit to form a sealing structure, thereby improving the sealing accuracy.

[0047] The closing unit includes a first silicone sealing block 202, which is installed in the water outlet unit via a first return spring 203. The first silicone sealing block 202 limits the liquid outlet groove 204. The silicone material has good elasticity and sealing properties, and can fit tightly with the liquid outlet groove 204. The first return spring 203 provides a continuous pre-tightening force, which can ensure that the first silicone sealing block 202 always presses tightly against the liquid outlet groove 204, effectively solving the problem of unreliable sealing caused by relying solely on the elasticity of silicone itself, avoiding liquid leakage during transportation or when standing still. At the same time, during drainage, the water pressure can overcome the spring force to achieve smooth drainage, and the seal is reset after drainage.

[0048] The air intake assembly 3 includes an air intake unit and a sealing unit. The air intake unit is used to introduce gas into the water tank during drainage operations. The sealing unit is used to seal and close the air intake unit after balancing the air pressure inside and outside the water tank. Through the cooperation of the air intake unit and the sealing unit, gas can be introduced in time during drainage to balance the air pressure inside and outside the water tank, ensuring smooth drainage without jamming. After the air pressure is balanced, the air intake channel can be sealed quickly to prevent liquid in the water tank from leaking through the air intake unit, thus achieving a dynamic balance between the air intake function and the sealing function.

[0049] The air intake unit includes an air intake pipe 301, a guide groove 304 is provided inside the air intake pipe 301, and an air inlet 302 is provided on the top surface of the air intake pipe 301. The air intake pipe 301 provides an independent channel for gas flow to avoid interference with the water flow channel; the guide groove 304 can guide the gas to flow in a specific direction; the air inlet 302 is located on the top surface to facilitate the direct introduction of outside air and at the same time reduce the risk of liquid backflow.

[0050] The sealing unit includes a second silicone sealing block 303, which is installed inside the air inlet pipe 301 via a second return spring 305. The second silicone sealing block 303 limits the air inlet 302 and is adapted to the air inlet 302 to form a tight seal. The second return spring 305 provides a continuous preload force to ensure that the sealing block reliably closes the air inlet 302 in the non-air intake state, preventing liquid leakage. When a negative pressure is formed in the water tank, the external air pressure can overcome the spring force to push open the sealing block to allow air intake. After the air pressure is balanced, the spring returns to its original position and seals. The spring preload force can effectively resist the impact of transportation bumps and improve the reliability of the seal.

[0051] Furthermore, the selection of the return spring needs to be adapted to the preload required for sealing and closure to avoid affecting water output and air intake.

[0052] Working principle:

[0053] Initial state:

[0054] In the water outlet assembly 2, the first reset spring 203 is in a pre-compressed state, pushing the first silicone sealing block 202 to tightly fit the liquid outlet groove 204, forming a seal on the water outlet pipe 201 and preventing the liquid in the water tank from flowing out.

[0055] In the air intake assembly 3, the second return spring 305 is in a pre-compressed state, pushing the second silicone sealing block 303 to tightly close the air intake port 302, preventing liquid in the water tank from leaking through the air intake pipe 301.

[0056] During drainage operation:

[0057] When water pressure is generated in the water tank (such as through the pressing or pressurizing mechanism of the mop and the direct connection of the water pump to the drainage position), the water pressure overcomes the pre-tightening force of the first reset spring 203, pushes the first silicone sealing block 202 to separate from the liquid outlet 204, the water outlet pipe 201 is opened, and the water stored in the water tank is discharged outward through the liquid outlet 204.

[0058] As the liquid is discharged, a negative pressure is formed inside the water tank. The external air pressure overcomes the preload of the second return spring 305, pushing the second silicone sealing block 303 to separate from the air inlet 302. Outside air enters the air inlet pipe 301 through the air inlet 302 and is guided into the water tank through the guide groove 304, simultaneously balancing the air pressure inside and outside the water tank to ensure smooth drainage.

[0059] After drainage is completed:

[0060] When the water pressure in the water tank disappears, the first reset spring 203 resets, pushes the first silicone sealing block 202 to re-fit tightly against the liquid outlet 204, closes the water outlet pipe 201, and restores the sealing state of the water outlet assembly 2.

[0061] After the air pressure inside and outside the water tank is balanced, the second reset spring 305 resets, pushes the second silicone sealing block 303 to close the air inlet 302 again, closes the air inlet pipe 301, restores the air intake assembly 3 to its sealed state, and prevents liquid leakage.

[0062] The entire process ensures that the silicone sealing block maintains a reliable seal when not in operation by using the continuous pre-tightening force provided by the spring. At the same time, the working state is automatically switched by the air pressure difference, which balances sealing performance and smooth operation.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
