[0001] This utility model relates to a manual coating tool in the field of surface care, specifically a press-type volume control device for coating surface care liquids. Background Technology

[0002] A coating device is a container used to store surface care liquid. After applying a layer of care liquid or care gel to the surface of the clothing or fabric, it is then smoothed with another cloth pad. However, existing coating devices of this type generally use a squeezing method to dispense the liquid, which can easily lead to problems such as excessive liquid output or dripping after squeezing, resulting in serious waste. Moreover, uneven application is also prone to occur during coating. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this invention is to provide a press-type volume control device for coating surface care liquids to solve the problems mentioned in the background art, such as the use of extrusion to discharge material, which easily leads to excessive liquid output or dripping after extrusion, resulting in serious waste.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a press-type volume control device for coating surface care liquid, comprising a liquid storage container, wherein a partition is provided inside the liquid storage container to separate the liquid storage container into upper and lower layers, and a liquid channel is provided on the partition to connect the upper and lower layers of the liquid storage container. An elastic valve assembly is provided within the liquid channel, which opens when pressed and closes when not pressed. The bottom of the lower layer of the liquid storage container is open, and a flexible diaphragm valve and a coating cloth pad are provided at the opening of the lower layer of the liquid storage container. A pressing head is provided at the center of the top surface of the flexible diaphragm valve. The flexible diaphragm valve is also provided with one or more liquid guiding holes. The coated pad is located below the flexible diaphragm valve. The elastic valve body assembly includes a valve seat body, a valve core, and a spring. The valve seat body is provided with a first liquid guiding hole and a liquid guiding channel. The upper part of the valve core passes through the liquid guiding channel and is built into the valve seat body. The lower part of the valve core extends out of the valve seat body and is placed in the lower layer of the liquid storage container. The upper part of the valve core is sleeved with a spring whose upper end abuts against the valve seat body and whose lower end abuts against the valve core. A second liquid guiding hole is also provided below the valve core. When the valve core moves upward, the second liquid guiding hole can communicate with the first liquid guiding hole.

[0005] Preferably, for ease of disassembly, the valve seat body includes an upper valve seat and a lower valve seat, which are interlocked. The upper valve seat has a limiting step on its side that is engaged with the lower port of the liquid channel. A sealing ring is provided between the upper and lower valve seats. The upper and lower valve seats cooperate to form a liquid guiding chamber. The liquid guiding channel is located at the center of the lower valve seat. The upper valve seat has two or more liquid guiding holes arranged in a ring on its upper side. The liquid guiding holes communicate with the liquid guiding chamber. The valve core includes a valve core seat and a valve core rod. The bottom of the valve core seat has two or more liquid guiding holes arranged in a ring on its lower side. The top side of the valve core seat has a limiting step with a diameter larger than the liquid guiding channel. The valve core rod is located at the top center of the valve core seat. The spring is sleeved on the outside of the valve core rod. The top of the valve core rod is inserted into the top of the upper valve seat.

An elastic valve assembly is provided within the liquid channel 3, opening when pressed and closing when not pressed. The bottom of the lower layer of the liquid storage container 1 is open, and a flexible diaphragm valve 4 and a coating pad 5 are provided at the opening. A pressing head 6 is provided at the center of the top surface of the flexible diaphragm valve 4. The flexible diaphragm valve 4 also has one or more liquid guiding holes 7 to ensure more uniform and comprehensive liquid dispensing. 7 are arranged in a ring around the pressing head 6 on the flexible diaphragm valve 4, and the liquid guiding hole 7 is elongated. The coated pad 5 is located below the flexible diaphragm valve 4. The elastic valve body assembly includes a valve seat body 8, a valve core 9, and a spring 10. The valve seat body 8 is provided with a liquid guiding hole 12 and a liquid guiding channel 13. The upper part of the valve core 9 passes through the liquid guiding channel 13 and is built into the valve seat body 8. The lower part of the valve core 9 extends out of the valve seat body 8 and is placed in the lower layer of the liquid storage container 1. The upper part of the valve core 9 is sleeved with a spring 10, the upper end of which abuts against the valve seat body 8 and the lower end of which abuts against the valve core 9. A second liquid guiding hole 11 is also provided below the valve core 9. When the valve core 9 moves upward, the second liquid guiding hole 11 can communicate with the first liquid guiding hole 12.

[0023] Preferably, for ease of disassembly, the valve seat body 8 includes an upper valve seat 801 and a lower valve seat 802, which are interlocked. The upper valve seat 801 has a limiting step 803 on its side that engages with the lower port of the liquid channel 3. A sealing ring 804 is provided between the upper valve seat 801 and the lower valve seat 802. The upper valve seat 801 and the lower valve seat 802 cooperate to form a liquid guiding chamber 805. The liquid guiding channel 13 is located at the center of the lower valve seat 802. The upper valve seat 801 has two or more liquid guiding holes 12 arranged in a ring on its upper surface. The liquid guiding holes 12 and the liquid guiding chamber 802 are connected... 5. The valve core 9 includes a valve core seat 901 and a valve core rod 902. The bottom of the valve core seat 901 is provided with two or more liquid guiding holes 11 in an annular shape. The top side of the valve core seat 901 is provided with a limiting step 14 with a diameter larger than that of the liquid guiding channel 13. The valve core rod 902 is placed at the top center of the valve core seat 901. The spring 10 is sleeved on the outside of the valve core rod 902. The top of the valve core rod 902 is inserted into the top of the upper valve seat 801. The upper end of the pressing head 6 is inserted into the bottom center of the lower valve seat 802. With the above structural configuration, the entire elastic valve body assembly can be quickly disassembled.

[0024] As a preferred option, to improve the dustproof effect, the liquid storage container 1 is provided with a fastening groove 15 on both the front and rear sides, and a dustproof cover 16 is fastened between the two fastening grooves 15. The inner wall of the dustproof cover 16 is provided with a retaining strip 17 that cooperates with the fastening groove 15. This structure can achieve the dustproof effect by adding a dustproof cover 16.

[0025] Preferably, for ease of operation, the upper part of the liquid storage container 1 is provided with an inner groove 19 that communicates with the upper layer of the liquid storage container 1. A sealing cap 20 is inserted into the inner groove 19. A racetrack-shaped handle 21 is provided above the sealing cap 20. For easy brand identification, a flat area 22 for pasting brand information is provided at the upper end of the racetrack-shaped handle 21.

[0026] The liquid storage container 1 in this structure is used to hold the nursing solution, and a sealing cap 20 is provided on the top of the liquid storage container 1 to further prevent dust and seal the liquid, thus preventing leakage. Meanwhile, an elastic valve assembly is added to the liquid channel 3. In use, the user holds the racetrack-shaped handle 21, places the coating pad 5 on the area to be coated, and presses down firmly. The coating pad 5 moves upward, pushing the flexible diaphragm valve 4 upward. At this time, the pressing head 6 moves upward, pushing the valve core rod 902 upward (simultaneously compressing the spring 10). The second liquid guide hole 11 on the valve core rod 902 then connects with the liquid guide channel 13, allowing the liquid in the liquid storage container 1 to flow into the liquid channel 3, and then into the liquid guide chamber 805 through the first liquid guide hole 12. Finally, it flows from the liquid guide channel 13 into the second liquid guide hole 11, ultimately flowing evenly onto the coating pad 5. The coating pad 5 penetrates the surface of the area to be coated. When the external force disappears, the spring 10... When the valve core rod 902 is lowered and reset, it ensures that the liquid guide hole 11 on the valve core rod 902 is separated from the liquid guide channel 13. At the same time, it pushes the flexible diaphragm valve 4 and the coating pad 5 below to move and reset downwards. Moreover, under the action of the side wall of the valve core rod 902, the liquid guide channel 13 is sealed, resulting in the entire flow channel being closed and leak-free. Therefore, this structure can achieve liquid discharge only when pressed, and no liquid discharge when not operated. Ultimately, a press-to-control liquid mechanism is achieved, where the pressing head 6 drives the spring to push the flexible diaphragm valve 4 to open the liquid outlet, realizing a "one press, one discharge" liquid control mechanism. It automatically closes when released, without dripping, and the liquid discharge is uniform, preventing waste. No additional tools are required, saving operation steps. In addition, since the liquid guide hole 11 is evenly distributed, uniform coating is achieved. The coating pad 5 is movably fastened to the bottom of the liquid storage container 1, and the coating pad 5 can be removed later to replace the scouring pad or cotton pad.
