DETAILED DESCRIPTION

[0027] The utility model relates to a kind of water supply tank device, the water supply tank device is suitable for being installed to a surface cleaning equipment and use, the water supply tank device is used to provide cleaning fluid for the roller brush on surface cleaning equipment or to ground, to improve cleaning efficiency and cleaning effect.

[0028] As Figures 1-3 Indicated, water supply tank device 100 includes: shell 10 and the water outlet valve 20, water filling cover 30 and release operation button 40 set on shell 10.

[0029] As Figures 2-4 Indicated, shell 10 includes water tank part 1 with liquid storage cavity 11 defined inside, and liquid storage cavity 11 is used to store cleaning fluid.Water tank part 1 has top wall 12 and bottom wall 13 opposite up and down, and bottom wall 13 is provided with water outlet 131 and water filling port 132 in communication with liquid storage cavity 11, water outlet 131 supplies cleaning fluid in liquid storage cavity 11 to be transported to the liquid injection port of water supply tank device 100 outward, to be able to spray cleaning fluid to roller brush or ground.Water filling port 132 supplies user to supplement cleaning fluid in liquid storage cavity 11.Water outlet valve 20 is movably arranged at water outlet 131 to open and close water outlet 131 operation, to control the output of cleaning fluid in liquid storage cavity 11.

[0030] Water filling cover 30 is rotatably combined on bottom wall 13 and is configured as being able to open and close water filling port 132, and when closing water filling port 132, effective sealing is carried out, to avoid cleaning fluid from water filling port 132 leakage.

[0031] As Figures 4-7 Indicated, release operation button 40 is adjacent to water filling port 132 and has a lock tongue part 2, and release operation button 40 is configured to be movably combined on bottom wall 13 between first position and second position.When release operation button 40 is in first position, lock tongue part 2 can be engaged with water filling cover 30, so that water filling cover 30 remains in the state of closing water filling port 132;When release operation button 40 is in second position, lock tongue part 2 is away from water filling cover 30, and the engagement between lock tongue part 2 and water filling cover 30 is released, and water filling cover 30 opens water filling port 132.

[0032] In the embodiment of the present application, the release button 40 is arranged in front of and behind the water inlet 132, and the water inlet 132 is located in front of the release button 40. The front end of the water cover 30 is hinged to the bottom wall 13, and the rear end of the water cover 30 is provided with a locking portion 3. The water cover 30 can rotate about the end hinged to the bottom wall 13. The locking portion 3 is provided with a locking hole 31 capable of cooperating with the locking tongue 2. When the release button 40 is in the first position, the locking tongue 2 is inserted into the locking hole 31 of the locking portion 3. The insertion between the locking tongue 2 and the locking portion 3 causes the water cover 30 to be kept in a state of closing the water inlet 132, so that even if the water tank device 100 is tilted, the water cover 30 will not be opened from the water inlet 132. When the release button 40 is moved to the second position, the locking tongue 2 exits the locking hole 31, and the locking tongue 2 and the locking portion 3 are separated. The water cover 30 can be rotated to open the water inlet 132. The release button 40 can be slidably combined on the bottom wall 13 between the first position and the second position. A spring (not shown in the figure) is arranged between the release button 40 and the bottom wall 13. When the release button 40 is in the second position, the spring is compressed between the release button 40 and the bottom wall 13. When the user does not apply a pushing force to the release button 40, the spring releases the elastic force to reset the release button 40 from the second position to the first position.

[0033] As shown in Figure 2 , 3 , the inner side of the water cover 30 is provided with an annular sealing ring 6. When the water cover 30 closes the water inlet 132, the annular sealing ring is in interference fit with the water inlet 132 to avoid water leakage of the water inlet 132.

[0034] In other embodiments, the end of the water cover 30 hinged to the bottom wall 13 is further provided with a torsional spring. When the release button 40 is in the second position, the torsional spring automatically opens the water cover 30 by pre-tightening force.

[0035] The bottom wall 13 is provided with a recess 133. The release button 40 is located in the recess 133 and is substantially in the same plane as the water cover 30 in the state of closing the water inlet 132.

[0036] Continuing to refer to Figures 1-3 , the top wall 12 is provided with an air inlet 121 communicating with the atmosphere. The air inlet 121 is used for air to enter the liquid storage cavity 11 to ensure that the pressure inside the water tank portion 1 is normal. The top wall 12 is formed with a recessed handle 122. The air inlet 121 is located at the recessed handle 122.

[0037] The shell 10 further comprises a rolling brush cover portion 5. The rolling brush cover portion 5 is arranged on the front side of the water tank portion 1 and is in an arc-shaped structure. The rolling brush cover portion 5 blocks the upper side of the rolling brush of the surface cleaning equipment to avoid the dirt rolled up by the rolling brush from being thrown out.

[0038] The bottom wall 13 further comprises at least one electrolysis assembly 50 for electrolyzing the cleaning fluid in the liquid storage cavity 11 to improve the cleaning effect of the cleaning fluid.

[0039] The working principle of the present application is as follows: when it is needed to add cleaning fluid into the liquid storage cavity 11, the water supply tank device 100 is detached from the surface cleaning equipment, and is then turned over to place the bottom wall 13 upward; the release knob 40 is pushed to slide from the first position to the second position, the water filling cover 30 is unlocked with the release knob 40, the release knob 40 is loosened after the water filling cover 30 is opened, and at this time the water filling opening 132 is open to add cleaning fluid into the liquid storage cavity 11 by the user. After the supplement is completed, the release knob 40 is pushed to slide from the first position to the second position, and the water filling cover 30 is closed, the release knob 40 is loosened when the water filling cover 30 completely covers the water filling opening 132, the reset release knob 40 is inserted with the locking portion 3 on the water filling cover 30, and then the water supply tank device 100 is installed on the surface cleaning equipment.

[0040] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the present application.
