Description

Technical Field

[0001] The utility model belongs to the technical field of floor scrubbers, and in particular relates to a water storage tank used in conjunction with a clean water tank of a top water-suction floor scrubber. Background Art

[0002] A floor scrubber is a vertically installed cleaning device that combines vacuuming and floor washing. It is mainly composed of a handle assembly, a body assembly, and a cleaning head assembly. The body assembly includes a body, a clean water tank, a sewage tank, a water pump, a power assembly, and a control panel; the cleaning head assembly includes a cleaning roller brush, a scraper, a motor, and a clean water spraying system. When the floor scrubber is working, the water in the clean water tank is sprayed onto the roller brush made of a rag. The roller brush contacts the ground and runs at high speed to clean the dirty ground and absorb the dust onto the roller brush. At the same time, the scraper scrapes the sewage off the roller brush, and the scraped sewage is sucked into the sewage tank, thereby completing the floor cleaning process.

[0003] In the prior art, most floor scrubbers use a bottom water outlet, that is, a water outlet is set at the bottom of the water tank. When the floor scrubber is working, the outlet valve of the outlet is opened, and the water in the water tank is injected into the outlet pipe by the gravity of the water, and then sprayed onto the roller brush through the water pump. Since the outlet is set at the bottom of the water tank, the bottom of the water tank will leak after a period of use, so a top water suction floor scrubber has emerged to solve the problem of water seepage at the water outlet of the water tank.

[0004] However, most of the existing top-suction floor scrubbers use a water pump to directly suck water from the clean water tank upwards and then spray it onto the roller brush. When the floor scrubber stops working and needs to be filled with clean water, the clean water tank needs to be taken out. In the process of taking out the clean water tank, the water outlet of the clean water tank and the water pipe connected to the water pump need to be separated. At this time, after the clean water tank is taken away, reflux water in the water pipe connected to the water pump will still drip onto the installation surface of the clean water tank, thereby wetting the electronic components on the installation surface, further causing damage to the floor scrubber.

[0024] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0025] The following describes in detail a water storage tank used in conjunction with a clean water tank of a top water-suction floor scrubber according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0026] like Figure 1-4As shown, the embodiment of the utility model provides a water storage tank for use with a clean water tank of a top water-suction floor scrubber, comprising: a water storage tank body 1, the upper end of the water storage tank body 1 is opened to form a water storage chamber 12, a vertically arranged water inlet pipe 11 is fixedly arranged on the outer wall of the water storage tank body 1, the upper end of the water inlet pipe 11 is a water inlet pipe outlet 111, and the lower end is a water inlet pipe inlet 112, a notch 13 is provided at the upper end of the water storage tank body 1 adjacent to the water inlet pipe outlet 111, the water inlet pipe outlet 111 is communicated with the water storage chamber 12 through the notch 13, and the water inlet pipe inlet 112 is used to seal and communicate with the clean water tank outlet;

[0027] The end cover 2 is sealed and connected to the upper opening of the water storage tank body. A water outlet pipe 21 is passed through the end cover. The lower end of the water outlet pipe 21 extends to the bottom of the water storage chamber 1. The upper end of the water outlet pipe 21 is used to connect with the water pipe of the water pump.

[0028] Specifically, a support member 14 is fixedly provided at the bottom of the water tank body 1, and the support member 14 is arranged side by side with the water inlet 112 of the water inlet pipe. The bottom of the support member 14 is lower than the water inlet 112 of the water inlet pipe, so that the top surface of the clean water tank and the water inlet 112 of the water inlet pipe are in a suspended state when the clean water tank is installed and removed, thereby protecting the seal from damage.

[0029] Furthermore, the support member is V-shaped, and has a first inclined surface 141 and a second inclined surface 142 symmetrically arranged, wherein the first inclined surface 141 is away from the water inlet 112 of the water inlet pipe, and the second inclined surface 142 is adjacent to the water inlet 112 of the water inlet pipe.

[0030] Specifically, a guide platform 1421 is provided on the second inclined surface 142, and the area of ​​the guide platform 1421 is smaller than that of the second inclined surface 142. The guide platform 1421 has a third inclined surface and a fourth inclined surface arranged opposite to each other. The third inclined surface is close to the water inlet 112 of the water inlet pipe, and the fourth inclined surface is far away from the water inlet 112 of the water inlet pipe. The inclination angle of the third inclined surface is smaller than the inclination angle of the fourth inclined surface. The guide platform 1421 can reduce the friction between the top surface of the clean water tank and the second inclined surface 142 when pulling out the clean water tank, thereby facilitating the start-up and pulling out of the clean water tank and playing a guiding role in pulling out the clean water tank.

[0031] Specifically, a sealing member 15 is provided at the water inlet 112 of the water inlet pipe, and the water inlet 112 of the water inlet pipe is sealedly connected to the water outlet of the clean water tank through the sealing member 15 .

[0032] Specifically, at least one column 22 is fixedly provided on the upper surface of the end cover, and each column 22 is sleeved with a spring 23. The lower end of the spring 23 abuts against the upper surface of the end cover 2, and the upper end of the spring 23 abuts against the body of the floor scrubber. The spring 23 is used to provide elastic force for the installation and removal of the clean water tank.

[0033] Specifically, two symmetrically arranged mounting portions 16 are provided on the outer wall of the water storage tank body 1 , and a through hole 161 is provided on the mounting portion 16 . The water storage tank body 1 is mounted on the body of the floor scrubber by means of screws passing through the through hole 161 .

[0034] Specifically, a guide plate 113 is provided on one side of the upper end of the water inlet pipe, the lower end of the guide plate 113 extends toward the water inlet 112 of the water inlet pipe, and the upper end of the guide plate 113 extends to the bottom of the notch 13, and the water in the water inlet pipe 11 flows into the water storage chamber 12 through the guide plate 13.

[0035] Specifically, an annular groove 17 is formed on the top surface of the water storage tank body 1 , and an annular boss 24 matching with the annular groove 17 is formed on the bottom surface of the end cover, so that the end cover 2 and the water storage tank body 1 are sealed and connected.

[0036] Specifically, the water tank body 1, the water inlet pipe 11 and the support member 14 are integrally injection molded.

[0037] After the above technical scheme is adopted, the beneficial effects of the utility model are as follows: first, the utility model arranges a water storage tank on the top of the clean water tank of the floor scrubber, and a vertically arranged water inlet pipe 11 is arranged on the outer wall of the water storage tank body, the upper end opening of the water inlet pipe 11 is a water inlet pipe outlet 111, and the lower end opening is a water inlet pipe inlet 112, and the water in the water storage chamber 12 is injected through the water inlet pipe outlet 111. Since there is no through hole such as a water inlet or a water outlet at the bottom of the water storage chamber 12 that is connected to the outside of the water storage chamber 12, when the floor scrubber stops working, the water flowing back in the water pipe flows back into the water storage chamber 12 through the water outlet on the water storage tank, and the flowing back water is stored in the water storage chamber 12 and cannot flow out from the water inlet pipe inlet 112 further, thus solving the problem that the flowing back water drips onto the clean water tank installation surface, thereby wetting the electronic components on the installation surface, and further causing damage to the floor scrubber;

[0038] Secondly, when the clean water tank is installed on the body of the floor scrubber, the top of the clean water tank first abuts against the top of the first inclined surface 141 of the support member 14, and the top of the clean water tank slides to the bottom along the top of the first inclined surface 141. During this process, the spring 23 contracts due to the pressure of the clean water tank. Since the bottom of the support member 14 is lower than the position of the water inlet 112 of the water inlet pipe, the water inlet 112 of the water inlet pipe and the sealing member 15 are suspended in the air during this process. When the clean water tank is pushed to the installation position, the spring 23 restores its natural state and the force generated drives the water storage tank to move downward, directly connecting the water inlet 112 of the water inlet pipe with the water outlet of the clean water tank, thereby realizing a sealed connection between the water inlet 112 of the water inlet pipe and the water outlet of the clean water tank. The above technology is adopted to avoid the seal 15 at the water outlet of the clean water tank from rubbing against the body of the floor scrubber when installing the clean water tank. In the long run, the seal 15 will be deformed and worn, thereby reducing the sealing effect of the seal 15 and further causing the clean water tank of the floor scrubber to leak.

[0039] When the clean water tank is removed from the body of the floor scrubber, the top of the clean water tank abuts against the bottom of the second inclined surface 142 of the support member 14, and the top of the clean water tank slides toward the top along the bottom of the second inclined surface 142. Due to the function of the support member 14, the water inlet of the water inlet pipe and the seal are suspended in the air during this process until the clean water tank is completely removed. The above technology also avoids the seal 15 at the water outlet of the clean water tank from rubbing against the body of the floor scrubber when installing the clean water tank. In the long run, the seal 15 will be deformed and worn, thereby reducing the sealing effect of the seal 15, further causing the problem of water leakage in the clean water tank of the floor scrubber.

[0040] Finally, the floor scrubber adopts the water storage tank structure of the utility model. After the floor scrubber is started for the first time, the water storage tank will receive the reflux water in the water pipe so as to keep a small amount of water in the water storage chamber 12. When the floor scrubber is started again, the water in the water storage tank will immediately enter the water pipe, which can avoid the floor scrubber's false alarm. Because, if the floor scrubber is not equipped with a water storage tank, the water in the clean water tank cannot reach the water pipe immediately every time the floor scrubber is started, which will cause the alarm device of the floor scrubber to generate an alarm prompt of no water in the clean water tank even when the clean water tank is full of water.

[0041] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
