Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a sealed water tank structure and a cleaning base station. Background Technology

[0002] With the development of technology, cleaning robots are now widely used. Cleaning robots can automatically vacuum, sweep, and mop. After cleaning, the cleaning robot needs to return to the cleaning base station to clean the cleaning mop. Existing cleaning base stations are usually equipped with a clean water tank and a wastewater tank. The clean water tank is used to provide clean water. The cleaning base station sprays clean water onto the cleaning mop for cleaning. Then, the wastewater generated from cleaning the cleaning mop is recycled into the wastewater tank of the cleaning base station.

[0003] Existing base station water tanks mostly use a detachable cover structure, which has poor sealing performance. When using negative pressure vacuum to extract sewage, it is easy to cause extraction failure, affecting the cleaning efficiency.

[0004] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described below.

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] Reference Figures 1 to 3 This utility model provides a sealed water tank structure that can be applied to both sewage tanks and clean water tanks. It includes an integrally formed tank body 1 and a cover 2. The tank body 1 has at least one inlet 11 and one outlet 13. The cover 2 is fixedly connected to the tank body 1 and has an inlet 21 corresponding to and connected to the inlet 11. A first sealing element 12 is provided between the cover 2 and the tank body 1 to ensure a tight seal between them, reducing the possibility of poor airtightness at the connection point. A tank cover 3 is detachably connected to the cover 2 to close the inlet 21. The tank cover 3 seals the inlet 21, ensuring its airtightness and further guaranteeing the sealing performance of the sealed water tank structure.

[0025] In this embodiment, the one-piece structure of the water tank body is manufactured by blow molding. In other embodiments, the one-piece water tank body 1 can also be manufactured by injection molding or other processes.

[0026] Compared with conventional water tanks, the water tank body 1 of this utility model has three advantages: The first advantage is that the water tank body 1 is integrally molded, eliminating the need for multi-layer structure connections and preventing water or air leakage due to sealing connection issues of various structures; the second advantage is that it is integrally blow-molded, which has a lower cost for blow molding molds and relatively lower cost for blow molding materials, effectively reducing production costs; the third advantage is that the water inlet 11 and water outlet 13 of the blow-molded water tank body 1 are relatively smooth and burr-free, which is beneficial for sealing the seals.

[0027] Reference Figure 2 and Figure 3 The water tank body 1 has at least one water inlet 11 and one water outlet 13. In this embodiment, the water tank body 1 has one water inlet 11 and one water outlet 13. The water inlet 11 is located on the upper end face of the water tank body 1, and the water outlet 13 is located on the lower end face of the water tank body 1. The cover 2 is fixedly fastened to the upper end face of the water tank body 1.

[0028] A flange 22 is formed at the water inlet 21 of the cover 2. When assembling the cover 2, the flange 22 extends into the water inlet 11 of the water tank body 1. In this embodiment, a first sealing member 12 is disposed between the flange 22 and the water inlet 11, and the first sealing member 12 is interference-fitted with the water inlet 11 and the flange 22 to achieve a seal at the connection between the cover 2 and the water tank body 1. The first sealing member 12 can be a silicone sealing ring or other sealing structure, as long as it can achieve the above function.

[0029] Furthermore, a second sealing element 31 is fitted on the water tank cover 3. When the water tank cover 3 is installed at the water inlet 21, the second sealing element 31 is interference-fitted with the flange 22 to ensure the seal at the water inlet 21.

[0030] By setting a double seal with the first sealing element 12 and the second sealing element 31, a good seal is achieved between the water tank body 1 and the face cover 2, and between the face cover 2 and the water tank cover 3, which effectively ensures the sealing performance of the sealed water tank structure.

[0031] Furthermore, in this embodiment, the cover 2 is press-fitted and connected to the upper surface of the water tank body 1, and a handle 23 is formed on the cover 2. The press-fit connection applies pressure to ensure a tight bond between the cover 2 and the water tank body 1, forming a robust connection that effectively guarantees the stability of the connection between the cover 2 and the water tank body 1. Moreover, the press-fit connection does not require complex equipment and is simple to operate. Furthermore, the handle 23 can be formed simultaneously as needed during the press-fitting process of the cover 2 onto the water tank body 1, effectively simplifying the production process. The handle 23 on the cover 2 facilitates the handling of the sealed water tank structure, improving its ease of use.

[0032] Furthermore, when the sealed water tank structure is applied to a clean water tank, an umbrella valve 14 can be installed on the tank body 1. Existing clean water tanks typically use a water pump or gravity to pump water. During the water discharge process, the pressure inside the tank increases, potentially causing drainage difficulties. Installing the umbrella valve 14 on the sealed water tank allows external air to enter the tank body 1 during drainage, balancing the internal and external pressures in real time. This prevents the air pressure inside the tank body 1 from gradually falling below the external air pressure, thus avoiding drainage difficulties.

[0033] Based on the above-described sealed water tank structure, this utility model also provides:

[0034] A clean base station 4 includes a sealed water tank structure as described above.

[0035] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
