Description

Technical Field

[0001] This utility model relates to the field of nursing robot technology, and in particular to a clean water tank for a nursing robot. Background Technology

[0002] To improve the care of bedridden patients or the elderly, various intelligent nursing devices have emerged on the market to reduce the burden on caregivers and effectively improve the patient's treatment environment. However, the water purification devices of nursing robots generally separate the water purification tank and the water storage tank, connecting them via a water pump during rinsing. Other designs integrate the purification and storage into a single water purification tank, placing the tank deep within the outer container. This makes cleaning the interior difficult, leading to secondary contamination and bacterial growth. For example, CN 112832328 A discloses a water purification tank and water storage device for a nursing robot: a tank body, a water purification tank lid, and a sealing ring; the water purification tank lid is located on the tank body and has a stop valve for controlling water flow. However, this solution has the following problems: its sterilization and disinfection components and heating module are located in the external circulation system, preventing internal water circulation within the purification tank, and it is also costly.

[0030] like Figure 1 and Figure 2 As shown in this embodiment, a clean water tank for a nursing machine includes:

[0031] The system comprises a water tank body 1, an upper cover 2, and a piston lower cover 3. The water tank body 1 has an inlet 11 at its upper part, which is sealed to the upper cover 2. The lower part of the water tank body 1 has two outlets 12, each connected to a piston lower cover 3, which contains a built-in piston structure 4. Water is added to the water tank body 1 by opening the upper cover 2. The two outlets 12 at the bottom of the water tank body 1 are designed with one inlet and one outlet, working in conjunction with an external sterilization module and water pump to achieve efficient water purification and internal water circulation without the need for an additional water storage tank. Furthermore, the bottom outlets 12 are connected to the piston lower cover 3, which enables a contactless water circuit switch. The piston structure 4 controls the piston lower cover to be open or closed, allowing for free control of water flow from and out of the purified water tank, making it convenient for users to remove water from the machine for refilling.

[0032] Furthermore, in this embodiment, a handle structure 13 is also provided on one side of the water tank body 1. This design facilitates the user's carrying of the tank for water changes.

[0033] Furthermore, in this embodiment, the water tank body 1 has recessed limiting grooves 5 on both sides. This recessed limiting groove on one side of the water tank body helps to stabilize the water tank.

[0034] Furthermore, in this embodiment, the upper part of the limiting slot 5 is configured as an arc-shaped structure.

[0035] Furthermore, in this embodiment, the limiting slot 5 is also provided with an inductive magnet 6 that is conductively connected to an external sensor. Installing the inductive magnet 6 on the limiting slot 5 facilitates automatic detection of the water tank's position and attitude by cooperating with the detection sensor, thus preventing the water tank from tilting.

[0036] Furthermore, in this embodiment, the upper cover 2 is comprehensively provided with anti-slip parts 21. This design facilitates better grip when unscrewing or closing the cover, preventing slippage and making it easier for users to lift the tank and change the water.

[0037] Furthermore, in this embodiment, as Figure 3 As shown, the piston lower cover 3 also includes: a spring 31, a lower cover washer 32 and a lower cover 33. The lower cover washer 32 is fixed in the circumferential groove 37 of the lower cover 33. The spring 31 is installed on the piston structure 4 and the piston structure 4 is installed in the middle of the lower cover 33.

[0038] Furthermore, in this embodiment, the piston lower cover 3 is provided with a recessed mounting groove 34 in the middle, and the mounting groove 34 is provided with uniformly distributed through holes 35, and the piston structure 4 is installed in the mounting groove 34.

[0039] Furthermore, in this embodiment, as Figure 4 As shown, the piston structure 4 includes a piston part 41, a limiting rod 42, and a limiting part 43. The piston part 41 is mounted on the mounting groove 34. The limiting rod 42 passes through the through hole 36 in the middle of the mounting groove 34. One end of the limiting rod 42 is connected to the piston part 41, and the other end is connected to the limiting part 43. The limiting part 43 is mounted at the bottom of the mounting groove 34.

[0040] Preferably, in this embodiment, the spring 31 is wound around the limiting post 42.

[0041] Preferably, in this embodiment, such as Figure 5 As shown, with the water bucket externally positioned, the piston structure 4 is held in place by the tension of the spring 31 on the lower cover gasket 32, preventing water leakage at the bottom.

[0042] Preferably, in this embodiment, such as Figure 6 As shown, the water bucket is placed inside the machine. Due to the water tank being stuck and the weight of the water, the piston structure 4 is pushed open by the protrusion inside the machine, thus opening the water passage.

[0043] Compared with the prior art, this application has the following technical effects:

[0044] In this application, water is added to the water tank by opening the top cover. The two water outlets at the bottom of the water tank are designed with one inlet and one outlet, which, together with the external sterilization module and water pump, can achieve efficient water purification and internal water circulation without the need for an additional water storage tank. Furthermore, the bottom outlet is connected to the piston cover, which enables a contactless water circuit switch. The piston can control the piston cover to be open or closed, allowing users to freely control the water output from the purified water tank and turn it off. This makes it convenient for users to remove water from the machine and add more water.

[0045] In this application, by providing an anti-slip part on the top cover, it is beneficial to exert more force when unscrewing or closing the top cover to prevent slippage and make it convenient for users to lift the tank to change water. At the same time, the recessed limiting groove on one side of the water tank body helps to make it easy to place the water tank stably.

[0046] In this application, an inductive magnet is installed on the limit slot, which is beneficial to automatically detect the position and attitude of the water tank by working with the detection sensor, thus preventing the water tank from tilting.

[0047] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. The application has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application, and all such modifications and substitutions should be covered within the scope of the claims of this application.
