[0002] Cleaning is the basis for ensuring that instruments are clean and sterile. However, for some instruments with complex structures and narrow gaps, such as dead corners that cannot be reached by cleaning brushes, dirt and bacteria are often easily retained.

[0003] For example, some semi-enclosed instruments, such as non-detachable humidification tanks, are currently cleaned by first soaking them in a cleaning solution, and then scrubbing them with a brush or cotton swab. However, this method undoubtedly significantly increases the difficulty of the work. On the one hand, due to the complexity and particularity of the structure of the humidification tank, it is difficult for the cleaning brush to fully reach every corner for effective scrubbing. Due to structural limitations, the cleaning brush cannot be effectively scrubbed on the sides and top, resulting in dirt accumulation in these areas, which become a potential source of infection. On the other hand, repeated soaking and scrubbing operations also increase the tediousness and time-consuming nature of the work, which in turn affects the efficiency and quality of the cleaning work to a certain extent, and brings certain challenges and difficulties to the work of the disinfection supply room. Therefore, a cleaning head for cleaning the inner wall of the humidification tank is designed and produced here to solve the above problems. Utility Model Content

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0026] Embodiment, this embodiment provides a cleaning head for cleaning the inner wall of a humidifying tank, as Figure 1 and Figure 2 shown, including: a transmission rod 1 and a brush head. A receiving notch is opened at the bottom end of the transmission rod 1. The brush head includes a brush handle 3 and brush bristles 31. The brush bristles 31 are arranged circumferentially along the outer wall of the brush handle 3, that is, the brush bristles 31 are distributed in a circle along the outer wall of the brush handle 3. At least two groups of brush bristles 31 are provided and are distributed on both side positions of the brush handle 3;

[0027] A sliding hole is opened in the brush handle 3. A pin shaft 34 is rotatably arranged between the two side walls at the inner bottom of the receiving notch. The pin shaft 34 slidably passes through the inner wall of the sliding hole. When the brush handle 3 is in a vertical state, due to the influence of its own weight, the inner wall of the sliding hole of the brush handle 3 can freely slide along the outer wall of the pin shaft 34 to adjust the cleaning height of the brush bristles 31. As Figure 3 shown, when the transmission rod 1 is inclined away from the vertical direction, the brush handle 3 can also flip with the pin shaft 34 as the rotation center to adjust the cleaning direction of the brush bristles 31.

[0028] The brush bristles 31 on the long side side wall of the brush handle 3 are used to clean the inner bottom wall and the top wall of the humidifying tank; the brush bristles 31 on the short side side wall of the brush handle 3 are used to clean the inner radial side wall of the humidifying tank. In order to ensure that the brush handle 3 is distributed along the inner radial direction of the humidifying tank during the cleaning process, the position of the brush handle 3 needs to be restricted. Therefore, as Figure 1 shown, a positioning rod 23. A rectangular hole for the sliding insertion of the positioning rod 23 is axially opened in the transmission rod 1. The upper end of the positioning rod 23 slidably extends out of the upper opening of the rectangular hole, and a docking head 2 is fixed. A cross plug 21 is fixed on the side wall of the end of the docking head 2. The cross plug 21 can be docked with the cross slot of the tool head mounting seat of an electric screwdriver. The electric screwdriver provides rotational power for the cross plug 21. Through the transmission of the positioning rod 23, the transmission rod 1 is driven to rotate, providing rotational power for the brush head to make a circular motion.

[0029] The bottom end of the positioning rod 23 is passed through the opening below the rectangular hole to limit the position of the brush handle 3. Specifically, an extension portion is horizontally provided at the bottom end of the positioning rod 23. By providing the extension portion, the positioning rod 23 is prevented from being pulled out from the upper opening of the rectangular hole. A clamping block 24 is fixed to the bottom wall of the positioning rod 23, and a plurality of slots 33 are provided on the long side wall of the brush handle 3. When the long side wall of the brush handle 3 is in a vertical state, the positioning rod 23 is slid down along the rectangular hole, and the clamping block 24 can be inserted into the slot 33. The purpose of this design is to keep the brush handle 3 in a vertical state, so that the transmission rod 1 and the brush head can be smoothly inserted from the tank mouth of the humidification tank during cleaning.

[0030] After the brush head is fully inserted into the inner cavity of the humidification tank, the brush handle 3 of the brush head needs to be adjusted from a vertical state to a horizontal state and maintained in a horizontal state. The specific operation method is as follows: Figure 4 and Figure 5 As shown, the upper end of the transmission rod 1 is inserted into the filling port of the humidification tank, and the brush head is located in the tank. The humidification tank and the transmission rod 1 are first adjusted from a vertical state to a horizontal state, and the outer wall of the pin shaft 34 and the inner wall of the sliding hole of the brush handle 3 rotate relative to each other. The brush handle 3 is in a vertical state. At this time, the angle between the brush handle 3 and the transmission rod 1 is 90°, and the lower end of the brush handle 3 contacts the inner radial side wall of the humidification tank. A slot 2 32 is provided on the short side wall of the brush handle 3. The positioning rod 23 is slid along the rectangular hole, and the block 24 is inserted into the slot 2 32 at the corresponding position. With the positioning of the block 24, the inner wall of the sliding hole of the brush handle 3 will no longer slide and rotate relative to the outer wall of the pin shaft 34, and it will remain perpendicular to the transmission rod 1.

[0031] At the same time, a plug sleeve 22 is provided at the bottom of the joint 2, and a recessed portion that can be tightly plugged with the plug sleeve 22 is provided at the upper end of the transmission rod 1. When the block 24 is inserted into the slot 2 32 at the corresponding position, the plug sleeve 22 can be inserted into the recessed portion. In the absence of external force to remove it, the plug sleeve 22 will not be separated from the recessed portion, ensuring that the block 24 is stably inserted into the slot 2 32, thereby ensuring that the brush handle 3 and the transmission rod 1 remain perpendicular to each other. After the position of the brush handle 3 relative to the transmission rod 1 is fixed, the humidification tank and the transmission rod 1 in the horizontal state are adjusted to the vertical state. At this time, the brush handle 3 is adjusted from the vertical state to the horizontal state. As long as the brush handle 3 is rotated, the cleaning operation can be performed.

[0032] Furthermore, the slot one 33 and the slot two 32 are located between the two groups of bristles 31 , and do not affect the insertion of the block 24 into the slot one 33 or the slot two 32 .

[0033] The specific cleaning process is as follows: Insert the brush head longitudinally into the humidifying tank along with the transmission rod 1. In the humidifying tank, adjust the brush handle 3 from the vertical state to the horizontal state, and fix the position of the brush handle 3 relative to the transmission rod 1 by clamping the block 24 into the slot two 32 at the corresponding position. It should be noted that when one end side wall of the brush handle 3 is in the horizontal state in the humidifying tank, the sliding hole of the brush handle 3 slides along the outer wall of the pin shaft 34, and a short side wall of the brush handle 3 contacts the radial side wall inside the humidifying tank. After the humidifying tank is adjusted to the vertical state, during the rotation of the brush handle 3, the bristles 31 on the short side wall of the brush handle 3 rotate to clean the radial side wall inside the humidifying tank.

[0034] Meanwhile, when the humidifying tank is in the vertical state, pull the transmission rod 1 up and down along the mouth of the humidifying tank, so that the long side wall of the brush handle 3 can be adjusted between the inner bottom wall and the top wall of the humidifying tank. When the brush handle 3 contacts the inner bottom wall of the humidifying tank, the bottom bristles 31 can clean the bottom wall of the tank during rotation. When the brush handle 3 contacts the inner top wall of the humidifying tank, the upper bristles 31 can clean the top wall during rotation.

[0035] It changes the way of long-time soaking cleaning in the prior art, realizes rapid and effective cleaning of each corner of the inner wall of the humidifying tank, and prevents dirt accumulation from becoming an infection source.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
