An embodiment of the application discloses an endoscope wiper mechanism for rinsing endoscope 600. The endoscope 600 is usually made of glass or organic plastic, and when the endoscope 600 is cleaned, the cleaning force should be appropriate, if the endoscope is cleaned by using a high-pressure water beam with a water pressure of 20-30MPa, or the endoscope 600 is cleaned by using a brush structure rotating at a high speed (e.g., a rotation speed of 60-90 rpm), the surface of the endoscope 600 is scratched by the high-pressure water beam or the brush rotating at a high speed, but the endoscope 600 can be cleaned gently by using a brush structure rotating at a low speed (e.g., a rotation speed of 10-30 rpm).

As shown in fig. 1, the cleaning mechanism of the endoscope has a cleaning chamber 100, and when the endoscope 600 is cleaned, the endoscope 600 is put into the cleaning chamber 100, and the cleaning mechanism of the endoscope is started to automatically clean the endoscope 600.

The endoscope cleaning mechanism in this embodiment further includes: pump body 200, hollow shaft 300 and cleaning brush assembly 400, wherein pump body 200 is located outside cleaning chamber 100, hollow shaft 300 is installed in cleaning chamber 100, and a part of the hollow shaft 300 extends out of cleaning chamber 100 and is connected with pump body 200, pump body 200 is used for delivering cleaning liquid into hollow shaft 300, and cleaning liquid delivered by pump body 200 has certain pressure and flow rate (the water pressure is about 10-15 MPa), but the cleaning liquid is not high-pressure water beam. The hollow shaft 300 is rotatably mounted at both ends thereof to the two outer walls of the cleaning chamber 100, and is rotatably connected by means of bearings. The cleaning brush assembly 400 is located in the cleaning chamber 100, connected to the hollow shaft 300 and communicated with the hollow shaft 300, and a water spraying hole 412 is opened on the cleaning brush assembly 400, and since the cleaning brush assembly 400 is communicated with the hollow shaft 300, cleaning with a certain pressure and flow rate in the hollow shaft 300 also enters the cleaning brush assembly 400 and is sprayed out from the water spraying hole 412 at a certain speed, and the cleaning brush is pushed to rotate by the reaction force of the spraying. The endoscope cleaning mechanism in this embodiment does not need to be provided with a motor, but the pump body 200 is used to deliver a cleaning solution with a certain pressure, the cleaning solution is sprayed out from the water spray holes 412 through the hollow shaft 300, and the water outlet direction of the water spray holes 412 is clockwise or counterclockwise around the circumference of the hollow shaft 300; when the water spraying is realized, the cleaning brush assembly 400 is pushed to rotate by the reaction force of the water spraying, the endoscope 600 in the cleaning cavity 100 is cleaned, and the cost is greatly saved.

It should be noted that the washing brush assembly 400 is disposed on the hollow shaft 300, and it is only necessary that the washing brush assembly 400 is communicated with the hollow shaft 300 in this embodiment, unlike the conventional washing brush fixedly connected to the end of the output shaft of the motor, and therefore, the washing brush assembly 400 may be disposed at any position of the hollow shaft 300, and may be located at the middle or end. The number of the washing brush assemblies 400 in this embodiment is greater than or equal to two, and the respective washing brush assemblies 400 are arranged in line in the axial direction of the hollow shaft 300. Since the washing brush assembly 400 is not required to be provided at the end of the hollow shaft 300, a plurality of washing brush assemblies 400 may be provided on the shaft body of the hollow shaft 300, thereby improving washing efficiency.

Specifically, referring to fig. 1 and 2, the washing brush assembly 400 includes: the support 410 is connected to the hollow shaft 300 and communicated with the hollow shaft 300, the water spraying holes 412 are formed in the support 410, and water of the hollow shaft 300 is sprayed out through the water spraying holes 412 in the support 410 to push the support 410 and the hollow shaft 300 to rotate synchronously. The brush body 420 is coupled to the bracket 410 to clean the parts to be cleaned in the cleaning chamber 100 as the bracket 410 rotates. The number of the brush bodies 420 may be 1 or more, and the brush bodies 420 may be disposed at various positions on the holder 410, and each brush body 420 may face one side or may face different directions, so as to perform overall brushing on the surface of the endoscope 600. In this embodiment, the brush bodies 420 are arranged on a side of the bracket 410 away from the hollow shaft 300, and the brush head portion is away from the bracket 410. The side of the bracket 410 away from the hollow shaft 300 has the longest rotational path, the longest moving distance of the brush head, and the largest cleaning area. Of course, in other embodiments, the brush body 420 may be disposed in other manners, and is not limited in this embodiment. It can be understood that the brush body 420 is disposed on the top surface of the support 410 away from the hollow shaft 300, and the hollow shaft 300 drives the brush body 420 to rotate by the water spraying reaction force of the support 410, so as to perform overall brushing on the surface of the endoscope 600. And the cleaning liquid sprayed from the spray holes 412 has a function of uniformly spraying in addition to providing the rotating power of the hollow shaft 300.

The brush body 420 is made of a non-metal anti-corrosion material, preferably PFA plastic; polybutylene terephthalate (PBT), PA plastic, PP plastic and PE plastic are selected alternatively, and the plastics have good performance and defects and can be selected according to actual conditions. PFA is corrosion resistant and high temperature resistant; PBT has good elasticity but poor wear resistance; the PA has good abrasion resistance, high temperature acid and alkali resistance and the like, but the PP with higher cost has acid and alkali resistance and the like, but the PP has general elasticity, is easy to deform and difficult to deform after long-time work; PE is relatively soft and is commonly used in automobile cleaning brushes. But is not limited to the above materials.

As shown in fig. 2 and 3, the bracket 410 is a hollow bracket body 411, the hollow shaft 300 is provided with water leakage holes 330, the water leakage holes 330 are communicated with the bracket 410, the cleaning solution enters the bracket 410 from the water leakage holes 330 in the hollow shaft 300, and is sprayed out from the water spray holes 412 in the bracket 410 after the bracket 410 is filled with the cleaning solution, so as to provide torque for the bracket body 410 and push the cleaning brush assembly 400 to rotate around the central axis of the hollow shaft 300; the jetted water flow applies force to the holder 410 to rotate the holder 410 and the washing brush assembly 400. The brackets 410 are arranged along the circumference of the hollow shaft 300, and the brackets 410 rotate around the axis of the hollow shaft 300, and may rotate clockwise or counterclockwise along the axis of the hollow shaft 300. Therefore, based on the force arm stress, the central axis of the water spraying hole 412 is perpendicular to the plane different from the central axis of the hollow shaft 300, that is, the emitting direction of the water spraying hole 412 is parallel to the circumferential tangent of the hollow shaft 300, so that the low-pressure water can be used for driving the hollow shaft 300 to rotate. The bracket 410 has a first side and a second side in a rotation direction, wherein the first side and the second side are opposite to each other, and when the bracket 410 rotates in a direction, the first side or the second side can face or depart from the rotation direction. In one embodiment, the bracket 410 is disposed on one side of the hollow shaft 300, water in the hollow shaft 300 is sprayed through the water spraying holes 412 on the bracket 410, the bracket 410 and the hollow shaft 300 are pushed to rotate together, the water spraying holes 412 are disposed on the first side or the second side, if the water spraying holes 412 are sprayed from the first side, the sprayed water reversely pushes the bracket 410, and the bracket 410 rotates along the direction away from the first side; if the water jet holes 412 are sprayed from the second side, the sprayed water pushes the bracket 410 in a reverse direction, and the bracket 410 rotates in a direction away from the second side. The direction of rotation of the bracket 410 is therefore determined by the location at which the water jet holes 412 are formed.

In another embodiment, the bracket 410 includes: at least two support bodies 411, each support body 411 sets up around hollow shaft 300, all is provided with brush body 420 on each support body 411, and when support 410 rotated, the brush body 420 on each support body 411 was treated clean scope 600 in proper order and is cleaned, promoted cleaning efficiency. When the bracket 410 rotates, the rotation direction of each frame body 411 must be the same, otherwise, the thrust cancellation situation occurs. The rotation direction of the frame 411 is determined by the position and direction of the water spraying holes 412, wherein the cleaning liquid sprayed from the water spraying holes 412 is perpendicular to the frame 411, so as to achieve the best driving effect. As shown in fig. 4, when the arrows indicate the water flow direction, the water spraying holes 412 on the frame 411 are disposed on one side, a torque is provided to the frame 411 to rotate the frame 411 in one direction, and further, the torque provided by the water spraying holes 412 on each frame 411 is in the same direction to rotate the frame 410 in a reverse direction. The rotational speed of the carrier 410 is preferably: 20r/min-60r/min, preferably 30 r/min.

The frame body 411 includes: the water storage device comprises an outer wall 413 and a plurality of water storage cavities 414, wherein the outer wall 413 is provided with a plurality of water storage cavities 414 which are defined by surrounding, water spraying holes 412 are formed in the outer wall 413, the water storage cavities 414 are communicated with the hollow shaft 300, and when water is delivered, water in the hollow shaft 300 is filled in the water storage cavities 414 and then is sprayed out from the water spraying holes 412 in the outer wall 413. The diameter of the water spray hole 412 is preferably 1 mm; if the aperture is smaller than 1mm, the processing cost of the cleaning brush mounting bracket 410 is increased, and if the aperture is larger than 2mm, the rotating speed of the spray arm is too slow, so that the surface of the soft endoscope 600 is difficult to clean. The blowhole 412 has: a first end facing the water storage cavity 414 and a second end facing away from the water storage cavity 414, wherein the aperture of the first end is larger than that of the second end. The inner diameter of the spraying end of the water spraying hole 412 is smaller, sprayed water flow is more concentrated, the water flow speed is higher, pressure is higher, the pushing force on the frame body 411 is larger, and the driving effect is better.

When the bracket 410 rotates, the rotating speed is influenced not only by the speed of the sprayed water flow but also by the weight of the bracket 410, and the larger the weight of the bracket 410 is, the larger the gravity and the rotation resistance are, and the slower the rotating speed is. The smaller the weight of the bracket 410, the faster the speed of rotation. And after the rotation of the support 410 is smooth, the greater the weight of the support 410, the better the stability of the speed of rotation. Therefore, when the water spraying holes 412 start to spray water and rotate, the bracket 410 is filled with cleaning solution, in this embodiment, as shown in fig. 5, a partition 415 is arranged in the water storage cavity 414 of the frame body 411, the partition 415 is transversely or obliquely arranged in the water storage cavity 414 to divide the water storage cavity 414 into a first part 4141 and a second part 4142, a connecting channel exists between the first part 4141 and the second part 4142 which are divided by the partition 415, wherein the first part 4141 is communicated with the water spraying holes 412 and the hollow shaft 300, and the second part 4142 is a hollow cavity. Because the partition 415 divides the water storage cavity 414 into two parts, the cleaning liquid in the hollow shaft 300 can directly enter the first part 4141 and be sprayed out from the water spraying holes 412, and the cleaning liquid does not enter the second part 4142, so that when the water spraying holes 412 of the frame body 411 spray water, the cleaning liquid does not need to be filled in the whole water storage cavity 414, and only the first part 4141 needs to be filled, thereby reducing the weight of the frame body 411 during water spraying, improving the rotating speed and the force, and further improving the cleaning efficiency. The arrangement of the partition 415 enables the second portion 4142 not to store cleaning solution therein, in some embodiments, the rack 411 may be configured in a special shape, so that the space of the water storage cavity 414 in the rack 411 is small, but the shape of the rack 411 is special-shaped, which may affect the rotation effect of the rack 411, in this embodiment, the rack 411 is configured with the partition 415, so that the cleaning solution does not need to fill the rack 411 under the condition of ensuring the stability of the external shape, the weight of the rack 411 is reduced, and the rotation speed and the cleaning efficiency are improved. Meanwhile, after the bracket 410 rotates stably, the cleaning solution flows into the second portion 4142 through the connecting channel due to the rotational inertia of the cleaning solution in the bracket body 411, so that the cleaning solution is filled in the second portion 4142, the weight of the bracket 410 is increased, the inertia is provided for the rotation of the bracket 410, and the speed stability of the bracket 410 is better. Wherein the spacing of the connecting channels is between 0.1mm and 2mm, cleaning fluid cannot fill the second portion 4142 under non-stressed conditions, the cleaning fluid only flows into the first portion 4141; after the frame 411 rotates, the cleaning solution is forced to fill the second portion 4142 due to inertia.

When installed, the first portion 4141 is located on a side away from the hollow shaft 300 and the second portion 4142 is located adjacent to a side of the hollow shaft 300. And more than two blowholes 412 are arranged on the same straight line; the straight line is a center line of the outer wall 413; alternatively, the straight line is located at an end of the outer wall 413 remote from the hollow shaft 300. When the straight line is a center line of the outer wall 413, it is ensured that at least one water spraying hole 412 still sprays water when the water pressure is low. When the straight line is located at an end of the outer wall 413 away from the hollow shaft 300, the hollow shaft 300 may be pushed to rotate even when the water pressure is low.

As shown in fig. 1 and 2, the hollow shaft 300 includes a first cavity, the pump body 200 includes a water outlet, and the water outlet is connected with a water inlet pipe 210 communicated to the first cavity; that is, the side of the hollow shaft 300 located outside the washing chamber 100 is connected to the water inlet pipe 210, the side of the hollow shaft 300 located outside the washing chamber 100 is connected to the connector 220, and the connector 220 is hermetically connected to the water inlet pipe 210.

The hollow shaft 300 and the connecting shaft can rotate relatively, the connecting head 220 is sleeved on the hollow shaft 300, and the hollow shaft 300 can rotate in the connecting head 220. Specifically, a rotary sealing ring 221 is disposed between the connector 220 and the inner walls of the hollow shaft 300 and the connector 220. The rotary sealing ring 221 is an O-shaped ring or an X-shaped sealing ring, is sealed in a rotating mode, is stretched by 5% -7%, and the rotary sealing ring 221 ensures no compression amount and can freely rotate. As shown in fig. 4, the bracket 410 includes a sleeve 416 sleeved outside the hollow shaft 300 and at least two frame bodies 411, the frame bodies 411 are uniformly distributed on the surface of the sleeve 416, each frame body 411 is arranged around the hollow shaft 300, and when the hollow shaft 300 rotates by an angle, the positions of the frame bodies 411 are overlapped with each other; at least one water spraying hole 412 is formed in the surface of one side of the frame body 411; a second cavity is arranged in the sleeve 416 and communicated to the first cavity of the hollow shaft 300; a third cavity is arranged in the frame body 411 and communicated to the second cavity.

The anti-rotation slots 320 are fixedly connected with the support 410, so that the support 410 is fixed with the hollow shaft 300 and can rotate synchronously, and the phenomenon that the air shaft and the support 410 rotate relatively to generate a water leakage groove and the water storage cavity 414 are staggered is avoided. In addition, a plug is disposed at an end of the hollow shaft 300 away from the pump body 200, and the plug is used for sealing the hollow shaft 300 and preventing water from leaking from the position of the hollow shaft 300 except the water leakage hole 330. The outer diameter of the plug is larger than the outer diameter of the hollow shaft 300, and the plug is detachably connected to the hollow shaft 300, and may be in a bolt connection or an interference fit, which is not limited in this embodiment.

And the pump body 200 cannot be replaced with a motor, otherwise the means for supplying the cleaning fluid would be absent; if a motor is added to drive the hollow shaft 300 to rotate, the hollow shaft 300 needs to be adjusted to a slow rotation speed, which not only increases energy consumption, but also reduces the pressure of the cleaning solution supplied by the pump body 200. The cleaning solution sprayed from the water spraying holes 412 of the cleaning brush assembly 400 arranged on the hollow shaft 300 is comprehensively considered to have the function of even spraying besides the rotation power of the hollow shaft 300, the water spraying holes 412 are set to be of a structure with a large inner diameter and a small outer diameter, and when enough power for pushing the hollow shaft 300 is provided, the sprayed cleaning solution is in a foggy state and is evenly sprayed on the endoscope 600, the cleaning brush body 420 is matched to slowly scrub, and the endoscope 600 is guaranteed not to be scratched when the endoscope 600 is cleaned. Therefore, the pump body 200 can supply cleaning liquid and provide power for rotating the hollow shaft 300, and an additional motor is not needed, so that the structure is optimized and energy is saved.

During cleaning, the bottom side of the cleaning chamber is provided with the recovery area 230, the recovery area 230 is located below the tray 500, and the recovery area 230 is connected with the pump body 200 through the recovery pipe 231, so that the cleaning liquid for cleaning the endoscope 600 can return to the pump body 200 through the recovery pipe 231 and enter the cleaning chamber 100 again through the water inlet pipe 210 to clean the endoscope 600, and the utilization rate of the cleaning liquid is improved.
