Description

Technical Field

[0001] The utility model relates to a detection mechanism, in particular to an operation detection mechanism of a medical fabric drying machine. Background Art

[0002] Medical fabrics can generally be categorized as common textiles, non-woven fabrics, knitwear, and specialty fabrics (such as perforated fabrics with excellent breathability, which can be used in medical products like skin patches). Some medical fabrics can be reused, but during this process, they must be cleaned, disinfected, and dried to prevent cross-contamination. Drying is typically done in a dryer, which reduces the possibility of external contamination and ensures better cleanliness. Large dryers are used to dry medical fabrics, where hot air, after heat exchange, flows across the surface of the fabric, removing moisture from the fabric and ultimately drying the garment. Dryers typically use exhaust ventilation, creating a negative pressure inside the dryer, which forces airflow from top to bottom. Monitoring the dryer's operating status is crucial to prevent components like the heat pump from continuing to operate in the event of a malfunction in the dryer's hot air system, potentially shortening the dryer's service life. Utility Model Content

[0003] The purpose of the utility model is to provide an operation detection mechanism for a medical fabric dryer, which can detect whether the hot air system of the dryer is in a normal operating state, thereby extending the service life of the dryer.

[0004] The technical solution of the utility model is as follows: a medical fabric dryer operation detection mechanism includes a detection port arranged on the side wall of the negative pressure chamber of the dryer body, a mounting seat is provided on the upper side of the detection port, a support rod that can rotate relative to the mounting seat is provided in the mounting seat through a mounting axis, a contact switch is provided on the inner side of the mounting seat, and a baffle is provided at the lower end of the support rod through a universal connector. When the dryer is in normal operation, the baffle can be adsorbed on the detection port and seal the detection port, and the support rod will trigger the contact switch at the same time; when the negative pressure of the dryer is reduced, the baffle can be separated from the detection port under the action of gravity, and the support rod is separated from the contact switch.

[0005] In the aforementioned medical fabric dryer operation detection mechanism, the contact switch is a normally closed switch. The contact switch is in an open state when the baffle is adsorbed on the detection port, and is in a closed state when the baffle is separated from the detection port.

[0006] In the aforementioned operation detection mechanism for a medical fabric dryer, a plurality of mounting grooves are provided on the support rod.

[0007] In the aforementioned operation detection mechanism for a medical fabric dryer, a detachable counterweight is provided on the mounting groove.

[0008] Compared with the prior art, the present invention provides a detection port on the side wall of the negative pressure chamber of the dryer body, and a baffle at the detection port, so that under the action of the negative pressure generated by the normal operation of the dryer, the baffle can be adsorbed at the detection port, and the support rod drives the contact switch to disconnect. When the negative pressure in the dryer body decreases significantly, the baffle cannot be adsorbed at the detection port, and the contact switch is closed, so that the signal can be fed back to realize the detection of the operating status of the dryer.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0014] Embodiment. A medical fabric drying machine operation detection mechanism, comprising: Figure 1-2 As shown, it includes a detection port 1 arranged on the side wall of the negative pressure chamber of the dryer body, a mounting seat 2 is provided on the upper side of the detection port 1, a support rod 3 that can rotate relative to the mounting seat 2 is provided in the mounting seat 2 through a mounting axis 8, a contact switch 5 is provided on the inner side of the mounting seat 2, and a baffle 4 is provided at the lower end of the support rod 3 through a universal connector 9. When the dryer is in normal operation, the baffle 4 can be adsorbed on the detection port 1 and seal the detection port 1, and the support rod 3 will trigger the contact switch 5; when the negative pressure of the dryer is reduced, the baffle 4 can be separated from the detection port 1 under the action of gravity, and the support rod 3 is separated from the contact switch 5.

[0015] The contact switch 5 is a normally closed switch. When the baffle 4 is adsorbed on the detection port 1 , the contact switch 5 is in an open state. When the baffle 4 is separated from the detection port 1 , the contact switch 5 is in a closed state.

[0016] Principle of the present utility model: This application is used to detect the operation of hot air in the dryer. Generally, the greater the negative pressure in the negative pressure chamber of the dryer body, the greater the air volume. If the dryer fails to operate, it is easy for external air to directly enter the dryer body and contaminate medical fabrics. This application is achieved by providing a detection port on the side wall of the negative pressure chamber of the dryer body, and providing a mounting seat 2 on the upper side of the detection port 1. The mounting seat 2 is provided on the outside of the dryer body and is directly above the detection port 1. A support rod 3 that can rotate relative to the mounting seat 2 is provided in the mounting seat 2, and a baffle 4 is provided at the lower end of the support rod 3. In the absence of external force, the support rod 3 droops under the action of gravity, the baffle 4 does not contact the detection port 1, and the support rod 3 does not touch the contact switch 5. After the dryer is started, the support rod 3 is rotated so that the baffle 4 under the support rod 3 can be adsorbed on the detection port 1 under the action of the negative pressure in the dryer body, and the support rod 3 will trigger the contact switch 5, so that the contact switch 5 is in the off state. When the dryer body fails to operate, the negative pressure in the negative pressure chamber of the dryer body decreases. When the suction force generated by the negative pressure is insufficient, the support rod 3 will swing downward under the action of gravity, the baffle 4 will separate from the detection port 1, and the support rod 3 will move away from the contact switch 5, and the contact switch 5 will return to the closed state. The contact switch can further be connected to an external alarm or signal circuit, etc., to feed back the negative pressure state to the outside, notifying the staff to shut down the dryer for inspection to avoid further damage to the dryer.

[0017] Example 2. The structure is as follows Figure 3 As shown, based on Example 1, the support rod 3 is provided with multiple sets of mounting slots 7, each of which is provided with a removable counterweight 6. The counterweight 6 is secured to the mounting slots 7 by means of fasteners such as pins and screws. Because some dryers have an air volume adjustment function, the negative pressure within the negative pressure chamber of the dryer body may vary. When the air volume adjustment causes the negative pressure within the dryer to increase, if the total weight of the support rod 3, baffle 4, etc. remains unchanged, then when the hot air system malfunctions and the suction force decreases, the baffle 4 will still be attracted to the detection port 1. This application cannot accurately detect and feedback the operating status. Therefore, the counterweight 6 can be removed or installed in the mounting slots 7 of the support rod 3 and secured with screws or other components. Since the initial state used in this application is that the baffle 4 is located at the detection port 1, the support rod 3 is tilted and the angle is constant. The change in the support rod's gravity will affect the suction force generated by the negative pressure chamber on the baffle 4 when the baffle is attracted to the detection port 1. By adjusting the weight, the baffle 4 is matched to the negative pressure within the dryer, thus improving its applicability.
