[0033] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 11 , the present invention provides a technical solution:

[0035] Embodiment 1, an ultrasonic probe disinfection device, comprises: a base 1, a mist exhaust fan 7 and a rotating base 8.

[0036] Specifically, a heart-shaped outer cylinder 2 is fixed on the upper surface of the base 1, the top of the outer cylinder 2 is sealed, an opening is provided at the front joint of the outer cylinder 2, and a sealing door 3 is installed at the opening through a hinge. Figure 1 and Figure 2 As shown, the sealing door 3 can be rotated to open or close, an arc plate 31 is fixed to the inner wall of the sealing door 3, and a mist shield 4 is provided in the inner cavity of the outer cylinder 2. The mist shield 4 is in a "C" shape, and the arc plate 31 and the mist shield 4 are spliced ​​into a circle. The mist shield 4 is made of a transparent quartz glass material, has a low absorption rate for ultraviolet light, allows ultraviolet light to penetrate, and can isolate water mist to prevent water mist from escaping outward:

[0037] ① When the sealing door 3 is opened, the arc plate 31 and the mist shield 4 are separated from each other, and the inner cavity of the mist shield 4 is opened;

[0038] ② When the sealing door 3 is closed, the arc plate 31 and the mist shield 4 are spliced ​​together to form a cylindrical shape. At this time, the inner wall of the mist shield 4 remains sealed and will not be connected with the inner cavity of the outer cylinder 2;

[0039] Secondly, the outer cylinder 2 is composed of two semi-elliptical shells spliced ​​together, and the focal points of one end of the two semi-ellipses coincide, the mist shield 4 is concentric with the focal point, and the other two focal points of the inner cavity of the outer cylinder 2 are provided with UVC ultraviolet lamps 6, such as Figure 3 The dotted line shown plus the left half of the outer cylinder 2 and a sealed door 3 together form an elliptical structure. A portion of the ultraviolet light emitted by the UVC ultraviolet lamp 6 directly irradiates the mist shield 4 and passes through the mist shield 4 to irradiate the probe body 5, and the other portion is reflected by the reflective layer 32 on the inner wall of the outer cylinder 2 and the sealed door 3 and then passes through the mist shield 4 to irradiate the probe body 5, thereby making full use of the ultraviolet light emitted by the UVC ultraviolet lamp 6. Since the reflected ultraviolet light can irradiate the probe body 5 at an angle different from that of the direct ultraviolet light, a single UVC ultraviolet lamp 6 can perform optical sterilization and disinfection on a larger area of ​​the surface of the probe body 5.

[0040] Furthermore, the mist exhaust fan 7 is located at the bottom of the mist shield 4 and is rotatably installed in the inner cavity of the base 1. The top of the outer cylinder 2 is fixedly connected with a water mist inlet pipe 16, and the water mist inlet pipe 16 is communicated with the inner cavity of the mist shield 4. The water mist inlet pipe 16 is communicated with an external atomization device. When the mist exhaust fan 7 rotates, the air in the inner cavity of the mist shield 4 is extracted to form a negative pressure in the inner cavity of the mist shield 4, and then the mist cleaning liquid (hereinafter referred to as water mist) used for cleaning is drawn into the mist shield 4 through the water mist inlet pipe 16 and attached to the surface of the probe body 5. Secondly, the exhaust fan 7 When the mist fan 7 rotates, the air in the inner cavity of the mist shield 4 is stirred to rotate and flow in a vortex shape, and the water mist follows the air in a vortex shape, thereby improving the cleaning effect on the surface of the probe body 5. After the cleaning is completed, the water mist is stopped, and only air is allowed to enter the inner cavity of the mist shield 4. The air flows to gradually dry the water mist on the surface of the probe body 5 and the water mist on the inner wall of the mist shield 4, thereby preventing the water mist from adhering to the inner wall of the mist shield 4 and the surface of the probe body 5, and the water mist from being retained in the inner cavity of the mist shield 4 to interfere with the irradiation of ultraviolet light;

[0041] In addition, the rotating seat 8 is rotatably mounted on the top of the outer cylinder 2, the inner cavity of the mist shield 4 is provided with a probe body 5, and the probe body 5 is suspended below the rotating seat 8 through its own cable, as shown in FIG. Figure 1 and Figure 8 As shown, the rotating seat 8 clamps the cable of the probe body 5, so that the probe body 5 is suspended in the inner cavity of the mist shield 4 to reduce the contact between the surface of the probe body 5 and other objects, thereby avoiding dead angles on the surface of the probe body 5 and affecting the cleaning and disinfection effects.

[0042] In order to install the mist exhaust fan 7, the present application also has a mounting groove 11 at the bottom of the base 1, a mist exhaust hole 12 is opened at the bottom of the mounting groove 11, and the mist exhaust hole 12 is connected to the inner cavity of the outer tube 2, and the mist exhaust fan 7 is rotatably installed in the inner cavity of the mounting groove 11. Figure 5 As shown, the mist exhaust fan 7 rotates to extract the air in the inner cavity of the mist shield 4, and at the same time, the water mist can be sucked into the installation groove 11. The mist exhaust fan 7 is in the shape of a truncated cone with a concave side, and the top of the mist exhaust fan 7 passes through the inner cavity of the mist exhaust hole 12, as shown in FIG. Figure 7 As shown, the surface of the mist exhaust fan 7 is provided with a plurality of arc-shaped strip plates as fan blades. Since the top of the mist exhaust fan 7 extends into the inner cavity of the mist shield 4, the mist exhaust fan 7 can stir the air in the inner cavity of the mist shield 4 into a vortex shape when rotating, so that the water mist can fully adhere to each corner of the surface of the probe body 5.

[0043] In order to filter impurities mixed with water mist, the present application also has an annular filter cartridge 14 concentric with the inner cavity of the mounting groove 11, the annular filter cartridge 14 is movably sleeved on the outer side of the exhaust fan 7, and a gap is left between the annular filter cartridge 14 and the inner side wall of the mounting groove 11, and an exhaust pipe 15 is arranged on the outer side of the base 1, and the exhaust pipe 15 is connected to the inner cavity of the mounting groove 11, such as Figure 5 and Figure 6 As shown, after the water mist enters the inner cavity of the installation groove 11, the mixed impurities can be filtered by the annular filter cartridge 14, and the water mist, air, and water droplets formed after the water mist condenses can be discharged together through the exhaust pipe 15. The open end of the installation groove 11 is fixedly connected with a cover 13 by bolts. The setting of the cover 13 is mainly used to seal the lower end opening of the installation groove 11, and is also used to support the annular filter cartridge 14 and the exhaust fan 7.

[0044] In order to drive the mist exhaust fan 7 to rotate, the present application also has a motor bin 131 formed by an upward depression in the middle of the cover 13, and a depression groove 71 compatible with the motor bin 131 is opened in the middle of the lower surface of the mist exhaust fan 7, and the motor bin 131 is located in the inner cavity of the depression groove 71 and a bearing 72 is arranged therebetween. The mist exhaust fan 7 is rotatably sleeved on the outer side of the motor bin 131 through the depression groove 71 and the bearing 72, and the mist exhaust fan 7 and the cover 13 maintain relative rotation and will not separate from each other. An annular sealing gasket 73 is arranged between the lower surface of the mist exhaust fan 7 and the upper surface of the cover 13, and the annular sealing gasket 73 is used to form a seal between the mist exhaust fan 7 and the cover 13 to prevent water mist and water droplets from entering the inner cavity of the depression groove 71, and a mist exhaust motor 132 is installed in the inner cavity of the motor bin 131, and the output shaft of the mist exhaust motor 132 passes through the bottom of the groove of the motor bin 131 and is fixedly connected to the mist exhaust fan 7, and the mist exhaust motor 132 drives the mist exhaust fan 7 to rotate.

[0045] In order to position the sealing door 3, the present application also has a reflective layer 32 on the inner walls of the outer cylinder 2 and the sealing door 3. The reflective layer 32 is used to reflect ultraviolet light and collect the ultraviolet light to irradiate on the probe body 5. A sealing layer 33 is provided at the joint between the two sealing doors 3 to ensure the sealing of the inner cavity of the outer cylinder 2. A magnet sheet 34 is fixedly provided on the top of the inner wall of the sealing door 3, and a metal sheet corresponding to and adsorbed to the magnet sheet 34 is provided at the top edge of the outer cylinder 2. The magnet sheet 34 and the metal sheet attract each other and are used to position the sealing door 3 when the sealing door 3 is closed to prevent the sealing door 3 from shaking and affecting the sealing of the inner cavity of the mist shield 4.

[0046] In order to rotate the probe body 5 in the inner cavity of the mist shield 4, the present application also has a C-shaped shell 87 fixedly installed on the top surface of the base 1, and a V-shaped groove 17 is opened at the top edge of the outer cylinder 2. The V-shaped groove 17, the notch of the C-shaped shell 87 and the notch of the mist shield 4 correspond to each other. The rotating seat 8 is rotatably installed in the middle of the C-shaped shell 87. The rotating seat 8 can only rotate in the middle of the C-shaped shell 87 without being separated from it. The cross-section of the rotating seat 8 is a "C" shape concentric with the C-shaped shell 87, such as Figure 8 and Fig. 9 As shown, the cable on the horizontally moving probe body 5 can pass through the V-groove 17, the notch of the C-shaped shell 87 and the notch of the rotating seat 8, so that the probe body 5 is placed in the inner cavity of the mist shield 4 for suspension. In addition, by rotating the rotating seat 8, the probe body 5 suspended below can also be rotated to change the irradiation range and angle of the ultraviolet light on the probe body 5, ensuring that all positions on the surface of the probe body 5 can be evenly sterilized.

[0047] In order to stably clamp the cable on the probe body 5, the rotating seat 8 of the present application is configured to have two layers, the upper and lower layers, and the middle part is fixedly connected by a vertical plate 84, such as Fig. 9As shown, the vertical plate 84 is located at the edge of the rotating seat 8, and a "C"-shaped snap ring 81 is rotatably installed in the middle of the rotating seat 8. The snap ring 81 can rotate in the middle of the rotating seat 8. When the notch of the snap ring 81 is misaligned with the notch on the rotating seat 8, the cable of the probe body 5 can be clamped and fixed by the snap ring 81 and the rotating seat 8. Flexible pads 82 are bonded to the inner walls of the notch of the rotating seat 8 and the notch of the snap ring 81, which are used to increase the friction force on the cable on the probe body 5 and prevent the probe body 5 from falling under the action of its own weight. The snap ring 81 is located above the C-shaped shell 87, and the side of the snap ring 81 is provided with friction grooves 811. When in use, the staff can rotate the snap ring 81 with their fingers without being blocked by the C-shaped shell 87.

[0048] In order to drive the rotating seat 8 to rotate, the present application also has guide grooves 83 on the upper and lower surfaces of the rotating seat 8 that are close to each other, and guide bosses 812 that are compatible with the guide grooves 83 are fixed on the upper and lower surfaces of the snap ring 81. The guide bosses 812 and the guide grooves 83 cooperate with each other to avoid the separation of the snap ring 81 and the rotating seat 8, and ensure that the snap ring 81 can rotate freely in the middle of the rotating seat 8. A driving gear 86 is installed on the outer side of the C-shaped shell 87, and the driving gear 86 is driven to rotate by the rotating motor 85. The lower side of the rotating seat 8 is provided with an external tooth groove 861 that meshes with the driving gear 86 for transmission. Fig. 9 and Figure 8 As shown, the rotating motor 85 is a forward and reverse motor known in the prior art, and its forward and reverse rotation is controlled by an external controller, which will not be elaborated here. When the rotating motor 85 is working, it drives the driving gear 86 to rotate, and then drives the rotating base 8 to rotate. When the driving gear 86 approaches the notch at the edge of the rotating base 8, the rotating motor 85 rotates in the reverse direction until it approaches the notch at the edge of the rotating base 8 again in the reverse direction, and the rotating motor 85 resumes forward rotation, and so on.

[0049] In order to prevent the water mist in the inner cavity of the mist shield 4 from leaking to the top of the outer tube 2, the present application also has an elastic rubber sheet arranged in the inner cavity of the V-shaped groove 17. In order to prevent the water mist in the inner cavity of the mist shield 4 from passing through the V-shaped groove 17 and leaking to the top of the outer tube 2, the edge of the elastic rubber sheet is bonded and fixed to the inner wall of the V-shaped groove 17, and a cutout groove for the cable of the probe body 5 to pass through is opened in the middle of the elastic rubber pad, such as Figure 8 As shown, the cable on the probe body 5 can move along the cut groove of the elastic rubber pad in the inner cavity of the V-groove 17, squeezing the elastic rubber pad during movement, and the elastic rubber pad is reset after being moved away. In addition, a window 18 is provided at the top of the outer tube 2 for the staff to observe the state of the inner cavity of the outer tube 2.

[0050] In order to allow dry air from the outside to pass into the inner cavity of the mist shield 4, the present application also has a one-way intake valve 9 installed on the top of the outer cylinder 2, and the lower end of the one-way intake valve 9 is connected to the inner cavity of the mist shield 4, an intake hole 91 is opened through the top of the one-way intake valve 9, and a sealing ball 92 is provided in the inner cavity of the one-way intake valve 9, a compression spring 94 is fixed to the lower side of the sealing ball 92, and a porous plate 95 is provided at the lower end of the compression spring 94, the porous plate 95 is fixed to the inner wall of the opening at the lower end of the one-way intake valve 9, and a circular sealing chamfer 93 that fits with the sealing ball 92 is provided at the corner of the inner wall at the top of the one-way intake valve 9, the porous plate 95 is provided for supporting the compression spring 94, and the elastic force of the compression spring 94 itself is used to push the sealing ball 92 to move upward and block the intake hole 91, and the sealing chamfer 93 is provided for In cooperation with the sealing ball 92, the sealing effect of the sealing ball 92 on the air intake hole 91 is improved. The function of the one-way air intake valve 9 is mainly reflected in: when the water mist inlet pipe 16 stops supplying water mist to the inner cavity of the mist shield 4, the valve on the water mist inlet pipe 16 can be directly closed. At this time, a negative pressure is formed in the inner cavity of the mist shield 4, and the sealing ball 92 moves downward under the action of the negative pressure and opens the air intake hole 91. At this time, the inner cavity of the mist shield 4 can directly draw dry air from the outside through the one-way air intake valve 9, thereby avoiding the inner cavity of the water mist inlet pipe 16 being too moist, resulting in the inner cavity of the mist shield 4 being unable to be dried by the air in time; and when the water mist inlet pipe 16 is opened, since the external atomization equipment will transport water mist to the inner cavity of the mist shield 4 through the water mist inlet pipe 16, the inner cavity of the mist shield 4 will not generate excessive negative pressure, and the air intake hole 91 will not be opened.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
