Referring to fig. 1 to 7, the present disclosure provides a sterilization can, which includes a can body 110, a can cover 120, a rotating disc 410 and a hook 420, wherein the can body 110 is configured with an accommodating space and an opening communicated with the accommodating space; a can cover 120 openably and closably disposed at an opening of the can body 110; the rotary table 410 is sleeved on the tank body 110 and can rotate along the circumferential direction of the tank body 110, and the rotary table 410 is provided with a guide groove 411; the hook 420 is rotatably connected to the tank body 110 through a shaft pin, a first end of the hook 420 is used for clamping the tank cover 120, a second end of the hook 420 is located in the guide groove 411, wherein when the turntable 410 rotates in the first direction, the second end of the hook 420 moves outwards in the radial direction of the tank body 110 under the guide effect of the guide groove 411, and the first end of the hook 420 is driven to move inwards in the radial direction of the tank body 110 so as to clamp the tank cover 120.

In the disclosed embodiment, the sterilization can includes a can body 110 and a can lid 120. The tank 110 is configured with an accommodating space and an opening communicating with the accommodating space, and the sterilization object is placed into the accommodating space through the opening. The cover 120 is used to cover the opening of the receiving space. The sterilization jar is under the user state, and uncovered can be opening at the top, also can open at the side, for the convenience of description, in the embodiment of disclosing to the vertical setting of sterilization jar and uncovered opening are introduced for the example at the top. The turntable 410 is annular, is sleeved on the tank 110, and can rotate around the axis of the tank 110. The snap 420 is used to secure the can lid 120. When the sterilization is performed in a working state, the inside of the can is in a high-temperature and high-pressure environment, and the hook 420 clamps the can cover 120 to prevent the high-temperature and high-pressure gas inside the can body 110 from ejecting the can cover 120. The rotating shaft of the hook 420 is disposed on the can body 110, and the axis of the rotating shaft is located on the horizontal plane and parallel to the tangent line of the can body 110 at the rotating shaft. The rotating shaft penetrates through the middle part of the clamping hook 420 to form a lever structure, and the rotating shaft is a fulcrum of the lever. The first end of the hook 420 is located at the top end to stop the can lid 120 covering the open end. Specifically, in the locked state of the hook 420, the end of the first end of the hook 420 is caught on the upper surface of the can cover 120, thereby limiting the movement of the can cover 120 in the vertical direction. By moving the second end of the hook 420, the hook 420 rotates around the rotation axis, thereby switching between the locked state and the unlocked state. The turntable 410 is opened with a guide slot 411, and the guide slot 411 is used for guiding the movement of the first end of the hook 420. Specifically, the guide slot 411 converts the rotation of the rotary table 410 in the horizontal plane into the swing of the hook 420 in the vertical plane, thereby driving the hook 420 to lock the can cover 120 or to contact-lock the can cover 120.

By using the sterilization tank provided by the embodiment of the disclosure, the rotating disc 410 rotates to drive the hook 420 to rotate, so that the tank cover 120 is locked or unlocked, and the sterilization tank is convenient to operate and easy to use. When the can cover 120 is locked or unlocked, the rotation torque of the rotary disc 410 is converted into the swing torque of the clamping hook 420, the force arm is normal, the force is reduced, and the operation is easy and labor-saving. The clamping cover 120 is not easy to deform due to the pulling force along the length direction of the clamping hook 420, the rotating shaft of the clamping hook 420 is perpendicular to the axis of the tank body 110, and the rotating shaft is even in stress and not easy to bend.

Optionally, the distance between the guide slot 411 and the can body 110 gradually increases from the first end to the second end of the guide slot 411, when the rotary table 410 rotates towards the first direction, the second end of the guide slot 411 moves towards the first direction, and the second end of the hook 420 rotates under the driving of the guide slot to move radially outwards along the can body 110 where the hook 420 is located, until the second end of the hook 420 moves to the second end of the guide slot. When the second end of the hook 420 is located at the first end of the guide groove, the distance from the first end of the hook 420 to the center of the can cover 120 is less than the radius of the can cover 120, so as to clamp the can cover 120. When the second end of the hook 420 is located at the first end of the guide groove, the distance from the first end of the hook 420 to the center of the can cover 120 is greater than the radius of the can cover 120, so that the can cover can be opened normally.

Alternatively, the guide slot 411 may gradually decrease in the rate of increasing distance from the can 110 from the first end to the second end thereof.

When the turntable 410 rotates in the first direction, in the first stage, the first end of the hook 420 moves from outside to inside until contacting with the can cover 120, and only the hook 420 needs to be driven to rotate in the process, so that the load of the turntable 410 is small, and when the turntable 410 rotates at a constant angular speed, the rotation speed of the hook 420 is fast, and the rotation angle is large. Therefore, the moving speed of the hook 420 can be increased, and the time required by locking can be shortened. In the second stage, after the hook 420 contacts the can lid 120, the turntable 410 not only drives the hook 420 to rotate, but also needs to drive the hook 420 to press the can lid 120, and the rotation load is larger. When the turntable 410 rotates at a constant angular speed, the hook 420 rotates at a slower speed, the rotation angle is smaller, the force arm is unchanged, and the pressure of the first end of the hook 420 on the can lid 120 is increased. The turntable 410 rotates at a constant speed and a constant torque, and the force of the hook 420 on the can lid 120 is increased during the second stage, so that the can lid 120 can be pressed against the opening of the can body 110. This arrangement can smooth the process of locking the can lid 120 by rotating the turntable 410.

Alternatively, the guide slot 411 has an arc shape protruding to the outside of the can 110.

Thus, when the turntable 410 rotates at a constant speed, the rotation speed of the hook 420 gradually decreases. When the second end of the hook 420 approaches the second end of the guide slot 411, the force applied to the can cover 120 by the first end of the hook 420 is increased without changing the force for driving the rotation of the turntable 410, so that the can cover 120 can be locked better. This expression is used to describe another alternative embodiment. Through the arrangement mode, the process that the rotary table 410 locks the tank cover 120 is smoother, and meanwhile, the clamping hook 420 presses the tank cover 120 better, so that the sealing effect of the sterilization tank is improved.

The turntable 410 is provided with a guide slot 411, and the distance from the first end to the second end of the guide slot 411 to the tank 110 is gradually increased. The rotation axis of the hook 420 passes through the hook 420, so the hook 420 can only rotate in the radial vertical plane of the tank where the hook 420 is located. The second end of the hook 420 is located in the guide slot 411. When the hook 420 rotates in the first direction, the guide slot 411 rotates, so that the second end of the hook 420 slides in the guide slot 411. The second end of the hook 420 slides from the first end of the guide slot 411 to the second end of the guide slot 411, and is spaced apart from the can 110 by a gradually increasing distance, i.e., moves outward. When the second end of the hook 420 moves outwards, the first end of the hook 420 is driven to move inwards to be clamped on the upper surface of the tank cover 120, so that the tank cover 120 is locked. When the hook 420 rotates in the second direction, the guide slot 411 slides relative to the second end of the hook 420, and the hook 420 slides from the second end of the guide slot 411 to the first end of the guide slot 411, so that the distance from the tank 110 is gradually reduced, i.e., moves inward. The second end of the hook 420 is moved inward to drive the first end of the hook 420 to move outward, thereby moving away from the upper surface of the can lid 120 and releasing the locking of the can lid 120.

Alternatively, the can lid 120 is hinged to the can body 110 by a hinge, and the hook 420 is disposed opposite to the hinge.

With this arrangement, when the can lid 120 is closed, the can lid 120 can be effectively locked by using the hook 420. In addition, the hinged connection of the can lid 120 to the can body 110 facilitates the opening and closing of the can lid 120.

Alternatively, when the second end of the hook 420 is located at the second end of the guide slot 411, the hook 420 is parallel to the axis of the can 110.

When the second end of the hook 420 is located at the second end of the guide slot 411, the first end of the hook 420 is connected to the upper surface of the sterilization tank, so as to lock the sterilization tank. When the internal pressure of the sterilization can rises, there is a force to lift the can lid 120 upward. The hook 420 is parallel to the axis of the can 110, and the acting force is mainly expressed as a pulling force of the hook 420 along the length direction of the hook 420, and a small part of the pulling force is converted into a force pushing the second end of the hook 420 outwards. This force can be easily counteracted by the fixation of the dial 410 to the second end of the hook 420. In such a configuration, the reaction force of the can cover 120 to the hook 420 is mainly represented as a pulling force to the hook 420 itself, so that the hook 420 is more reasonably stressed, the structural strength of the sterilization can is improved, and the sealing effect of the sterilization can is further improved.

Optionally, the sterilization tank includes a plurality of hooks 420, the plurality of hooks 420 are disposed at intervals along the circumferential direction of the tank body 110, the turntable 410 is provided with a plurality of guide slots 411, and second ends of the plurality of hooks 420 are located in the plurality of guide slots 411 in a one-to-one correspondence manner.

The rotary plate 410 is provided with a plurality of guide slots 411 corresponding to the plurality of hooks 420, and when the rotary plate 410 rotates, the first ends of the plurality of hooks 420 synchronously move inwards or outwards to lock and unlock the tank cover 120. With this arrangement, the plurality of hooks 420 can uniformly lock the can lid 120 from a plurality of angles, thereby better locking the can lid 120. The plurality of hooks 420 are spaced apart to facilitate sealing between the can lid 120 and the can body 110.

Optionally, the number of the hooks 420 is 4, and the 4 hooks 420 are uniformly arranged.

If the number of the hooks 420 is large, the hooks 420 which need to be driven when the can cover 120 is locked are large, the rotation resistance of the rotary table 410 is large, and the use is laborious. The 4 hooks 420 can ensure the locking effect of the can cover 120 and reduce the rotation resistance of the turntable 410.

Optionally, the surfaces of the can lid 120 and the can lid 120 that contact are provided with a sealing ring.

The sealing ring may be disposed on the cover 120 or on the opening of the can body 110, and when the cover 120 covers the opening of the cover 120, the sealing ring is disposed between the cover 120 and the can body 110. The sealing effect of the sterilization tank can be improved by arranging the sealing ring.

Optionally, the sterilization pot further comprises a turntable assembly 430, and the turntable assembly 430 comprises a base 431, an upper rolling wheel 432 and a lower rolling wheel 433, wherein the base 431 is fixed on the outer wall of the pot body 110; an upper rolling wheel 432 rotatably disposed on the base 431, the rotating shaft being disposed along a radial direction of the can body 110, and the outer ring being in rolling contact with the upper surface of the turntable 410; and the lower rolling wheel 433 is rotatably arranged on the base 431, the rotating shaft is arranged along the radial direction of the tank body 110, the outer ring is in rolling contact with the lower surface of the turntable 410, and the lower rolling wheel 433 and the upper rolling wheel 432 limit the movement of the turntable 410 along the axial direction of the tank body 110.

lower rollers

432 and 433 are respectively rolled and pressed against the upper and lower surfaces of the turntable 410, and on the one hand, restrict the movement of the turntable 410 in the vertical direction, so that the movement of the turntable 410 occurs in the horizontal plane. On the other hand, the upper roller wheels 432 and the lower roller wheels 433 can reduce the friction force of the rotation of the turntable 410, so that the turntable 410 can be rotated in a horizontal plane with less effort.

Optionally, the turntable assembly portion 430 further includes: and the side rolling wheel 434 is rotatably arranged on the base 431, the rotating shaft is arranged along the axial direction of the tank 110, the outer ring is in rolling contact with the surface of the outer ring of the turntable 410, and the side rolling wheel 434 limits the movement of the turntable 410 along the radial direction of the tank 110.

The side scroll wheels 434 laterally support the turntable 410 and stop the turntable 410 from translating in a horizontal plane, thereby allowing the turntable 410 to rotate only in the horizontal plane. The side rolling wheels 434 are provided to improve the fixing effect of the turntable assembly 430 to the turntable 410.

Alternatively, the turntable assembly portion 430 is provided in plurality, and the plurality of turntable assembly portions 430 are spaced apart along the circumference of the can 110 to provide a rotation track for the turntable 410.

Optionally, the sterilization tank further includes a pressure lock 200 attached to an outer wall of the tank body 110, the pressure lock 200 includes: the first telescopic lock pin 230 is arranged along the axial direction of the tank body 110, the rotary table 410 is provided with a first lock hole 412, and when the second end of the hook 420 moves to the second end of the guide groove 411, the first telescopic lock pin 230 corresponds to the first lock hole 412; and a driving part for driving the first telescopic latch 230 to extend into the first latch hole 412 when the pressure inside the can 110 exceeds a preset value.

If the pressure inside the can body 110 is higher than the pressure inside the can body, if the contact hook 420 locks the can cover 120, the can cover 120 will bounce, and the high-temperature gas will be sprayed out, which will cause a great threat to the safety of the operator. The pressure lock 200 is arranged, the rotary disc 410 is locked by the pressure lock 200 under the condition that the pressure in the tank is higher than the preset value, and the tank cover 120 cannot be opened, so that the use safety of the sterilization tank is improved.

Optionally, the driving part includes a piston cylinder 210, a first retractable locking pin 230 and an air pipe 220, wherein the piston cylinder 210 is fixed on the outer wall of the tank 110, and the piston cylinder 210 is provided with a piston hole; the first telescopic locking pin 230 is slidably connected to the piston hole, a first end of the first telescopic locking pin is located in the piston cylinder 210, a second end of the first telescopic locking pin is located outside the piston cylinder 210, and when the pressure in the piston cylinder 210 rises, the first telescopic locking pin 230 slides outwards under the action of the pressure difference between the inside and the outside of the piston cylinder 210; the air tube 220 has a first end extending to the accommodating space and a second end communicating with the piston cylinder 210, so as to transmit the pressure of the accommodating space into the piston cylinder 210.

The first end of the air tube 220 extends to the accommodating space, so that the pressure of the accommodating space can be transmitted to the first space. When the pressure in the accommodating space rises, the pressure in the piston cylinder 210 rises, so that the first retractable locking pin 230 extends out. Specifically, the first end of the first retractable locking pin 230 is pressurized by the piston 210, and the pressurized forces in the other directions are balanced by forces in opposite directions, except for a force directed axially outward along the first retractable locking pin 230. The second end of the first retractable locking pin 230 is subject to atmospheric pressure, and the pressures in the other directions are balanced by forces in opposite directions, except for a force directed axially inward along the first retractable locking pin 230. As the pressure in the barrel 210 increases, the first retractable locking pin 230 is forced outwardly to move outwardly, i.e., extend out of the barrel 210, in excess of the inward force. By adopting the arrangement mode, the pressure lock 200 is driven by the pressure in the tank body 110, the automatic locking of the pressure lock 200 can be realized without arranging an additional pressure detection device and a driving device, the structure is simple, the function is reliable, and the cost is lower.

Optionally, the first end of the air tube 220 is communicated with the accommodating space.

Thus, the pressure in the accommodating space can be effectively transmitted to the first space of the piston through the air pipe 220, so that the pressure lock 200 can achieve its self-locking function.

Optionally, the pressure lock 200 further includes a pressure air bag disposed in the accommodating space and communicated with the second end of the air tube 220.

The pressure air bag is filled with normal pressure air. When the pressure inside the can 110 rises, the pressure bladder is compressed, thereby compressing the air in the air tube 220, and further transmitting the pressure of the accommodating space to the first space of the piston. The pressure air bag is arranged, so that pressure transmission is realized, and meanwhile, water and water vapor in the accommodating space can be prevented from entering the air pipe 220 and entering the piston. The pressure airbag realizes the transmission of pressure, and separates the direct communication between the piston and the accommodating space, and even if the sealing performance of the cylinder is reduced or the air pipe 220 is broken, the air in the accommodating space cannot be leaked. This also improves the reliability of the use of the sterilization pot.

Optionally, the pressure lock 200 further comprises a first return spring, both ends of the first return spring are respectively connected to the piston cylinder 210 and the first retractable locking pin 230, and the return spring makes the first retractable locking pin 230 in a retracted state in an initial state.

When the pressure inside the can body 110 rises, the pressure difference between the first space and the second space of the piston causes the piston to act against the elastic force of the first return spring, thereby extending the first retractable locking pin 230 to complete the locking of the can lid 120. When the pressure inside the can 110 is reduced, the first return spring returns the first retractable locking pin 230, so that the pressure lock 200 performs an unlocking operation. The pressure lock 200 can be automatically unlocked by arranging the first return spring.

Alternatively, the piston cylinder 210 is vertically disposed, and the second space is located at an upper portion of the first space.

When the pressure inside the can body 110 rises, the pressure difference between the first space and the second space of the piston causes the piston to move upward against its own weight, thereby extending the first retractable locking pin 230 to complete the locking of the can lid 120. When the pressure inside the can body 110 is reduced, the piston moves downward by its own weight, thereby retracting the first retractable locking pin 230 to complete the unlocking of the can lid 120. With this arrangement, the pressure lock 200 can be automatically unlocked.

Optionally, the sterilization tank further includes an electromagnetic lock 300 attached to the outer wall of the tank body 110, the electromagnetic lock 300 includes a second retractable lock pin and a second return spring, wherein the second retractable lock pin is arranged along the axial direction of the tank body 110, the turntable 410 is provided with a second lock hole 413, and when the second end of the hook 420 moves to the second end of the guide groove 411, the second lock hole 413 corresponds to the second retractable lock pin; and the second return spring is elastically connected to the second telescopic lock pin, and when the second locking hole 413 corresponds to the second telescopic lock pin in position, the second telescopic lock pin extends into the second locking hole 413 under the elastic force of the second return spring.

The locking of the can cover 120 can be realized by the locking turntable 410 by using the arrangement form that the turntable 410 drives the hook 420 to clamp the can cover 120. And the moment arm of the turntable 410 is relatively long, less force is required to lock the turntable 410 and thereby prevent the can lid 120 from being opened. The turntable 410 is sleeved on the tank body 110, the electromagnetic lock 300 is arranged on the outer wall of the tank body 110, and the second telescopic lock pin is vertically arranged. When the second end of the hook 420 moves from the first end of the guide slot 411 to the second end of the guide slot 411, the second retractable lock pin elastically contacts and presses the surface of the rotary disc 410 under the action of the second return spring, when the second end of the hook 420 moves to the second end of the guide slot 411, the second locking hole 413 corresponds to the second retractable lock pin, and the second retractable lock pin extends into the second locking hole 413, so that the cover 120 is locked.

Optionally, the electromagnetic lock 300 comprises a coil that surrounds the second retractable locking pin to form an electromagnet, the second retractable locking pin retracting under the attraction of the electromagnet when the coil is energized.

Thus, the electromagnetic lock 300 retracts the second retractable locking pin when energized, and the electromagnetic lock 300 extends the second retractable locking pin when de-energized. The coil of the electromagnetic lock 300 includes a control circuit that opens in the event that the temperature is above a preset value. This facilitates control of the electromagnetic lock 300.

Optionally, the sterilization tank further comprises a control part configured to prohibit the electromagnetic lock 300 from being unlocked if the temperature of the accommodating space is greater than a preset temperature.

The sterilization tank is in a working state, and the inside of the sterilization tank is in a high-temperature and high-pressure environment. If the can cover is opened under high pressure, the high-temperature gas is ejected by the bouncing of the can cover, and a user is in danger of being burned by mechanical impact or the high-temperature gas. If the pressure in the tank body is lower and the inside of the tank body is in a high-temperature environment, a user still has the danger of being scalded when opening the tank cover to take and place the sterilization object. The control part can make the electromagnetic lock and the temperature inside the tank body perform interlocking action. Through setting up pressure lock and mechanical lock, the pressure lock links with the pressure of the internal portion of jar, and electromagnetic lock links with the temperature of the internal portion of jar. The user can only open the cover under the condition that the temperature and the pressure in the tank are lower than the preset values, so that the safety of the user is guaranteed, and the use safety of the sterilization tank is improved.
