Description

Technical Field

[0001] This utility model belongs to the field of vacuum box-type medicine moistening machine, and relates to a snap-fit ​​fixing structure for a vacuum box-type medicine moistening machine. Background Technology

[0002] Vacuum box-type herbal moistening machines can quickly moisten dry medicinal materials in a low-pressure, high-temperature, and high-steam environment, creating conditions for subsequent processing of the medicinal materials.

[0003] To facilitate the drainage of condensate from the vacuum chamber-type dehumidifier, the internal base plate slopes downwards from the inside out. However, during use, when the herb storage box (equipped with wheels for easy transport) is placed inside the vacuum chamber, it tends to slide downwards on its own. This is extremely inconvenient for single-person operation, requiring the use of other materials, such as bricks, to place in front of the wheels. Furthermore, there is a risk of accidental sliding, with the storage box potentially sliding out of the machine and impacting a person or the equipment. Additionally, both the sliding downwards of the storage box and the use of bricks interfere with the closing of the vacuum chamber's door. Utility Model Content

[0004] To overcome the deficiencies in the aforementioned related technologies, this utility model proposes a snap-locking structure for a vacuum box-type medicine moistening machine, which facilitates operators in locking the medicine storage box inside the vacuum box-type medicine moistening machine.

[0005] To achieve the above technical objectives, this utility model provides a snap-fit ​​fixing structure for a vacuum box-type herbal moistening machine. The snap-fit ​​fixing structure includes: a box body, rails, and snap fasteners. The box body has an opening on one side and includes a bottom plate that slopes upwards from the opening. The rails include two straight rails fixed to the bottom plate, extending inwards from the opening. Each rail has a snap fastener fixed to one side, and the line connecting the center points of two snap fasteners is perpendicular to the rail. The snap fasteners are configured to lock or release the herbal storage cart when it is pressed down.

[0006] The latch includes a housing, a first switch, a locking element, and a second switch. The housing is fixedly connected to the track, and the first switch, locking element, and second switch are sequentially installed inside the housing from the opening inwards. When the upper surface of the first switch is pressed down to be flush with the upper surface of the track, the first switch activates the circuit. When the upper surface of the second switch is pressed down to be flush with the upper surface of the track, the second switch activates the circuit. After the first switch is pressed down, the locking element moves downwards and becomes flush with the upper surface of the track. After the second switch is pressed down, the locking element moves upwards. After the second switch remains pressed down for a time period t and is opened and closed at least once in a subsequent time period S, the locking element becomes flush with the upper surface of the track.

[0007] Preferably, the buckle further includes a sealing plate, which is a plate adapted to the internal shape of the housing. The sealing plate is horizontally disposed inside the housing, and the sealing plate is waterproofed to the side wall of the housing.

[0008] Preferably, the first switch further includes: a first pressing button, a first return spring, and a first magnetic proximity switch. The first pressing button is movably disposed on the top wall of the housing, and its lower end is a permanent magnet. The first return spring is disposed between the first pressing button and the sealing plate. The first magnetic proximity switch is disposed below the sealing plate, and is activated when the first pressing button approaches the sealing plate.

[0009] Preferably, the second switch further includes: a second press-down button, a second return spring, and a second magnetic proximity switch. The second press-down button is movably disposed on the top wall of the housing, and its lower end is a permanent magnet. The second return spring is disposed between the second press-down button and the sealing plate. The second magnetic proximity switch is disposed below the sealing plate, and is activated when the second press-down button approaches the sealing plate.

[0010] Preferably, the locking mechanism includes: a battery, an intermediate relay, an electromagnet, a spindle, a support plate, and a limiting ear. The battery is disposed within a housing below the enclosed plate. The intermediate relay is disposed within the housing below the enclosed plate, and its first contact is electrically connected to the positive terminal of the battery. The electromagnet is disposed within a housing above the enclosed plate, with one end of its coil electrically connected to the second contact of the intermediate relay and the other end of its coil electrically connected to the negative terminal of the battery. The spindle is horizontally mounted on both side walls of the housing, and a torque spring is fitted onto the spindle, with one end of the torque spring also fixed to the support plate. The support plate is fixed to the spindle. The limiting ear is fixed to the housing. The limiting ear is configured to limit the height at which the torque spring lifts the support plate upwards. When the support plate abuts against the limiting ear and the wheel of the medicinal material storage vehicle abuts against the support plate, the angle between the connection between the center point of the wheel of the medicinal material storage vehicle and the center line of the main shaft and the horizontal plane is smaller than the angle between the connection between the contact point between the wheel and the support member and the center line of the main shaft of the medicinal material storage vehicle and the horizontal plane.

[0011] Preferably, the snap-fit ​​fixing structure of the vacuum box-type medicine moistening machine further includes a microprocessor. The microprocessor is electrically connected to the first magnetic proximity switch, the second magnetic proximity switch, and the intermediate relay, and the battery also powers the microprocessor.

[0012] Drainage holes are provided on the outer casing sidewall above the sealing plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model features a track that allows the medicinal herb storage box to be positioned relatively within the box, making it easy for the wheels of the medicinal herb storage box to touch the first switch, the locking mechanism, and the second switch. This eliminates the need for deliberate operation by the operator, thus offering the advantages of being simple and convenient to use without requiring the operator's attention.

[0015] After the first switch of this utility model is pressed down, it can ensure that the upper end of the card is flush with the upper surface of the track, preventing the card from interfering with the entry of the medicine storage box.

[0016] This utility model uses a support plate to prevent the medicinal material storage box from sliding out, making it convenient for a single operator to work and to facilitate the closing of the vacuum box-type medicine moistening machine's sealing door. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0024] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] like Figures 1 to 4As shown, some embodiments of this utility model provide a snap-fit ​​type 3 fixing structure for a vacuum box-type medicine moistening machine. The snap-fit ​​type 3 fixing structure of the vacuum box-type medicine moistening machine includes: a box body 1, a track 2, and snap-fit ​​3. The box body 1 has an opening on one side and includes a bottom plate that slopes upwards from the opening. The track 2 includes two straight rails fixed to the bottom plate, extending inwards from the opening. Each side of each track 2 is fixed with a snap-fit ​​3, and the line connecting the center points of two snap-fit ​​3s is perpendicular to the track 2. The snap-fit ​​3 is configured to lock or release the medicine storage cart when it is pressed down.

[0026] The latch 3 includes a housing 31, a first switch 32, a latch 33, and a second switch 34. The housing 31 is fixedly connected to the track 2, and the first switch 32, latch 33, and second switch 34 are sequentially installed inside the housing 31 from the opening inwards. When the upper surface of the first switch 32 is pressed down to be flush with the upper surface of the track 2, the first switch 32 conducts the circuit. When the upper surface of the second switch 34 is pressed down to be flush with the upper surface of the track 2, the second switch 34 conducts the circuit. After the first switch 32 is pressed down, the latch 33 moves downwards and becomes flush with the upper surface of the track 2. After the second switch 34 is pressed down, the latch 33 moves upwards. After the second switch 34 remains pressed down for a time period t and is opened and closed at least once in a subsequent time period S, the latch 33 becomes flush with the upper surface of the track 2.

[0027] In some examples, the opening of the box 1 is equipped with a closed door. Two straight rails are fixed on the bottom plate of the box 1. The two straight rails are arranged in parallel and close to the two side walls of the box 1 respectively. The front end of the straight rails extends to the opening of the box 1, and the upper surface of the straight rails should be flush with the plane of the opening of the box 1 to facilitate the entry and exit of the medicine storage box.

[0028] A latch 3 is installed on the outside of the two straight rails and near the door of the box 1. This can prevent the latch 3 from affecting the medicine stored inside the medicine storage box, and also make it convenient for operators to inspect and maintain the latch 3 at the door of the box 1.

[0029] During operation, the latch 3 can contact the wheels of the herbal medicine storage box. Specifically, when the herbal medicine storage box enters the box body 1, the wheels of the herbal medicine storage box first press down the first switch 32. When the circuit of the first switch 32 is turned on, the latch 33 is controlled to press down to be horizontal with the upper surface of the track 2, so the wheels can pass through the latch 33. When the wheels of the herbal medicine storage box press down the second switch 34, the latch 33 is controlled to rise and protrude from the upper surface of the track 2 to prevent the herbal medicine storage box from sliding out of the box body 1.

[0030] It should be noted that when the second switch 34 is close to the locking piece 33, the medicine storage box inside the box 1 will abut against the locking piece 33, and at the same time, the wheels of the medicine storage box will continuously press down on the second switch 34. When it is necessary for the medicine storage box to exit the box 1, the medicine storage box can be pushed inward to raise the second switch 34, and then the medicine storage box can be pushed outward. If the second switch 34 has at least one opening and closing action within a certain period of time after being pressed down for a long time, the locking piece 33 can be controlled to move downward to allow the medicine storage box to exit the box 1 smoothly.

[0031] The second switch 34 can be pressed down for more than 30 seconds. That is to say, after the medicine storage box is pushed into the box 1, it can be pushed out of the box 1 after 30 seconds. At the same time, when it needs to be pushed out, the medicine storage box can be pushed down repeatedly. Therefore, the time interval between the wheels of the medicine storage box pressing down the second switch 34 must be less than 30 seconds, so that the jamming part 33 will not be mistakenly lowered.

[0032] For example, time t can be 30 seconds, and time S can be 10 seconds. After the medicine storage box presses down on the second switch 34 and holds it for 30 seconds, the operator pushes the medicine storage box repeatedly, causing the second switch 34 to complete three opening and closing operations within 10 seconds. At this time, the locking piece 33 can be controlled to move downwards, facilitating the exit of the medicine storage box. It should be noted that when the medicine storage box exits, the wheels located inside the box body 1 need to pass over the locking piece 33 within 10 seconds.

[0033] In some embodiments, the buckle 3 further includes a sealing plate 35, which is a plate adapted to the internal shape of the housing 31. The sealing plate 35 is horizontally disposed inside the housing 31, and the sealing plate 35 is waterproofed to the side wall of the housing 31.

[0034] This utility model is installed inside a vacuum box-type medicine moistening machine. In order to prevent steam inside the vacuum box-type medicine moistening machine from entering the interior of the outer shell 31 and causing a short circuit, a sealing plate 35 is installed inside the outer shell 31. Devices that may pose a short circuit risk can be placed inside the outer shell 31 below the sealing plate 35. The periphery of the sealing plate 35 can be sealed with waterproof adhesive strips or the like.

[0035] In some embodiments, the first switch 32 further includes: a first press-down button 321, a first return spring 322, and a first magnetic proximity switch 323. The first press-down button 321 is movably disposed on the top wall of the housing 31, and its lower end is a permanent magnet. The first return spring 322 is disposed between the first press-down button 321 and the enclosed plate 35. The first magnetic proximity switch 323 is disposed below the enclosed plate 35, and is activated when the first press-down button 321 approaches the enclosed plate 35.

[0036] The second switch 34 further includes: a second press-down button, a second return spring, and a second magnetic proximity switch. The second press-down button is movably disposed on the top wall of the housing 31, and its lower end is a permanent magnet. The second return spring is disposed between the second press-down button and the enclosed plate 35. The second magnetic proximity switch is disposed below the enclosed plate 35, and is activated when the second press-down button approaches the enclosed plate 35.

[0037] In some examples, the upper end of the enclosure plate 35 is provided with two through holes. The sensing surface of the first magnetic proximity switch 323 is provided in one through hole, and the sensing surface of the second magnetic proximity switch is provided in the other through hole. The first magnetic proximity switch 323 and the second magnetic proximity switch are filled with resin around the through holes to achieve waterproofing.

[0038] The first press button 321 is movably disposed in the through hole on the top wall of the outer casing 31. The first press button 321 is a cylindrical body with an annular part at the bottom. The annular part is coaxially and fixedly connected to the main body. The annular part can prevent the first press button 321 from falling off the top wall of the outer casing 31. A permanent magnet is also fixed at the lower end of the first press button 321.

[0039] A reset spring is fitted around the outside of the permanent magnet, with its upper end fixedly connected to the lower end of the column and its lower end fixed to the sensing surface of the first magnetic proximity switch 323. When the first press button 321 is pressed down until its upper surface is flush with the upper surface of the housing 31, the permanent magnet comes into contact with the sensing surface of the first magnetic proximity switch 323, at which point the first magnetic proximity switch 323 is turned on.

[0040] The structure of the second switch 34 is the same as that of the first switch 32, except that the position of the second switch 34 is different from that of the first switch 32. The structure of the second switch 34 will not be described in detail here.

[0041] In some embodiments, the locking component 33 includes: a battery 331, an intermediate relay 332, an electromagnet 333, a spindle 334, a support plate 335, and a limiting ear 336. The battery 331 is disposed within the housing 1 below the enclosed plate 35. The intermediate relay 332 is disposed within the housing 1 below the enclosed plate 35, and its first contact is electrically connected to the positive terminal of the battery 331. The electromagnet 333 is disposed within the housing 1 above the enclosed plate 35, with one end of its coil electrically connected to the second contact of the intermediate relay 332, and the other end of its coil electrically connected to the negative terminal of the battery 331. The spindle 334 is horizontally disposed on both side walls of the housing 1, and a torque spring is fitted onto the spindle 334, with one end of the torque spring also fixed to the support plate 335. The support plate 335 is fixed to the spindle 334. The limiting ear 336 is fixed to the housing 1. The limiting ear 336 is configured to limit the height at which the torque spring lifts the support plate 335 upward. When the support plate 335 abuts against the limiting ear 336 and the wheel of the medicinal material storage vehicle abuts against the support plate 335, the angle between the connection between the center point of the wheel of the medicinal material storage vehicle and the center line of the main shaft 334 and the horizontal plane is smaller than the angle between the connection between the contact point between the wheel and the support member and the center line of the main shaft 334 and the horizontal plane.

[0042] In some examples, a connecting plate is also provided between the main shaft 334 and the support plate 335. A torque spring is mounted on the main shaft 334, with one end of the torque spring fixed to the main shaft 334 and the other end fixed to the connecting plate. Through the torque spring, the support plate 335 can be lifted autonomously to the upper surface of the protruding outer shell 31, ensuring that the medicine storage box is locked by the support plate 335 when the box 1 is closed.

[0043] The limiting ear 336 can limit the lifting angle of the connecting plate. That is, after the support plate 335 is lifted to a certain angle, it is blocked by the limiting ear 336 and cannot be lifted further. When the support plate 335 abuts against the limiting ear 336, and the wheel of the medicinal material storage vehicle abuts against the support plate 335, the angle between the connection between the center point of the wheel of the medicinal material storage vehicle and the center line of the main shaft 334 and the horizontal plane is less than the angle between the connection between the contact point of the wheel and the support member and the center line of the main shaft 334 and the horizontal plane. At this time, the wheel of the medicinal material storage vehicle abuts against the support plate 335. At this time, the support plate 335 is subjected to pressure in the direction of approaching the limiting ear 336. In this way, the support plate 335 can prevent the medicinal material storage vehicle from sliding outward.

[0044] Electromagnet 333 is installed inside housing 31 directly below connecting plate and support plate 335. When the medicine storage cart is pushed back and forth and the second pressing button is pressed down, electromagnet 333 keeps the circuit connected and the wheels of the medicine storage cart are disengaged from support plate 335. At this time, electromagnet 333 can attract support plate 335 downward so that the medicine storage cart can pass through and exit smoothly.

[0045] In some embodiments, the snap-fit ​​fixing structure of the vacuum box-type medicine moistening machine further includes a microprocessor. The microprocessor is electrically connected to the first magnetic proximity switch 323, the second magnetic proximity switch, and the intermediate relay 332, and the battery 331 also powers the microprocessor.

[0046] The microprocessor can be a single-chip microcomputer. It is electrically connected to the first magnetic proximity switch 323, the second magnetic proximity switch, and the intermediate relay 332, respectively. After receiving the signal from the first magnetic proximity switch 323, the microprocessor sends a closing signal to the intermediate relay 332, thus activating the circuit of the electromagnet 333.

[0047] When the second magnetic proximity switch continuously sends a high-level signal to the microprocessor (the second press button is continuously pressed), and after the second magnetic proximity switch sends at least one low-level signal and at least one high-level signal to the microprocessor within a short period of time (the second press button is pressed once after being released), the microprocessor sends a closing signal to the intermediate relay 332, and the circuit of the electromagnet 333 is turned on.

[0048] After the second magnetic proximity switch stops sending a high-level signal to the microprocessor and sends a high-level signal only to the second magnetic proximity switch, the microprocessor sends a disconnect signal to the intermediate relay 332, and the circuit of the electromagnet 333 is disconnected.

[0049] Drainage holes are provided on the outer casing sidewall above the sealing plate.

[0050] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0051] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
