Description

Technical Field

[0001] This utility model relates to the field of vertical disinfection cabinet technology, and specifically to an improved vertical disinfection cabinet. Background Technology

[0002] Most existing vertical disinfection cabinets consist of an upper chamber and a lower chamber. The upper chamber uses a heating element for drying and cleaning, while the lower chamber uses another heating element for high-temperature disinfection. However, vertical disinfection cabinets only have a door control switch for the lower chamber. This means that even when the upper chamber door is open, the heating element in the upper chamber continues to operate, potentially causing excessively high temperatures in the upper chamber's inner liner or at the heating element, which could result in burns to the user. This situation warrants improvement. Utility Model Content

[0003] The purpose of this invention is to provide an improved vertical disinfection cabinet that is safe to use.

[0004] The purpose of this utility model is achieved as follows.

[0005] An improved vertical disinfection cabinet includes a cabinet body, a first cabinet door, and a second cabinet door. The cabinet body contains an independent first chamber and a second chamber, separated by a partition. The first and second cabinet doors are pivotally connected to the cabinet body. The second cabinet door seals the second chamber. A first heating element is located in the first chamber, and a second heating element is located in the second chamber. A normally open first door control switch is located on the partition corresponding to the first cabinet door. The first door control switch and the first heating element are connected in series. When the first cabinet door closes and seals the first chamber, the first door control switch is closed and energized. Similarly, a normally open second door control switch is located on the partition corresponding to the second cabinet door. The second door control switch and the second heating element are connected in series. When the second cabinet door closes and seals the second chamber, the second door control switch is closed and energized.

[0006] Furthermore, the partition is provided with mounting holes and mounting cavities for the first and second door switches respectively. The mounting cavities are connected to the outside through the mounting holes. At least one positioning notch is provided on the side of the mounting hole. The first and second door switches are provided with locking protrusions on their outer sides. When the first and second door switches are inserted into the corresponding mounting holes, the locking protrusions rotate in the mounting cavities after passing through the positioning notches. The locking protrusions and positioning notches are misaligned to prevent the first and second door switches from disengaging from the corresponding mounting holes.

[0007] The door control switch is simple and easy to install, and convenient to disassemble and maintain.

[0008] Furthermore, the outer end of the partition corresponding to the mounting hole is provided with an annular protrusion, the front of the annular protrusion is lower than the front of the partition, and the positioning notch communicating with the mounting hole is provided on the annular protrusion.

[0009] The annular protrusion prevents the locking protrusion inside the mounting hole from disengaging from the mounting hole, ensuring the door switch is securely installed.

[0010] Furthermore, the first door control switch and the second door control switch have the same structure and both include a front end cover and a sleeve. The front end cover is sealed and fixed to the front end of the sleeve. The sleeve has a locking protrusion on its outer periphery, and a gap is left between the front end cover and the locking protrusion to hold the annular protrusion.

[0011] The door switch is inserted to a reasonable depth, making it difficult for it to enter the installation cavity.

[0012] Furthermore, both the first and second door control switches also include a micro switch, a spring, and a contact rod. The micro switch is located at the bottom of the sleeve, and has a terminal at the rear of the sleeve. The front end cover has a round hole, and the front end of the contact rod is conical. The rear end of the contact rod abuts against the trigger end of the micro switch. The spring causes the front end of the contact rod to pass through the round hole until the front end of the contact rod is stuck in the round hole.

[0013] The door control switch is reasonably designed and operates stably and reliably.

[0014] Furthermore, the sleeve diameter is equal to or less than the mounting hole diameter, the front cover diameter is greater than the mounting hole diameter, after the sleeve is inserted into the mounting hole, the front cover and the annular convex edge abut against each other, the front cover blocks the positioning notch, and the front of the front cover is lower than or flush with the front of the partition.

[0015] The concealed door switch and partition connection structure result in a neat and aesthetically pleasing appearance, and the door switch is not easily removed.

[0016] In this invention, the heating elements in both chambers are controlled by corresponding door switches. When the cabinet door is opened, the heating elements are de-energized and stop working. Compared with the prior art, this improves safety and reduces the risk of burns to users. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1, see Figure 1-4As shown, an improved vertical disinfection cabinet includes a cabinet body 1, a first cabinet door 2, and a second cabinet door 3. The cabinet body 1 contains two independent chambers: a first chamber 20 and a second chamber 30. A partition 4 separates the first chamber 20 and the second chamber 30. The first cabinet door 2 and the second cabinet door 3 are pivotally connected to the cabinet body 1. The second cabinet door 3 seals the second chamber 30. A first heating element 21 is installed in the first chamber 20, and a second heating element 31 is installed in the second chamber 30. A normally open first door control switch 5 is installed on the partition 4 corresponding to the first cabinet door 2, connected in series with the first heating element 21. A normally open second door control switch 6 is installed on the partition 4 corresponding to the second cabinet door 3, connected in series with the second heating element 31. A control device 10 is installed on the first cabinet door 2, electrically connected to both the first heating element 21 and the second heating element 31. The user controls the first heating element 21 and the second heating element 31 to enter the working state via the control device 10.

[0023] The partition 4 is provided with mounting holes 40 and mounting cavities 41 corresponding to the first door control switch 5 and the second door control switch 6, respectively. The mounting cavity 41 is connected to the outside through the mounting hole 40. The side of the mounting hole 40 is provided with two symmetrically arranged positioning notches 43. The outer sides of the first door control switch 5 and the second door control switch 6 are provided with two symmetrically arranged locking protrusions 55. The first door control switch 5 and the second door control switch 6 are inserted into the corresponding mounting holes 40. After the locking protrusions 55 pass through the positioning notches 43, they rotate in the mounting cavity 41. The locking protrusions 55 and the positioning notches 43 are misaligned to prevent the first door control switch 5 and the second door control switch 6 from disengaging from the corresponding mounting holes 40. Specifically, the partition 4 is provided with an annular protrusion 42 at the outer end corresponding to the mounting hole 40. The front of the annular protrusion 42 is lower than the front of the partition 4. The annular protrusion 42 is provided with the positioning notches 43 that connect to the mounting holes 40.

[0024] In this embodiment, the first door control switch 5 and the second door control switch 6 have the same structure. Both the first door control switch 5 and the second door control switch 6 include a front cover 51, a sleeve 52, a micro switch (not shown in the figure), a spring (not shown in the figure), and a contact rod 53. The front cover 51 is sealed and fixed to the front end of the sleeve 52. The sleeve 52 has a retaining protrusion 55 on its outer periphery. A gap 56 for clamping the annular protrusion 42 is left between the front cover 51 and the retaining protrusion 55. The micro switch is located at the bottom of the sleeve 52. The micro switch has a terminal at the rear of the sleeve 52. The front cover 51 has a circular hole 54. The front end of the contact rod 53 is conical. The rear end of the contact rod 53 abuts against the trigger end of the micro switch. The spring causes the front end of the contact rod 53 to pass through the circular hole 54 until the front end of the contact rod 53 is stuck in the circular hole 54.

[0025] During installation, the leads of the circuit inside the mounting cavity 41 in cabinet 1 are passed through and electrically connected to the corresponding terminals. The sleeve 52 is inserted into the mounting hole 40, causing the leads to retract into the mounting cavity 41. The locking protrusion 55 is aligned and inserted into the positioning notch 43 until the front cover 51 and the annular protrusion 42 abut against each other. The front cover 51 is rotated 90°, and the sleeve 52 and the locking protrusion 55 rotate 90° with the front cover 51, causing the locking protrusion 55 and the positioning notch 43 to align. At the same time, the annular protrusion 42 is placed in the gap 56 between the locking protrusion 55 and the front cover 51, thus completing the installation of the first door control switch 5 and the second door control switch 6. Because the front cover 51 is placed in the recess 44 formed by the partition and the annular protrusion, and the front cover 51 covers the positioning notch 43, the user usually cannot see the internal connection structure, making it difficult to disassemble the first door control switch 5 and the second door control switch 6.

[0026] In operation, when the first cabinet door 2 closes and seals the first chamber 20, the pressing contact rod 53 of the first cabinet door 2 actuates the trigger terminal of the micro switch, energizing the micro switch from normally open to closed, i.e., the first cabinet door 2 causes the first door control switch 5 to close and become energized. When the first cabinet door 2 opens, the spring pushes the trigger to reset, and the micro switch automatically resets and de-energizes, thus de-energizing the first heating element 21. Similarly, when the second cabinet door 3 closes and seals the second chamber 30, the pressing contact rod 53 of the second cabinet door 3 actuates the trigger terminal of the micro switch, energizing the micro switch from normally open to closed, i.e., the second cabinet door 3 causes the second door control switch 6 to close and become energized. When the second cabinet door 3 opens, the spring pushes the trigger to reset, and the micro switch automatically resets and de-energizes, thus de-energizing the second heating element 31.
