[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0030] As described in the background technology, traditional steam sterilization equipment lacks an effective steam isolation mechanism after sterilization is completed or when the sterilization chamber door needs to be opened, which causes steam to leak easily. This disordered flow of steam not only causes energy waste, but also may pose a safety hazard to operators, such as an increased risk of scalding.

[0031] In order to solve this technical problem, the utility model provides a high-temperature steam sterilizer.

[0032] Specifically, please refer to Figures 1-4 , high temperature steam sterilizer specifically includes:

[0033] A steam box 1 and a sterilization box 2 installed on the top of the steam box 1, sealing plates 3 are slidably connected to the inner walls on both sides of the sterilization box 2, the inner wall of the sterilization box 2 is provided with a steam communication cavity 201 connected to the steam box 1, a second air outlet 302 connected to the steam communication cavity 201 is provided on the side wall of the sterilization box 2, and a first air outlet 301 corresponding to the second air outlet 302 is provided on the sealing plate 3.

[0034] The high-temperature steam sterilizer provided by the present utility model realizes the on-demand supply and shutdown of steam through the precise cooperation of the sealing plate 3 connected by sliding with the first air outlet 301 and the second air outlet 302, effectively avoiding the unnecessary loss of steam in the non-sterilization state, significantly reducing energy consumption; preventing steam from overflowing, reducing the risk of scalding operators, and improving the safety of the workplace.

[0035] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0037] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0038] Example 1, please refer to Figures 1-4 , a high-temperature steam sterilizer, including a steam box 1 and a sterilization box 2 installed on the top of the steam box 1. Sealing plates 3 are slidably connected to the inner walls on both sides of the sterilization box 2. A steam communication cavity 201 communicating with the steam box 1 is provided on the inner wall of the sterilization box 2. A second air outlet 302 communicating with the steam communication cavity 201 is opened on the side wall of the sterilization box 2. A first air outlet 301 corresponding to the second air outlet 302 is opened on the sealing plate 3; the present application realizes the on-demand supply and shutdown of steam through the precise cooperation of the sealing plate 3 connected by sliding with the first air outlet 301 and the second air outlet 302, effectively avoiding the unnecessary loss of steam in the non-sterilization state, significantly reducing energy consumption; preventing steam from overflowing, reducing the risk of scalding operators, and improving the safety of the workplace.

[0039] Furthermore, as shown in Figure 3 and Figure 4 , the tops of the two sealing plates 3 both penetrate through the sterilization box 2 and extend above the sterilization box 2. A sealing ring is sleeved on the outer surface of the sealing plate 3, and the sealing ring is connected to the top of the sterilization box 2. The sealing ring can improve the sealing performance at the connection between the sterilization box 2 and the sealing plate 3.

[0040] Example 2, further optimize the high-temperature steam sterilizer provided in Example 1. Specifically, as shown in Figure 3 and Figure 4As shown in the figure, a notch 306 is provided at the top of the sealing plate 3. After the sealing plate 3 descends, the notch 306 can connect the inside of the sterilization chamber 2 with the outside, so that the residual steam in the sterilization chamber 2 can be discharged. After sterilization is completed, a certain amount of steam usually remains in the sterilization chamber 2. If these residual steams are not discharged in time, they may suddenly gush out during subsequent operations, posing a danger to the operators. The setting of the notch 306 provides a discharge channel for the residual steam, enabling the steam to be smoothly released into the external environment.

[0041] Further, as Figure 2 and Figure 3 shown in the figure, a connecting frame 304 is fixedly connected between the tops of the two sealing plates 3. A cylinder 305 is connected between the connecting frame 304 and the sterilization chamber 2. The cylinder 305 can drive the two sealing plates 3 to lift and lower synchronously through the connecting frame 304.

[0042] Further, as Figure 3 shown in the figure, an exhaust fan 4 is fixedly installed on the connecting frame 304. The exhaust fan 4 corresponds to the position of one of the notches 306. The setting of the exhaust fan 4 can accelerate the discharge of the steam in the sterilization chamber 2 from the notch 306 below the exhaust fan 4. The exhaust fan 4 can actively generate air flow to accelerate the discharge speed of the residual steam. After sterilization is completed, discharging the residual steam as soon as possible can shorten the operation time and improve work efficiency. On the other hand, the forced exhaust of the exhaust fan 4 can ensure the discharge of the residual steam, avoiding the accumulation of the residual steam in the sterilization chamber 2 and causing potential hazards to the equipment and operators.

[0043] Further, as Figure 3 shown in the figure, both sides of the sealing plate 3 are slidably connected with limit seats 303. The limit seats 303 are fixedly connected to the inner wall of the sterilization chamber 2. The limit seats 303 can limit the sealing plate 3 to improve the stability of the sealing plate 3 and the sealing performance when the sealing plate 3 seals the second air outlet 302.

[0044] Example 3 further optimizes the high-temperature steam sterilizer provided in Example 1 or 2. Specifically, as Figure 3 and Figure 4 shown in the figure, a transmission shaft 202 is installed in the sterilization chamber 2 through bearings. A plurality of storage mesh trays 203 are fixedly sleeved on the outer surface of the transmission shaft 202. The storage mesh trays 203 are used to carry the items to be sterilized by the lamp.

[0045] Further, as Figure 3 shown in the figure, the top end of the transmission shaft 202 passes through the top of the sterilization chamber 2. A sealing bearing is connected between the outer surface of the transmission shaft 202 and the top wall of the sterilization chamber 2. A motor 204 is installed on the top of the sterilization chamber 2. The motor 204 is fixedly connected to the top end of the transmission shaft 202. The motor 204 can drive the transmission shaft 202 and the storage mesh trays 203 to rotate to improve the uniformity of sterilization.

[0046] Further, as Figure 1 shown, a door 205 is hinged to the front of the sterilization chamber 2. A locking device is provided between the door 205 and the sterilization chamber 2, and a gasket is provided on the door 205. The door 205 can seal the sterilization chamber 2.

[0047] Further, as Figure 4 shown, a heater 101 is installed in the steam box 1. One side of the steam box 1 is communicated with a water injection pipe 102 and a drain pipe 103. Sealing caps are provided on both the water injection pipe 102 and the drain pipe 103. The water injection pipe 102 is used for adding water, and the drain pipe 103 is used for draining water. The sealing cap is threadedly connected to the water injection pipe 102 and the drain pipe 103.

[0048] The use process of the high-temperature steam sterilizer provided by the present utility model is as follows:

[0049] Place the items to be sterilized on the storage tray 203, close the door 205, heat the water in the steam box 1 through the heater 101 to generate water vapor. The water vapor enters the sterilization chamber 2 through the steam communication cavity 201, the second air outlet 302 and the first air outlet 301 to sterilize the items on the storage tray 203. After sterilization is completed, the cylinder 305 drives the two sealing plates 3 to descend through the connecting frame 304, so that the first air outlet 301 is staggered from the second air outlet 302, and the sealing plate 3 blocks the second air outlet 302, while the notch 306 communicates the inside of the sterilization chamber 2 with the outside. Open the exhaust fan 4, so that the remaining steam in the sterilization chamber 2 is discharged from the notch 306 below the exhaust fan 4, and the other notch 306 is used for the outside air to enter the sterilization chamber 2. After the steam is discharged, open the door 205 and take out the items on the storage tray 203.
