Description

Technical Field

[0001] This utility model relates to the field of water bath sterilization technology, specifically to a water bath sterilization device. Background Technology

[0002] Water bath sterilization is primarily based on moist heat sterilization, a method widely used in the pharmaceutical and food industries. It utilizes superheated circulating water as a heating medium, leveraging the water's excellent fluidity and heat transfer properties to ensure uniform heating of all parts of the product, achieving sterilization. This method offers advantages such as good temperature uniformity, ease of operation, and low cost, making it particularly suitable for high and low temperature sterilization of liquids or sealed packaged goods in glass or plastic bottles, ensuring product quality and safety.

[0003] The utility model patent with application number CN202323346093.7 and publication number CN221556861 U (hereinafter referred to as "Prior Art 1") discloses a water bath sterilization device for packaging bottles, including a vessel body. The top surface of the vessel body is threadedly connected to a top cover, and the top cover is threadedly connected to a cylinder body. A packaging bottle is placed inside the cylinder body. Multiple through slots are opened on the outer side of the cylinder body, and water pipes are installed in four of the through slots. An assembly seat is fixedly installed at the other end of each water pipe. The top cover is threadedly connected to the vessel body and the cylinder body. The packaging bottle can be placed inside the cylinder body first, and the cylinder body and the top cover can be fixed by threads. Then, the top cover and the cylinder body can be fixed by threads.

[0004] The specification of prior art 1 discloses a water bath sterilization device for packaging bottles. During use, the top cover allows for quick removal and placement of the packaging bottles during the water bath process, preventing scalding. However, in actual application, the cylinder slides between the through groove and the water pipe, but the through groove restricts the movement of the water pipe, causing the water pipe to sterilize the carrier only from a fixed direction. This results in the carrier not being able to be sterilized in all directions, leading to poor sterilization effect. Summary of the Invention

[0005] This invention provides a water bath sterilization device, which aims to solve the problem that existing sterilization tanks cannot uniformly sterilize the device to be sterilized from all directions, resulting in poor sterilization effect.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A water bath sterilization device includes a sterilization tank, a spraying device, and a feeding device. The feeding device is slidably mounted on the sterilization tank, and the spraying device is rotatably mounted inside the sterilization tank body.

[0008] The spraying device includes a drive structure and a spraying structure. The drive structure is installed on the sterilization tank, and the spraying structure is rotatably installed inside the sterilization tank and connected to the drive structure.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model mainly includes a sterilization tank, a spraying device, and a feeding device. In actual use, the operator loads the device or item to be sterilized into the material cylinder, then pushes the support plate, causing the slide rod to slide inside the sliding hole, so that the support plate is placed into the support groove. Then, the opening of the sterilization tank is closed, forming a seal inside the sterilization tank. The spraying structure is then controlled to spray high-temperature hot water. Simultaneously, the drive structure is controlled to operate, driving the spraying structure to rotate inside the sterilization tank. The high-temperature hot water is evenly sprayed through the spraying structure and enters the material cylinder through the through-hole, thereby sterilizing the contents of the material cylinder. The device or item to be sterilized is subjected to high-temperature sterilization. After the sterilization tank is filled with high-temperature hot water, the drive mechanism is stopped.

Detailed Implementation

[0026] The present invention will be further described below with reference to the embodiments. The described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0027] Please see Figure 1-Figure 4 As shown, this embodiment discloses a water bath sterilization device, including a sterilization tank 101, a spraying device and a feeding device. The feeding device is slidably installed on the sterilization tank 101, and the spraying device is rotatably installed inside the sterilization tank 101.

[0028] The spraying device includes a drive structure and a spraying structure. The drive structure is installed on the sterilization tank 101, and the spraying structure is rotatably installed inside the sterilization tank 101 and connected to the drive structure. The drive device is used to drive the spraying structure to rotate inside the sterilization tank 101.

[0029] The feeding device includes a material cylinder 102 and a support plate 103. The material cylinder 102 is provided with several through holes 104 and a material inlet and outlet. The material cylinder 102 is installed at one end of the support plate 103. The support plate 103 is provided with several sliding rods 105. The sterilization tank 101 is provided with several sliding holes 106. The sliding rods 105 are used to slide inside the sliding holes 106. The opening of the sterilization tank 101 is provided with a support groove 107. The support groove 107 and the inner wall of the sterilization tank 101 form a stepped structure. The support plate 103 is used to be installed in the support groove 107.

[0030] This utility model mainly includes a sterilization tank 101, a spraying device, and a feeding device. In actual use, the operator loads the device or item to be sterilized into the material cylinder 102, then pushes the support plate 103, causing the slide rod 105 to slide inside the sliding hole 106, so that the support plate 103 is placed inside the support groove 107. Then, the opening of the sterilization tank 101 is closed, forming a seal inside the sterilization tank 101. Then, the spraying structure is controlled to spray high-temperature hot water. At the same time, the drive structure is controlled to operate, driving the spraying structure to rotate inside the sterilization tank 101. The high-temperature hot water is evenly sprayed through the spraying structure and enters the material cylinder 102 through the through hole 104, thereby sterilizing the material cylinder 101. 2. For devices or items requiring sterilization, high-temperature sterilization is performed. After the sterilization tank 101 is filled with high-temperature hot water, the drive structure is stopped. The high-temperature hot water inside the sterilization tank 101 performs a secondary water bath sterilization on the devices or items requiring sterilization inside the material cylinder 102. After sterilization, the hot water inside the sterilization tank 101 is drained, the opening of the sterilization tank 101 is opened, the support plate 103 is pulled out, and the devices or items in the material cylinder 102 are removed, completing the sterilization process. The advantage of this setup is that the device or item inside the material cylinder 102 is sterilized for the first time by the rotation of the spray structure, and then a secondary water bath sterilization is performed by the high-temperature hot water filling the sterilization tank 101, resulting in a better sterilization effect.

[0031] In some embodiments, the drive structure includes a motor 108 and a transmission mechanism. The motor 108 is fixedly mounted on the sterilization tank 101 and is used to drive the spraying structure to rotate through the transmission mechanism.

[0032] In actual use, the staff drives the motor 108 to rotate, and after the motor 108 rotates, it controls the rotation of the spraying structure through the transmission mechanism.

[0033] In some embodiments, the spraying structure includes a drive shaft 109, a water pipe 110, a multi-port connector 111, and a spray pipe 112. The drive shaft 109 is rotatably and sealed to the sterilization tank 101. The drive shaft 109 is connected to the motor 108 through a transmission mechanism. The drive shaft 109 has a water passage hole 104. The water pipe 110 is installed inside the water passage hole 104 through a bearing. The water pipe 110 is connected to a water source. The multi-port connector 111 is installed at the end of the drive shaft 109 away from the water pipe 110. Each branch of the multi-port connector 111 is equipped with one of the spray pipes 112.

[0034] In actual use, after the motor 108 rotates, it controls the transmission shaft 109 to rotate through the transmission mechanism. After the transmission shaft 109 rotates, it drives the bearing to rotate as well. Since the water pipe 110 is connected to the water passage hole 104 inside the transmission shaft 109 through the bearing, the water pipe 110 will not rotate after the transmission shaft 109 rotates. After the transmission shaft 109 rotates, it drives the multi-port connector 111 and the spray pipe 112 to rotate. The spray pipe 112 sprays high-temperature hot water to sterilize the device or item in the material cylinder 102 at high temperature.

[0035] As an optional implementation, in this embodiment, the multi-way connector 111 is specifically a three-way connector. The main path of the three-way connector is fixedly connected to the drive shaft 109 and communicates with the water passage hole 104 inside the drive shaft 109. High-temperature hot water enters the three-way connector through the main path, and finally enters the spray pipe 112 through the branch path, and finally sprays out from the spray pipe 112.

[0036] It should be noted that, in this embodiment, the purpose of setting up the transmission mechanism is to facilitate the installation of the motor 108 and the water pipe 110.

[0037] In some embodiments, the spray pipe 112 is provided with a plurality of nozzles 113, which are used to communicate with the interior of the spray pipe 112.

[0038] In actual use, the purpose of setting the nozzle 113 is to increase the water pressure so that the high-temperature hot water is sprayed out from the spray pipe 112 through the nozzle 113 and acts on the device or item that needs to be sterilized.

[0039] In some embodiments, the spray pipe 112 is provided with a plurality of spray holes 114, the spray holes 114 are provided with external threads, the end of the nozzle 113 is provided with internal threads, and the nozzle 113 is threadedly connected to the spray holes 114.

[0040] In actual use, the threaded connection between the spray pipe 112 and the nozzle 113 makes it easy to connect the nozzle 113 and the spray pipe 112, facilitates the replacement of the nozzle 113, and improves the sealing effect between the nozzle 113 and the spray pipe 112.

[0041] In some embodiments, a mounting bracket 115 is provided on the sterilization tank 101, and the motor 108 is connected to the sterilization tank 101 through the mounting bracket 115.

[0042] In actual use, the purpose of setting up the mounting bracket 115 is to facilitate the installation of the motor 108.

[0043] In some embodiments, a sealing cap 116 is hinged to the opening of the sterilization tank 101. The bottom surface of the sealing cap 116 contacts the upper end surface of the opening of the sterilization tank 101 and is used to press the support plate 103 into the support groove 107.

[0044] As an optional implementation, in this embodiment, the sealing cover 116 is sealed to the sterilization tank 101 by several bolts. The sealing cover 116 is used to close the opening so that the inside of the sterilization tank 101 is sealed. When the slide rod 105 contacts the bottom of the slide hole 106, the sealing cover 116 can also restrict the position of the entire feeding device, so that the feeding device can be installed more stably inside the sterilization tank 101.

[0045] In some embodiments, the transmission mechanism includes a driving pulley 117, a driven pulley 118, and a belt 119. The driving pulley 117 is fixedly mounted on the output shaft of the motor 108, the driven pulley 118 is fixedly mounted on the transmission shaft 109, and the belt 119 is sleeved on the driving pulley 117 and the driven pulley 118.

[0046] In actual use, the motor 108 rotates and drives the drive pulley 117 to rotate. After the drive pulley 117 rotates, it drives the driven pulley 118 to rotate through the friction of the belt 119, which in turn drives the transmission shaft 109 to rotate.

[0047] In some embodiments, a pulley is provided on the outer wall of the spray pipe 112, and a limiting track is provided on the inner surface of the sterilization tank 101, with the pulley slidably installed inside the limiting track.

[0048] In actual use, when the motor 108 drives the spray pipe 112 to rotate, the pulley is always in contact with the inner wall of the sterilization tank 101. The purpose of setting the limit track is to position the sliding of the pulley laterally, so that the rotation of the spray pipe 112 is more stable.
