Description

Technical Field

[0001] This utility model relates to the field of programmed cooling instrument technology, and in particular to an inner wall cleaning device for programmed cooling instruments. Background Technology

[0002] A programmed cooling system is a device that precisely controls the cooling rate and temperature gradient through a preset program. Its core function is to provide a stable and controllable low-temperature environment for biological samples, industrial materials, or experimental environments, avoiding sample damage caused by sudden temperature changes. It has important applications in medical, scientific research, and industrial fields.

[0003] After long-term operation, the walls of the cooling chamber of existing programmed cooling instruments are prone to accumulate impurities such as sample residues and cryoprotectant crystals. The accumulation of impurities in the chamber can lead to problems such as reduced cooling efficiency and risk of sample contamination. Existing cleaning methods for the cooling chamber usually require manual cleaning of the inner walls of the chamber using corresponding tools. However, existing cleaning tools are cumbersome to operate and have low cleaning efficiency. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a device for cleaning the inner wall of a programmable cooling instrument, thereby improving the cleaning efficiency of the inner wall of the cooling chamber.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a cleaning device for the inner wall of a programmable cooling instrument, comprising a positioning frame, a cleaning component, and a constraint component;

[0006] The positioning frame is detachably mounted on the instrument body and located above the cooling chamber;

[0007] The cleaning component consists of a cleaning frame slidably mounted on the positioning frame and a cleaning assembly movably disposed inside the cleaning frame. The cleaning frame extends vertically into the cooling chamber and maintains an operating gap between its periphery and the inner wall of the chamber.

[0008] The cleaning assembly is used to fill gaps and clean the cavity walls;

[0009] The constraint component is disposed on the cleaning frame and connected to the cleaning assembly, and is used to constrain the movement of the cleaning assembly.

[0010] Furthermore, the cleaning rack has a rectangular frame structure and multiple grooves are provided around its bottom.

[0011] The cleaning assembly includes a plurality of first cleaning plates that are slidably disposed in each of the slide grooves, and each first cleaning plate is used to clean the corresponding inner wall of the chamber.

[0012] It also includes a first elastic unit disposed in each of the slide grooves and connected at both ends to the cleaning frame and the corresponding first cleaning plate, and each of the first elastic units applies a thrust to the corresponding first cleaning plate in a direction away from the center of the cleaning frame.

[0013] Furthermore, each of the first cleaning plates is provided with a compensation component;

[0014] The compensation component includes two second cleaning plates that are respectively slidably disposed at both ends of the first cleaning plate;

[0015] It also includes a second elastic unit disposed between each of the second cleaning plates and the first cleaning plate, the second elastic unit being used to apply a thrust to the corresponding second elastic unit in a direction away from the center of the corresponding first cleaning plate.

[0016] Furthermore, the cleaning rack is equipped with a handle, and each of the first cleaning plates has a limit groove on its top;

[0017] The constraint component consists of a connecting frame, a constraint plate, and a third elastic unit;

[0018] The connecting frame is vertically slidably mounted on the top of the cleaning frame, and one end of it is provided with a lever, which is vertically slidably mounted on the handle;

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0035] Please see Figure 1-8 This utility model discloses an inner wall cleaning device for a programmable cooling instrument, including a positioning frame 1, a cleaning component 2 and a restraining component 3;

[0036] The positioning frame 1 is detachably mounted on the instrument body 01 and located above the cooling chamber 02;

[0037] The cleaning component 2 consists of a cleaning frame 21 vertically slidably mounted on the positioning frame 1 and a cleaning assembly 22 movably disposed inside the cleaning frame 21. The cleaning frame 21 extends vertically into the cooling chamber 02 and maintains an operating gap between its periphery and the inner wall of the chamber.

[0038] The cleaning component 22 is used to fill gaps and clean the cavity walls;

[0039] The constraint component 3 is mounted on the cleaning rack 21 and connected to the cleaning assembly 22 to constrain the movement of the cleaning assembly 22.

[0040] In practice, when the cooling chamber 02 needs to be cleaned, the staff will place the positioning frame 1 on the instrument body 01, and then move the cleaning frame 21 downward to the bottom of the chamber. Then, the constraint component 3 will be released from the constraint of the cleaning component 22. At this time, the cleaning component 2 will extend and contact the inner wall of the chamber. Then, the staff will pull up the cleaning frame 21 to make it move the cleaning component 22 upward, so that the cleaning component 2 can clean the impurities attached to the inner wall.

[0041] In this utility model, after the positioning frame 1 is set on the instrument body 01, the operator moves the cleaning frame 21 to the bottom of the chamber, and then releases the constraint of the constraint component 3 on the cleaning component 22, so that the cleaning component 22 extends out and contacts the inner wall of the chamber. Then the operator drives the cleaning frame 21 to rise so that the cleaning component 22 cleans the impurities on the inner wall of the chamber from bottom to top, thereby improving the cleaning efficiency.

[0042] It should be noted that the positioning frame 1 is equipped with a magnetic attraction unit at the connection between it and the instrument body 01. When the positioning frame 1 is connected to the instrument body 01, its magnetic attraction unit can provide sufficient magnetic attraction force to attract the instrument body 01, thereby helping to constrain the positioning frame 1 and prevent the positioning frame 1 from moving accidentally. When the staff needs to remove the positioning frame 1, the staff can apply force to separate the positioning frame 1 from the instrument body 01.

[0043] In one embodiment, the cleaning rack 21 has a rectangular frame structure, and grooves 211 are provided on the bottom circumference.

[0044] The cleaning assembly 22 includes a plurality of first cleaning plates 221 that are slidably disposed in each slide groove 211. Each first cleaning plate 221 is used to clean the corresponding inner wall of the chamber. The constraint member 3 is connected to each first cleaning plate 221 and is used to constrain the sliding of each first cleaning plate 221.

[0045] It also includes a first elastic unit 222, which is respectively disposed in each chute 211 and connected at both ends to the cleaning frame 21 and the corresponding first cleaning plate 221, and each first elastic unit 222 applies a thrust to the corresponding first cleaning plate 221 in a direction away from the center of the cleaning frame 21.

[0046] With this design, when the inner wall of the cavity needs to be cleaned, the staff releases the constraint component 3 from the restriction of each first cleaning plate 221. At this time, each first elastic unit 222 loses its constraint and drives the corresponding first cleaning plate 221 to extend away from the center of the cleaning frame 21 until its cleaning surface contacts the inner wall of the cavity, thereby filling the working gap. Then the cleaning frame 21 moves upward, and each first cleaning plate 221 wipes the inner wall of the corresponding cavity from bottom to top, thereby cleaning the impurities attached to its inner wall.

[0047] Preferably, the first elastic unit 222 can be a spring from the prior art.

[0048] It should be noted that each of the first cleaning plates 221 is equipped with a detachable wiping strip on its cleaning end. The wiping strip can reduce the damage of the first cleaning plate 221 to the cooling chamber 02 while ensuring cleaning efficiency. After the wiping strip has finished cleaning the chamber, it can be manually disassembled for centralized cleaning so that it can be reused multiple times.

[0049] In one embodiment, each of the first cleaning plates 221 is provided with a compensation component 4;

[0050] The compensation component 4 includes two second cleaning plates 41 that are slidably disposed at both ends of the first cleaning plate 221. The cleaning end of the second cleaning plate 41 is flush with the cleaning end of the first cleaning plate 221 and is used to clean impurities between two adjacent first cleaning plates 221. Each second cleaning plate 41 has an inclined surface at its protruding end.

[0051] It also includes a second elastic unit 42 disposed between each second cleaning plate 41 and the first cleaning plate 221, the second elastic unit 42 being used to apply a thrust to the corresponding second elastic unit 42 in a direction away from the center of the corresponding first cleaning plate 221.

[0052] With this design, when each of the first cleaning plates 221 extends out of the corresponding groove 211, there will be a cleaning dead angle between the two first cleaning plates 221 (such as the included angle at the connection of the two inner walls). At this time, each of the second elastic units 42 loses its constraint and drives the corresponding second cleaning plate 41 to extend away from the center of the first cleaning plate 221 until the two adjacent second cleaning plates 41 extend into the cleaning dead angle and their inclined surfaces come into contact with each other, thereby cleaning the impurities in the cleaning dead angle and further improving the cleaning quality.

[0053] Preferably, the second elastic unit 42 can be a spring from the prior art.

[0054] It should be noted that the cleaning end of the second cleaning plate 41 is detachably equipped with the same wiping strip as the first cleaning plate 221.

[0055] In one embodiment, the cleaning rack 21 is provided with a handle 23, and the top of each cleaning plate is provided with a slot 212, and the top of each first cleaning plate 221 is provided with a limiting groove 2211 corresponding to the slot 212. When the cleaning plate is stored in the corresponding sliding groove 211, the limiting groove 2211 on the cleaning plate is coaxially arranged with the corresponding slot 212.

[0056] The constraint component 3 includes a connecting frame 31 that is vertically slidably disposed on the top of the cleaning frame 21. The connecting frame 31 has a rectangular frame structure and a lever 32 is provided at one end. The lever 32 is vertically slidably sleeved on the handle 23.

[0057] It also includes multiple constraint plates 33 respectively disposed at the bottom of the connecting frame 31 and vertically sliding through the corresponding slide groove 211, and inserted in the corresponding limiting groove 2211. Each constraint plate 33 is used to restrict the movement of the corresponding first cleaning plate 221.

[0058] A third elastic unit 34 is also provided between the connecting frame 31 and the cleaning frame 21, which is used to apply a vertically downward pulling force to the connecting frame 31.

[0059] With this design, when the staff moves the cleaning frame 21 to the bottom of the chamber by using the handle 23, the staff lifts the lever 32 to move the connecting frame 31 upward. At this time, each constraint plate 33 rises and exits the corresponding limit groove 2211, each first elastic unit 222 loses its constraint and drives the corresponding first cleaning plate 221 to move. At this time, the bottom of each constraint plate 33 contacts the top of the corresponding first cleaning plate 221.

[0060] When it is necessary to retract the first cleaning plate 221, the staff press each first cleaning plate 221 until each first cleaning plate 221 is retracted into the corresponding slide groove 211. At this time, the third elastic unit 34 drives the connecting frame 31 to move downward so that each constraint plate 33 is inserted into the corresponding limit groove 2211 again.

[0061] Preferably, the third elastic unit 34 can be a spring from the prior art.

[0062] It should be noted that each chute 211 has a guide slope on both sides. When the first cleaning plate 221 is drawn into the chute 211, the slope of the second cleaning plate 41 contacts the guide slope of the chute 211 and is guided into the first cleaning plate 221.

[0063] In one embodiment, the positioning frame 1 has two vertically arranged guide rods 11 at its bottom. Each guide rod 11 is disposed in the cooling chamber 02 and is vertically slidably connected to the corresponding end of the cleaning frame 21. The guide rods 11 are used to guide the movement of the cleaning frame 21.

[0064] With this design, when the staff applies force to the cleaning frame 21, each guide rod 11 guides the cleaning frame 21 to move vertically, so as to avoid accidental deviation.

[0065] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0066] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0067] Additionally, "multiple" refers to two or more.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
