Description

Technical Field

[0001] The present invention relates to the technical field of sterilizing machines, and in particular to a filter temperature measuring device and a sterilizing machine. Background Art

[0002] In daily work and living environments, it is inevitable that bacteria and viruses will be everywhere in people's activity spaces, which seriously affect people's health, especially in indoor places with high population density, which is more likely to cause the spread of viruses. Sterilization and disinfection of indoor air cannot be ignored. A filter is usually installed inside the disinfection machine. Aerosols, dust and other particles containing viruses and bacteria in the air are first filtered and adsorbed on the filter, and then the filter is heated to a certain high temperature. This high temperature is used to disinfect viruses and bacteria attached to the filter. In this type of disinfection machine, the filter needs to be heated to a certain high temperature to achieve the effect of disinfecting viruses, but too high a temperature will damage the filter, affect the life of the filter, and produce odor, so the filter temperature needs to be controlled not to be too high.

[0003] Combination Figure 1 , Figure 2 As shown, in order to monitor the filter temperature in real time in the disinfection machine, a temperature sensing package is fixedly installed near the bottom of the disinfection machine to collect temperature. The smaller the distance H1 between the temperature sensing package and the filter, the closer the collected temperature is to the filter temperature, and the higher the collection accuracy. If the temperature sensing package can be placed in the filter so that it contacts the filter, the collection effect is best. During the use of the disinfection machine, the filter absorbs dust. When the dust accumulates more, it will affect the purification performance and requires users to replace it regularly. When replacing, the filter needs to be pulled out of the disinfection machine first, and then a new filter is put in. This requires that the pulling and pulling process of the filter change should be smooth, and the filter cannot interfere with the structural parts, so it is required that the temperature sensing package and the filter have a certain distance; but when the temperature sensing package is at a distance from the filter, the collected temperature is different from the actual temperature of the filter.

[0047] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] Combination Figure 1 , Figure 2As shown, it is a schematic diagram of the installation state of the temperature sensing package in the prior art. In order to monitor the filter temperature in real time in the disinfection machine, a temperature sensing package 30 is fixedly installed near the bottom of the filter 10 to collect the temperature. The temperature sensing package 30 can be installed on the temperature limiter bracket 24, and is installed in a fixed manner. The distance between the temperature sensing package and the filter is H1. As a case, the value of H1 is 28mm and cannot be adjusted. Because the temperature sensing package is far away from the filter, the temperature collected by the temperature sensing package is not the same as the actual temperature of the filter. When the controller controls the temperature, it is necessary to compensate for this sampled temperature. Affected by variables such as ambient temperature, heating power of the heating element, voltage, and fan speed, the compensation value is not a fixed value and needs to be given after a large number of experimental tests and analyses. In this way, when a new model is developed or an existing model is improved, a large number of tests must be carried out for verification, which requires more experimental resources and a long development cycle. However, when H1 is smaller, the collected temperature is closer to the filter temperature, and the collection accuracy is higher. If the temperature sensing package can be placed in the filter so that it contacts the filter, the collection effect is best, and there is no need to set a compensation value. During the use of the disinfection machine, the filter absorbs dust. When the dust accumulates more, it will affect the purification performance and requires users to replace it regularly. When replacing, the filter needs to be pulled out of the disinfection machine first, and then a new filter is put in. This requires that the filter should be pulled out smoothly during the process of changing the filter, and the filter should not interfere with the structural parts, so the temperature sensing package is required to have a certain distance from the filter; but when the temperature sensing package is at a distance from the filter, the collected temperature is different from the actual temperature of the filter. In order to solve the above contradiction, the present invention provides a filter temperature measuring device to meet the requirements of accurate detection of the filter temperature while not hindering the disassembly of the filter. The following is a detailed description of the filter temperature measuring device provided by the present invention in conjunction with specific embodiments.

[0052] Embodiment 1

[0053] Combination Figure 3-Figure 13 As shown, the filter temperature measuring device provided in this embodiment includes:

[0054] The temperature sensing element 44 is used to measure the temperature of the filter screen 10;

[0055] The temperature sensing package rotating assembly 40 has one end connected to the temperature sensing element 44 . The temperature sensing package rotating assembly 40 is used to drive the temperature sensing element 44 to selectively extend into the filter 10 .

[0056] The filter temperature measuring device provided in this embodiment connects the temperature sensing element 44 to the temperature sensing package rotating assembly 40, so that the temperature sensing package rotating assembly 40 drives the temperature sensing element 44 to selectively extend into the filter 10. In the extended state, the accuracy of the filter temperature detection is guaranteed; and in the detached state, the temperature sensing element 44 is conveniently separated from the filter 10 without interfering with the disassembly of the filter 10.

[0057] Preferably, by providing the temperature sensing package rotating assembly 40, the state conversion of the temperature sensing element 44 between being placed inside the filter 10 and being placed outside can be realized, thereby achieving the dual goals of accurately collecting temperature and smoothly replacing the filter.

[0058] Preferably, in normal use, the temperature sensing bag is inserted into the filter and in contact with the filter. The actual temperature of the filter can be collected and fed back to the controller without the need for compensation. This can not only improve the accuracy of the controller in controlling the filter temperature, but also because there is no need for compensation, there is no need to calculate the compensation value based on a large amount of test data, thus saving testing resources and shortening the development cycle.

[0059] As an optional implementation form, there are many ways for the temperature sensing package rotating assembly 40 to drive the temperature sensing element 44 to selectively extend into the interior of the filter 10, such as vertical insertion, rotary cutting, plug-in, etc.

[0060] Preferably, in this embodiment, the temperature sensing element 44 extends into the interior of the filter screen 10 by rotating under the drive of the temperature sensing package rotating assembly 40 .

[0061] Specifically, the rotation plane of the temperature sensing element 44 is perpendicular to the plane where the filter screen 10 is located, thereby ensuring that the temperature sensing element 44 can contact the filter screen 10 in a rotating state and extend into or out of the filter screen 10 .

[0062] Specifically, the temperature sensing package rotating assembly 40 includes:

[0063] An extension portion 43, wherein a first end of the extension portion 43 is used to fix the temperature sensing element 44, and a rotation axis of the extension portion 43 is arranged perpendicular to a rotation plane of the temperature sensing element 44;

[0064] The handle portion 41 is connected to the second end of the extension portion 43 and is used to rotate the extension portion 43 .

[0065] Preferably, the rotation axis of the extension portion 43 is parallel to its length direction, and the rotation axis of the extension portion 43 is perpendicular to the rotation plane of the temperature sensing element 44; and further, the rotation axis of the extension portion 43 is perpendicular to the handle portion 41, thereby ensuring that when the handle portion 41 rotates, it can drive the extension portion 43 to rotate around its rotation axis.

[0066] Preferably, the temperature sensing element 44 is vertically arranged on the extension portion 43. In normal use, the temperature sensing element 44 is rotated to a vertical state, at which time the temperature sensing element 44 is inserted into the filter 10 to ensure the detection accuracy of the filter temperature; and in a detached state, the temperature sensing element 44 is rotated to a horizontal state, at which time the temperature sensing element 44 is detached from the filter 10, and preferably, the temperature sensing element 44 is arranged parallel to the bottom of the filter 10.

[0067] Combination Figure 7 As shown, in normal use, the temperature sensing element 44 is rotated to a vertical state, the temperature sensing element 44 is inserted into the filter 10, and the distance between the temperature sensing element 44 and the bottom surface of the filter 10 is H2, wherein H2 is preferably 0mm<H2≤30mm, and in some embodiments, H2 can be 15mm. At this time, the temperature sensing element 44 is in the middle position of the filter 10 and can detect the actual temperature of the filter.

[0068] Combination Figure 8 As shown, in the detached state, the temperature sensing element 44 rotates to a horizontal state, at which time the temperature sensing element 44 is detached from the filter screen 10, and the distance between the temperature sensing element 44 and the bottom surface of the filter screen 10 is H3, wherein H2 is preferably 0mm<H2≤3mm, and in some embodiments, H2 can be 1mm, so that the filter screen 10 can be pulled out in the horizontal direction, and then the new filter screen is pushed in horizontally in the opposite direction, and the temperature sensing element 44 and the filter screen 10 will not interfere with each other during the filter screen replacement process. After the filter screen is replaced, the temperature sensing element 44 is rotated to a vertical state, and the temperature sensing element 44 is restored to a vertical state and inserted into the filter screen for normal operation and temperature collection.

[0069] Preferably, the extension portion 43 is constructed as a plate-like structure. The temperature sensing element 44 is fixed to the first end of the extension portion 43 by means of bolts and buckles.

[0070] Specifically, the filter temperature measuring device also includes:

[0071] A mounting frame, movably connected to the temperature sensing package rotating assembly 40, and used to support the temperature sensing package rotating assembly 40;

[0072] The mounting frame is provided with a rotation slot 211 , and the temperature sensing package rotation assembly 40 is provided with a rotation shaft 46 corresponding to the rotation slot 211 , and the rotation slot 211 is rotationally matched with the rotation shaft 46 .

[0073] The temperature sensing package rotating assembly 40 is movably connected to the mounting frame via a rotating shaft 46. Specifically, the temperature sensing package rotating assembly 40 rotates around a rotating groove 211 provided on the mounting frame via the rotating shaft 46, so that the temperature sensing package rotating assembly 40 drives the extension portion 43 to rotate, and further drives the temperature sensing element 44 to rotate.

[0074] Preferably, in some embodiments, the diameter of the rotating shaft 46 can be selected to be Φ11.8 mm, and correspondingly, the rotating groove 211 is configured as a semicircular groove with a diameter of Φ12 mm, thereby facilitating the relative rotation of the rotating groove 211 and the rotating shaft 46 .

[0075] Specifically, the temperature sensing package rotating assembly 40 also includes:

[0076] The positioning portion 42 is arranged parallel to the rotation plane of the temperature sensing element 44;

[0077] The positioning portion 42 is provided with a first positioning member; the mounting frame is provided with a second positioning member corresponding to the first positioning member, and the first positioning member and the second positioning member move relative to each other and switch between a first position and a second position.

[0078] As one embodiment, the first positioning member may be a convex point 47, and the second positioning member may be a concave point 212; at least one convex point 47 is provided on the positioning portion 42; at least two concave points 212 are provided on the mounting frame corresponding to the convex point 47, and the convex point 47 is selectively snap-connected with the concave point 212.

[0079] The filter temperature measuring device provided in this embodiment can facilitate the positioning of the rotation operation of the temperature sensing element 44 through the active cooperation of the first positioning member and the second positioning member, ensuring that when the handle portion 41 is operated, the temperature sensing element 44 can be accurately controlled to switch between the extended state and the disengaged state.

[0080] Preferably, the number of the concave points 212 can be three, and the three concave points 212 are respectively set at 0°, 90°, and 180° around the rotation axis. Correspondingly, the number of the convex points 47 is two, and the angle between the two convex points is 90°. Thereby ensuring that there are two convex points 47 cooperating with the two concave points 212 in both the working state and the disengaged state, ensuring the stability of the clamping state. For example, in the working state, the temperature sensing element 44 is inserted into the filter screen 10 in a vertical state, and the two convex points are respectively clamped with the first concave point and the second concave point; in the disengaged state, by rotating the handle part 41, the temperature sensing element 44 is rotated to a horizontal state to be separated from the filter screen 10, so that the two convex points are respectively clamped with the second concave point and the third concave point. Thereby, the temperature sensing package rotating assembly 40 is fixed on the outer shell of the heating cavity by the combination of the concave point and the convex point positioning, and can be rotated at a fixed position, which plays a role in positioning and preventing accidental rotation.

[0081] As a variation, the first positioning member and the second positioning member may also be in the form of a slide block and a slide groove.

[0082] Specifically, the temperature sensing package rotating assembly 40 further includes: a clamping portion 45 , which is respectively arranged on both sides of the mounting frame with the positioning portion 42 , and is used to ensure the constancy of the rotation axis when the temperature sensing package rotating assembly 40 is in a rotating state.

[0083] By clamping the clamping portion 45 and the positioning portion 42 on the two sides of the mounting frame respectively, the temperature sensing package rotating assembly 40 will not move forward or backward, and the rotation axis is kept constant in the rotating state.

[0084] Specifically, the rotating shaft 46 is disposed between the clamping portion 45 and the positioning portion 42 .

[0085] The filter temperature measuring device provided in this embodiment arranges the rotating shaft 46 between the clamping portion 45 and the positioning portion 42, thereby ensuring that when the rotating shaft 46 and the rotating groove 211 are rotated together, they can be constrained by the clamping portion 45 and the positioning portion 42 at the same time, ensuring that the temperature sensing package rotating assembly 40 does not move forward and backward during the rotation process.

[0086] Preferably, in some embodiments, the distance between the two end surfaces of the rotating shaft is 1.2 mm, that is, the distance between the clamping portion 45 and the positioning portion 42 is 1.2 mm. Correspondingly, to ensure the normal rotation of the protrusion, the protrusion height of the protrusion 47 relative to the positioning portion 42 is 1 mm.

[0087] Specifically, the mounting frame is the front end surface of the heat-generating cavity shell 21 , and the handle portion 41 is disposed outside the heat-generating cavity shell 21 .

[0088] Preferably, the wall thickness of the front end surface of the heating cavity shell 21 is 1 mm.

[0089] Specifically, when the temperature sensing element 44 is separated from the filter 10, the handle 41 gives way to the disassembly direction of the filter 10. Therefore, during the disassembly process of the filter 10, the handle 41 gives way to the disassembly direction of the filter 10, which does not cause interference and facilitates the disassembly of the filter 10.

[0090] Preferably, when the temperature sensing element 44 is separated from the filter 10, the handle portion 41 is blocked by the front end surface of the heating cavity shell 21 along the front-to-back direction, and the top end of the handle portion 41 along the up-down direction does not exceed the upper end position of the front end surface of the heating cavity shell 21.

[0092] This embodiment provides a sterilizing machine, including: a filter 10, and the filter temperature measuring device as described in the above-mentioned embodiment 1.

[0093] The sterilizer provided in this embodiment connects the temperature sensing element 44 to the temperature sensing bag rotating assembly 40, so that the temperature sensing bag rotating assembly 40 drives the temperature sensing element 44 to selectively extend into the filter 10. In the extended state, the accuracy of the filter temperature detection is guaranteed; and in the detached state, the temperature sensing element 44 is conveniently separated from the filter 10 without interfering with the disassembly of the filter 10.

[0094] Preferably, a heating element assembly 22 is also provided in the disinfector, and the heating element assembly 22 can be composed of multiple heating elements, preferably three in this embodiment. A heating cavity housing 21 is installed outside the heating element assembly 22 to form a semi-enclosed heating cavity. A filter 10 is placed on the heating cavity housing 21, and when the air heated by the heating element assembly 22 flows through the filter 10, the filter 10 is heated to reach the expected set temperature, thereby achieving the virus disinfection function.

[0095] A thermostat bracket 24 is also provided inside the heating cavity shell 21, and at least one thermostat 241 is installed on the thermostat bracket 24. By placing the thermostat 241 inside the heating cavity shell 21, the temperature inside the cavity is monitored, and an alarm or power-off processing is performed when the temperature exceeds the limit.

[0096] Preferably, a controller is further provided in the sterilizer, and the temperature sensing element 44 detects the temperature of the filter and feeds back to the controller, and the controller controls the heating temperature of the heating element assembly 22 to control the temperature of the filter.

[0097] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
