DETAILED DESCRIPTION

[0031] The embodiments of the application will be described in detail below with reference to the drawings.

[0032] Reference Figures 1-18The application provides a mobile air conditioner with inclined air outlet, which comprises a shell 1 and a volute assembly, a front cavity and a rear cavity are formed in the shell 1, a first air inlet 101 and a second air inlet are respectively arranged on the side wall of the front cavity and the side wall of the rear cavity, and a first air outlet 102 and a second air outlet 104 are respectively arranged above the front cavity and the rear cavity, wherein the second air outlet 104 is arranged between the top surface of the shell and the front end surface, specifically, an inclined air outlet surface is arranged between the top surface of the shell 1 and the front end surface of the shell 1, and the second air outlet is arranged on the air outlet surface.

[0033] Refer to Fig. 1 Figure 7 The volute assembly comprises a first volute 5 arranged in the front cavity and a second volute 6 arranged in the rear cavity, impellers are arranged in the first volute 5 and the second volute 6, and the two impellers are connected to the same motor; the first volute 5 is provided with a first air inlet hole 501 and a first air outlet hole, wherein the first air inlet hole 501 faces the first air inlet 101, an evaporator 71 is arranged on the first air inlet hole 501, and the first air outlet hole is arranged upwardly, in the embodiment, the first air outlet hole is inclined upwardly in the direction of the first air inlet 101 to form an inclined air outlet part 502, which is used as an air outlet end and can be connected to the first air outlet 102 to send cold air; the second volute is provided with a second air inlet hole and a second air outlet hole, wherein the second air inlet hole is communicated with the second air inlet, a condenser is arranged on the second air inlet hole, and the second air outlet hole is connected to the second air outlet 104 to send hot air; in the application, the first volute 5 is combined by a first half shell 5a and a second half shell 5b.

[0034] The inclined air outlet part 502 of the first volute 5 is inclined upwardly, so that the cold air can be diffused upwardly to avoid the problem of excessively large local temperature difference caused by the traditional straight blowing type air outlet; the inclined air outlet design can reduce the cold air directly blowing to the human body, and is especially suitable for long-time staying scenes such as bedrooms and offices, so as to avoid the discomfort caused by the straight blowing, the cold air is naturally sunk after being sent from the inclined upper side, the hot air is naturally risen after being sent from the inclined surface, which conforms to the air flow law and enhances the body comfort; and the cold air can be sent to a farther space area to improve the overall refrigeration efficiency and make the temperature field of the whole room more uniform.

[0035] In the present application, the first air outlet hole is curved towards the first air inlet 101 and inclined upwards, and the width of the inclined air outlet portion 502 gradually increases along the air outlet direction. The air outlet path naturally connects with the air outlet direction in the volute, and when the airflow flows along the arc trajectory, the impact loss caused by the right angle or acute angle turning is avoided, the air resistance and wind noise are reduced. At the same time, the curved structure makes the airflow form a buffer transition in the volute, reduces the vortex and turbulence phenomenon, ensures that the wind energy output by the impeller is more efficiently converted into blowing kinetic energy, and improves the actual air volume. The curved path can further enhance the parabolic diffusion characteristics of the airflow, improve the air supply distance, avoid the local high wind speed caused by direct blowing, and realize wide-area and soft blowing. The gradually increasing width of the air outlet makes the flow velocity of the airflow gradually decrease during the air outlet process, avoiding the howling or turbulent noise caused by the sudden change of the cross section. At the same time, the gradually expanding structure makes the airflow form a fan-shaped diffusion at the air outlet end, and the wind speed uniformly decreases from the center to the edge, avoiding the beam-shaped wind problem caused by traditional narrow air outlet, and improving the use comfort.

[0036] Specifically, the inclined air outlet portion 502 includes first, second, third and fourth side walls 511, 512, 513 and 514 respectively tangent to the inner wall of the first volute 5, wherein the third and fourth side walls 513 and 514 are arc surfaces curved towards the first air inlet, and the first and second side walls 511 and 512 are arc surfaces expanding outward. The tangent design makes the high-speed airflow discharged by the impeller flow naturally into the inclined air outlet portion along the inner wall of the volute, avoiding the airflow impact caused by the right angle or acute angle between the side wall and the inner wall of the volute, effectively reducing the air resistance and wind noise. At the same time, the smooth transition of the inner wall guides the airflow to flow along the fixed trajectory, reduces the local vortex and turbulence, makes the airflow velocity distribution more uniform, and ensures the stability of the air outlet. The expanding arc surface makes the airflow slowly expand during the air outlet process, and the wind speed uniformly decreases from the center to both sides, avoiding the beam-shaped wind problem of traditional narrow air outlet, improving the air outlet uniformity, and gradually reducing the airflow velocity along the air outlet direction, reducing the wind shear noise caused by the friction between high-speed airflow and air, and reducing the noise. Moreover, the uniformly diffused airflow has a wider coverage.

[0037] In this embodiment, the air guide surface at the air outlet end of the third side wall 513 and the fourth side wall 514 is an upwardly inclined arc, which makes the included angle between the air outlet direction of the inclined air outlet portion and the horizontal plane 40°-45°. The arc-shaped air guide surface guides the airflow to be smoothly sent out at a preset angle, controls the air outlet angle, and improves the actual air supply distance. The arc-shaped air guide surface makes the airflow flow along the curved surface, avoids airflow separation at the air outlet end, and reduces wind noise. The mobile air conditioner is usually placed on the ground with a height of 0.5-1 m. The inclined angle of 40°-45° can make the airflow directly reach the human activity area by passing over the furniture, avoid being blocked by the furniture, and have good air supply effect. The distance between the air outlet end of the first side wall 511 and the second side wall 512 is 80%-90% of the width of the first volute cavity 50, i.e., the width of the inclined air outlet portion is 80%-90% of the width (diameter direction) of the first volute cavity, which ensures that the air outlet has sufficient lateral coverage, while avoiding excessive widening that causes excessive loss of wind pressure, or being too small that causes beam wind phenomenon, thereby achieving an optimal balance between wide-area air supply and wind pressure maintenance.

[0038] The first volute 5 is used for sending cold air, and the second volute 6 is used for heat dissipation. An evaporator 71 is arranged at the air inlet end of the first volute 5, a condenser 72 is arranged at the air inlet end of the second volute 6, and a water pan 9 is arranged at the lower end of the volute assembly. Figures 8-10 The water pan 9 is provided with a water receiving area 91 and a water striking area 97. The water receiving area 91 is located directly below the evaporator, and the water striking area 97 is located directly below the condenser. A water striking motor is arranged in the water striking area 97, and a water wheel is arranged on the water striking motor to cool the condenser. The water receiving area 91 and the water striking area 97 are communicated through a flow channel. An overflow boss 93 is arranged in the flow channel, and an overflow hole 930 is arranged on the overflow boss 93 to control the water level in the water striking area 97. The condensed water generated by the evaporator directly drips into the water receiving area 91 below and is drained to the water striking area for water cooling, avoiding the problem of stagnant water odor caused by the traditional water pan full of water. The condensed water in the water receiving area enters the water striking area 97 through the flow channel. The water wheel driven by the water striking motor splashes water onto the surface of the condenser, uses the latent heat of evaporation of water to strengthen heat dissipation, and quickly and effectively cools the condenser to ensure stable operation of the system. The overflow boss 93 forms a water level threshold. When the water amount in the water striking area exceeds the height of the overflow hole 930, the excess water is discharged to the water tank below through the overflow hole, which precisely controls the water level in the water striking area. If the depth of the water wheel is too deep, the rotating resistance will suddenly increase, the motor current will rise, the overheat protection may be triggered or the motor may be burned out, and the blades cannot form a cutting-splashing action but push the whole water body to flow, greatly reducing the splashing atomization effect, reducing the cooling area, and affecting the splashing and cooling effect of the condenser. At the same time, the water level can be controlled to avoid overflowing to other areas due to high water level, causing internal circuit short circuit or structural rust, and ensuring the safety of operation.

[0039] In this embodiment, the water inlet end height of the overflow hole 930 is lower than the axis height of the water wheel in the water hitting area, and the immersion depth of the water wheel is greater than 1 / 4 of the diameter of the water wheel, preferably 1 / 4-1 / 3 of the diameter of the water wheel; when the immersion depth is 1 / 4 of the diameter, the water wheel blades can bring enough water film, which forms water beads under the action of centrifugal force, meeting the minimum heat dissipation requirement of the equipment; when the immersion depth is less than 1 / 4 of the diameter, the contact area of the blade with the water surface is insufficient, and the water quantity is suddenly reduced, so the rotation speed of the water wheel needs to be increased to make up for the insufficient water quantity, resulting in the increase of the power consumption and noise of the motor; when the immersion depth is 1 / 3 of the diameter, the depth of the blade cutting into the water surface is moderate, the water film is torn into small droplets under the centrifugal force, the evaporation heat absorption efficiency is significantly improved, and the power consumption of the compressor is reduced; the above design balances the atomization effect, energy consumption and noise through the optimal immersion depth on the basis of guaranteeing the minimum water quantity of the water wheel, improves the condenser heat dissipation efficiency and system stability, and has low cost and high reliability.

[0040] The water receiving area 91 in the application is strip-shaped, the length direction of which is parallel to the length direction of the evaporator, and the bottom surface of the water receiving area 91 is inclined, and water baffles 911 are staggered arranged on both sides of the water receiving area 91, that is, one end of the water baffles 911 is connected with the side wall of the water receiving area, and the other end has a gap with the other side wall, which can contain water flow, the water baffles 911 are multiple and staggered arranged, the transverse width of which is greater than 1 / 2 of the width of the water receiving area, specifically, the water baffles 911 are inclined to the water outlet direction of the water receiving area 91, that is, the length direction of the water baffles is inclined to the length direction of the water receiving area, and the length direction of the water receiving area is the water flow direction, the included angle between the length direction of the water baffles and the length direction of the water receiving area is 30-60 degrees, preferably 45 degrees, and a wave-shaped flow channel is formed in the water receiving area; a first flow channel 92 is arranged at the outlet end of the water receiving area 91, a second flow channel is arranged at the end of the first flow channel 92, the second flow channel is communicated with a water hitting area 97, an overflow boss 93 is arranged between the first flow channel 92 and the second flow channel, the top surface height of the overflow boss 93 is higher than the bottom surface height of the second flow channel and lower than the bottom surface height of the first flow channel 92, and an overflow hole 930 is arranged on the top surface of the overflow boss 93, and the upper end of the overflow hole is slightly higher than the top surface of the overflow boss, preferably, the protrusion height is 1-3 mm. The bottom surface of the water receiving area is inclined along the water outlet direction, the gravity is used to make the condensed water flow quickly to the outlet end, the drainage time is reduced, and the bacteria breeding caused by the long-term retention of stagnant water in the water receiving area is avoided; the transverse width of the water baffles is greater than 1 / 2 of the width of the water receiving area, and the water baffles are staggered arranged, so that the water flow flows along the wave-shaped path, which can control the flow rate on the one hand, avoid the water hammer noise caused by the direct impact of the water flow on the outlet of the flow channel, and on the other hand, avoid the water splashing caused by the large flow of condensed water and the movement, and improve the stability of the water flow; the top surface height of the overflow boss is higher than the bottom surface of the second flow channel and lower than the bottom surface of the first flow channel, so that the water level difference is controlled, the excess water can be orderly discharged through the overflow hole, and the risk of increasing the load of the motor or internal short circuit caused by the high water level in the water hitting area is prevented. The strip-shaped design of the above-mentioned water receiving area and the inclined bottom surface realize efficient water collection and rapid drainage, the staggered water baffles and the wave-shaped flow channel realize buffering-filtering-steady flow, the water flow characteristics are optimized, the overflow boss and the overflow hole realize accurate water level control through the physical structure. Compared with the traditional water receiving disc, the water collection efficiency and the impurity filtration rate are improved, the water level control precision of the water hitting area is high, and the heat dissipation efficiency and the operation safety of the mobile air conditioner are significantly improved.

[0041] In order to make the layout more reasonable, the second flow channel includes a first section 94, a second section 95 and a third section 96 in sequence, the water receiving area, the first flow channel and the first end are arranged at the edge position of the rear cavity, and the second section 95 and the third section 96 are arranged at the edge position of the front cavity, and the third section is communicated with the water hitting area 97 through one or more water inlet holes 960; the edge layout of the front and rear cavities maximizes the use of idle space and improves the maintenance convenience, the layout is reasonable, the flow channel direction is parallel to the length or width direction of the water receiving disc, the influence on other functional areas is reduced, and the processing and production are facilitated.

[0042] In order to avoid water shaking in the flow channel during movement, in the present application, anti-shaking ribs for preventing water shaking are arranged in the flow channel and the water hitting area, the anti-shaking ribs are multiple and staggered along the length direction of the flow channel or the water hitting area, that is, one end of the anti-shaking rib is connected with the side wall of the flow channel or the water hitting area, and the other end has a gap with the other side wall, which can contain water flow, and the staggered arrangement has a transverse width greater than 1 / 2 of the width of the water receiving area, forming a wave-shaped flow path, avoiding water splashing during movement, and improving the use reliability; when the mobile air conditioner is moved or carried, the water in the flow channel and the water hitting area will shake violently due to inertia, which may cause water overflow; the anti-shaking ribs are arranged in sequence along the length direction (with a spacing of 20-30 mm), which divides the flow channel and the water hitting area into multiple independent small chambers, effectively solving the impact force of water and the overflow problem during movement; at the same time, it can improve the overall structural strength of the water receiving plate.

[0045] The floating assembly 4 is arranged in the water tank 2 and is located at the same end of the water tank as the detection assembly 3, that is, on one side wall of the water tank, the floating assembly 4 includes an inner mounting seat 41 and a floating block 42, the inner mounting seat 41 is fixed on the inner wall of the water tank 2, and the floating block 42 is vertically and slidingly fitted on the inner mounting seat 41 and can slide up and down (float), a magnet is arranged on the floating block 42 and faces the magnetic induction switch 33, which is used for triggering the magnet of the magnetic induction switch 33 when the water level is full, when the floating block 42 moves to the upper limit position along with the water level, that is, the set full water level, the magnet can trigger the magnetic induction switch 33, and then the magnetic induction switch 33 sends an induction signal to realize alarm, the floating assembly 4 and the detection assembly 3 are arranged close to the full water level position.

[0046] This application employs non-contact detection, placing the magnetic induction switch 33 on the outside of the water tank 2. The magnet used to trigger the switch is mounted on the float 42 inside the water tank. This design eliminates the need for the magnetic induction switch 33 to directly contact the water, fundamentally avoiding the corrosion, dirt accumulation, and water quality-related malfunctions common in traditional water tank sensors. This significantly improves the long-term reliability and lifespan of the alarm device and reduces maintenance costs. The detection component and the float component are assembled independently and are both simply mechanically fixed to the outer and inner walls of the water tank, eliminating the need for complex modifications to the water tank. Easy to process and low manufacturing cost; the float 42 slides precisely vertically on the inner mounting base 41 to ensure that it can accurately follow the changes in water level. When the water level reaches the preset upper limit (i.e., full water level), the magnet on the float 42 can stably approach and trigger the external magnetic induction switch 33, so that the alarm signal can be issued in a timely and accurate manner with a fast response speed, thereby effectively preventing water tank overflow and avoiding potential losses and safety hazards; and when parts need to be replaced, the outer mounting base can be directly removed from the outside or the float can be taken out from the inside without emptying the water tank, reducing maintenance difficulty and downtime costs.

[0047] In Example 1, to facilitate the installation of the detection components and improve the stability of the water tank installation, preventing the water tank from deflecting or shaking and affecting the detection accuracy and reliability, this embodiment also includes a connecting seat 31. The connecting seat is fixed to the side wall of the water tank 2, specifically, it is set on the short side (thickness) side wall of the water tank 2. The end of the connecting seat 31 is connected to the air conditioner base, thereby strengthening and fixing the water tank 2 and preventing shaking. The external mounting seat 32 is installed on the connecting seat 31. In this embodiment, the air conditioner base includes a base body 11 and a vertical plate 12 set on the base body 11. The water tank is placed on the base body 11, and the connecting seat 31 is fixedly connected to the vertical plate. The connecting seat is directly fixedly connected to the air conditioner base, forming a secondary reinforcement of the water tank, effectively resisting the water tank deflection, tilting and shaking caused by equipment operation vibration, external collision or water flow impact, avoiding the relative position offset between the detection component and the floating component caused by the displacement of the water tank, ensuring that the upper limit position of the float-triggered magnetic induction switch always accurately corresponds to the preset full water level, eliminating water level detection error from the source.

[0048] In the embodiment, the connecting seat 31 is S-shaped and is formed by bending a metal plate. Specifically, the connecting seat 31 includes a first connecting portion 314 for connecting with the side wall of the water tank 2, the first connecting portion 314 is in a sheet (plate) shape, the head of the first connecting portion 314 is bent by 90 degrees towards the direction away from the water tank, forming a second connecting portion 313, the end of the second connecting portion 313 is reversely bent by 90 degrees, forming a third connecting portion 312, the end of the third connecting portion 312 is bent by 90 degrees towards the direction of the water tank, forming a fourth connecting portion 311 for connecting with the air conditioner base (vertical plate), and the outer mounting seat 32 is mounted on the first connecting portion 314. The connecting seat 31 is formed in a cross section similar to S-shaped after the metal plate is bent by 90 degrees for multiple times. Compared with a flat plate or a simple L-shaped structure, the material fibers at the bending positions are extruded with each other, the bending and torsion strength of the connecting seat is significantly improved, the torque generated by the weight of the water tank, the impact of water flow and external vibration can be effectively resisted, the water tank is prevented from being deviated due to the deformation of the connecting seat itself, the relative position accuracy of the detection assembly and the floating assembly is ensured from the structural root; the connecting seat in the S-shaped structure makes the weight and vibration load of the water tank transmitted to the air conditioner base through multiple paths of the connecting portions, the stress is avoided from being concentrated on a single connecting point, and the local deformation of the side wall of the water tank under stress is avoided to affect the position accuracy and detection reliability of the detection assembly and the internal floating block.

[0049] In order to realize quick connection and improve connection reliability, a positioning opening 3140 and a positioning hole 3141 are arranged on the connecting seat 31 in the embodiment, which are arranged on the first connecting part 314 in the embodiment, the positioning opening 3140 is rectangular, the positioning hole 3141 is a circular hole, the size of the positioning opening 3140 is larger than that of the positioning hole 3141; and the outer mounting seat 32 includes an outer mounting seat body 321 which is in a sheet or plate structure and can be attached to the outer wall of the water tank, a positioning boss 322 corresponding to the positioning opening 3140 and a mounting column 325 corresponding to the positioning hole 3141 are arranged on the outer side of the outer mounting seat body 321, the cross section of the positioning boss 322 is the same as the cross section shape of the positioning opening 3140 and can pass through the positioning opening 3140 to realize quick positioning of the two; the first end of the positioning boss 322 extends outward away from the side of the mounting column to form a clamping part 323; the mounting column 325 is arranged at the second end of the outer mounting seat body, i.e. the end away from the clamping part, and a mounting hole for connecting with the water tank is arranged through the mounting column 325; during assembly, the outer mounting seat 32 is placed on the inner side of the connecting seat 31, i.e. the side close to the water tank, so that the clamping part passes through the positioning opening outward and contacts the end of the positioning opening, and then the other end of the outer mounting seat is rotated with the clamping part as the hinge point until the positioning boss and the mounting column pass through the positioning opening and the positioning hole respectively, so that the outer mounting seat is attached to the water tank and the connecting seat is attached to the outer mounting seat, and then fixed by bolts. The cross section shape of the positioning opening and the positioning boss is completely matched, the mounting column (cylindrical) and the positioning hole (circular hole) are accurately corresponding, a unique shape matching mechanism is formed, the outer mounting seat and the connecting seat can be quickly guided to be aligned, the orientation problem in traditional installation is avoided, quick and accurate positioning is realized, and the assembly efficiency is improved; the clamping part contacts the end of the opening after passing through the positioning opening, a temporary hinge point is formed, at this time the outer mounting seat can be rotated around the clamping part, the operation is convenient, and the assembly process is simplified; after the positioning boss and the mounting column pass through the corresponding opening and hole, the outer mounting seat is closely attached to the connecting seat and the outer wall of the water tank, and then fastened by bolts, a double constraint of mechanical limiting and fastening is formed, compared with the bolt fixing, the contact area is increased, the connection loosening caused by equipment operation vibration or external impact can be effectively resisted, and the long-term use reliability is improved.

[0050] In order to improve the structural strength, the two sides and the tail of the first connecting part 314 are bent by 90 degrees away from the water tank to form a reinforcing part 315; the structure is simple and convenient to process, the overall improvement of the structural strength, rigidity and stability is realized, the problem of insufficient installation precision caused by deformation of the flat plate connection is solved, and the process economy and operation convenience are considered at the same time, which provides protection for accurate and stable detection.

[0051] The positioning boss 322 in the embodiment is composed of a plurality of transverse and or longitudinal reinforcing ribs, the transverse reinforcing ribs and the longitudinal reinforcing ribs form a cross-shaped or grid-shaped skeleton, the structural strength is high, the torsional strength is good, the material usage is reduced, and the manufacturing cost is reduced.

[0052] In order to achieve rapid installation of the magnetic induction switch, this application provides an installation groove for installing the magnetic induction switch 33 on the positioning boss 322. The installation groove is provided with a positioning post 324 for positioning the magnetic induction switch 33, which can improve the assembly efficiency and accuracy of the magnetic induction switch. In this embodiment, the installation groove is located between two adjacent transverse and longitudinal reinforcing ribs, which reduces the protrusion distance of the magnetic induction switch.

[0053] Example 2, see Figures 19-20 The difference between this embodiment and the above embodiments lies in the installation position of the detection component. In this embodiment, a vertical plate 12 and a support plate 14 are also included. The vertical plate 12 and the support plate 14 are located on both sides of the water tank, specifically at the two ends of the short side. That is, the distance between the vertical plate 12 and the support plate 14 is basically the same as the thickness (width) of the water tank. The detection component is set on the vertical plate 12. At the same time, an elastic component 141 is provided on the support plate 14. In this embodiment, the elastic component 141 is a spring sheet, which makes the water tank tend to move closer to the vertical plate 12, so that the floating component inside the water tank fits the detection component on the vertical plate 12, and avoids the floating component inside the water tank from detaching from the detection component on the vertical plate 12, which would affect the detection accuracy.

[0054] The floating components in this application are described below; A sliding groove 420 is formed on the float 42, which is used to accommodate the inner mounting seat 41. The upper end of the sliding groove 420 is open, so that the inner mounting seat can be sleeved into the sliding groove 420 from top to bottom and achieve sliding fit. A strip-shaped groove is formed on the side wall of the sliding groove 420, which is directed to the detection assembly 3 and has a length direction parallel to the length direction of the sliding groove 420, and is used to provide space for the connection between the inner mounting seat and the inner wall of the water tank. When the float moves to the upper limit position, the bottom surface of the inner mounting seat is in contact with the bottom surface of the sliding groove, so as to achieve limiting. A magnet is mounted on the top of the float 42 (not shown in the figure), and a mounting hole is arranged at the upper end of the float, which is used to mount the magnet bracket and the magnet. This part simultaneously seals the open end of the sliding groove 420, and serves as the limiting end of the float. The length of the sliding groove is relatively short, that is, the sliding stroke of the float is relatively short, so that only one triggering end (when the float is located at the upper limit position) and one non-triggering end (when the float is not located at the upper limit position) are needed. The structure is simple and compact, the manufacturing cost is low, the assembly is convenient, and the operation is stable and reliable. When the water level rises and drives the float to move upward to the triggering end, the magnet is close to the magnetic induction switch in the detection assembly, the magnetic induction switch is triggered to generate a signal, the alarm is realized, and it is indicated that the water level of the water tank reaches the preset high position, that is, the full water level. When the water level decreases, the float moves downward under the action of gravity and is separated from the triggering position. At this time, the magnet cannot trigger the magnetic induction switch. The stroke and volume of the float are small, which effectively reduces the material cost and space occupation. When the water level is low, the water does not contact the float. When the water level is close to full, the water surface contacts the float and drives it to move upward, triggering the alarm mechanism. The whole process responds quickly and moves reliably. Since the float only contacts the water when the water level is close to full, the risk of wear and corrosion caused by long-term immersion is reduced, and the service life is prolonged.

[0055] In the present application, one or more strip-shaped guide grooves 421 are arranged on the inner wall of the sliding groove 420, and a strip-shaped protrusion 411 corresponding to the strip-shaped guide groove is arranged on the side wall of the inner mounting seat 41. The strip-shaped protrusion 411 is located in the strip-shaped guide groove 421, so as to achieve precise sliding and avoid deflection. In the present embodiment, at least one strip-shaped guide groove is arranged on the side wall away from the detection assembly. The cooperation structure of the strip-shaped guide groove and the strip-shaped protrusion effectively improves the stability of the float during sliding, prevents the inner mounting seat from being twisted or stuck during movement, and further improves the detection accuracy and use stability.

[0056] The above only describes the preferred embodiments of the present application. It should be noted that those skilled in the art can make several improvements and refinements without departing from the technical principles of the present application. These improvements and refinements should also be considered as the protection scope of the present application.
