Description

Technical Field

[0001] The present application relates to the technical field of bathroom heaters, and in particular to an ultraviolet sterilization device and a bathroom heater. Background Art

[0002] As living standards continue to improve, consumers' demands for product functions are also gradually increasing. Because bathrooms are in humid conditions all year round, bacteria are prone to breed. In this case, using bathroom heaters to sterilize the bathroom has gradually become a demand.

[0003] Traditional bathroom heaters have functions such as air drying and negative ion sterilization. Negative ion sterilization technology relies on the blowing function of the bathroom heater to diffuse the generated negative ions into the bathroom. If only the negative ion sterilization function is turned on without the blowing function, the sterilization effect is poor, and the blowing function will produce noise. Traditional sterilization devices also include ultraviolet sterilization lamps, which are installed on the bathroom heater to sterilize the bathroom. Since the shell of a traditional bathroom heater is generally plastic, it will be damaged by long-term exposure to ultraviolet rays, and the ultraviolet sterilization lamp is exposed to the outside of the shell, which also affects the overall aesthetics of the bathroom heater.

DETAILED DESCRIPTION

[0051] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0053] like Figures 1 to 5 As shown, an embodiment of the present application provides an ultraviolet sterilization device 5, which is applied to a bathroom heater to sterilize the bathroom.

[0054] Specifically, the ultraviolet sterilization device 5 includes:

[0055] A housing having a first installation window 101;

[0056] An ultraviolet generator is rotatably mounted at the first mounting window 101; a first driving mechanism 54 is connected to the ultraviolet generator and is used to drive the ultraviolet generator to rotate between the first position and the second position;

[0057] The ultraviolet generator includes an ultraviolet lamp tube 52 and a shielding member 51 arranged on one side of the ultraviolet lamp tube 52. When the ultraviolet generator is located at the first position, the shielding member 51 rotates to between the ultraviolet lamp tube 52 and the shell, and the ultraviolet lamp tube 52 is exposed in the first installation window 101; when the ultraviolet generator is located at the second position, the shielding member 51 rotates to the outside of the ultraviolet lamp tube 52 to shield the ultraviolet lamp tube 52. The ultraviolet sterilization device 5 provided in the embodiment of the present application installs the ultraviolet generator at the first installation window 101 of the shell, and the first driving mechanism 54 drives the ultraviolet generator to rotate between the first position and the second position; when ultraviolet sterilization is required, the first driving mechanism 54 drives the ultraviolet generator to rotate to the first position, and the ultraviolet lamp 52 is exposed at the first installation window 101, and ultraviolet rays can be emitted from the first installation window 101 for sterilization. At this time, the shielding member 51 is located between the ultraviolet lamp 52 and the shell, and the ultraviolet rays generated by the ultraviolet lamp 52 are isolated to avoid irradiating the shell and causing damage to the shell, thereby improving the service life; when the ultraviolet sterilization function is not needed, the first driving mechanism 54 drives the ultraviolet generator to rotate to the second position, and the shielding member 51 rotates to the outside of the ultraviolet lamp 52 to close the first installation window 101. From the outside, the ultraviolet lamp 52 is hidden between the shielding plate and the shell, and the ultraviolet lamp 52 cannot be seen from the appearance, thereby improving the overall aesthetics.

[0058] Furthermore, in some embodiments of the present application, the shielding member 51 is a sleeve with an arc-shaped cross section, and the sleeve is sleeved on the outer surface of the ultraviolet lamp tube 52 .

[0059] Specifically, the sleeve can be a cylinder with a diameter greater than the diameter of the ultraviolet lamp tube 52. The sleeve is open at both ends along the axial direction and has an opening along the axial direction. When the sleeve is sleeved on the ultraviolet lamp tube 52, a portion of the ultraviolet lamp tube 52 is exposed from the axial opening of the sleeve, and the ultraviolet light emitted by the ultraviolet lamp tube 52 is emitted from the axial opening of the sleeve. Due to the blocking effect of the sleeve, the ultraviolet light emitted by the ultraviolet lamp tube 52 cannot be emitted through the sleeve where the sleeve is.

[0060] Furthermore, in some embodiments of the present application, the axial opening of the sleeve is smaller than or equal to the first installation window 101. When the ultraviolet generator is rotated to the first position, the ultraviolet light emitted by the ultraviolet lamp 52 can only be emitted from the first installation window 101, so as to prevent the ultraviolet light from irradiating the housing and causing damage to the housing.

[0061] Here, “the opening of the sleeve along the axial direction is smaller than or equal to the first installation window 101” means that the width of the opening on the sleeve is smaller than or equal to the width of the first installation window 101, and the length of the opening on the sleeve is smaller than or equal to the length of the first installation window 101. The width of the opening is the size of the opening along the circumferential direction, and the length of the opening is the size of the opening along the axial direction.

[0062] Furthermore, in some embodiments of the present application, the shielding member 51 is a metal member. When the shielding member 51 rotates to the first position, the shielding member 51 is located between the ultraviolet lamp tube 52 and the housing to block ultraviolet rays from irradiating the housing.

[0063] Generally, the shell is a plastic part. When the ultraviolet light emitted by the ultraviolet lamp 52 irradiates the shell for a long time, it will cause certain damage to the shell and accelerate the aging of the shell. Therefore, in the embodiment of the present application, the shielding member 51 is set as a metal part. When the ultraviolet lamp 52 is working, the shielding member 51 rotates between the ultraviolet lamp 52 and the shell to isolate the ultraviolet lamp 52 from the shell, protect the shell, and increase the life of the shell.

[0064] Furthermore, in some embodiments of the present application, the ultraviolet generator also includes two rotating sleeves 53 , the two rotating sleeves 53 are respectively sleeved on the two ends of the ultraviolet lamp tube 52 , and the two ends of the shielding member 51 are respectively fixedly connected to the rotating sleeves 53 .

[0065] Specifically, the first driving mechanism 54 is fixedly connected to one of the rotating sleeves 53, and the rotating sleeve 53 at the other end is disposed on the housing and is rotatably connected to the housing. The first driving mechanism 54 is connected to the rotating sleeve 53, and can drive the rotating sleeve 53 and the shielding member 51 to rotate synchronously, or drive the rotating sleeve 53, the shielding member 51 and the ultraviolet lamp tube 52 to rotate synchronously, so as to change the relative position of the shielding member 51 and the first installation window 101, so that when the ultraviolet generator is started, ultraviolet rays can be emitted from the first installation window 101, and when the ultraviolet generator is turned off, the shielding member 51 hides the ultraviolet lamp tube 52.

[0066] Specific, combined Figure 5As shown, the rotating sleeve 53 includes a sleeve 531 and a sleeve end cover 532. One end of the sleeve 531 is sleeved on the ultraviolet lamp tube 52, and the sleeve end cover 532 is fixed to the end of the sleeve 531 away from the ultraviolet lamp tube 52. A first connecting portion 5321 is provided on the sleeve end cover 532, and a second connecting portion 512 for cooperating with the first connecting portion 5321 is provided at a corresponding position of the shielding member 51. Specifically, the first connecting portion 5321 is a first connecting hole arranged along the axial direction of the sleeve 531, and the second connecting portion 512 is a second connecting hole arranged along the axial direction of the sleeve 531. The first connecting hole and the second connecting hole are connected together by fasteners such as bolts and screws. A first mounting hole 5322 is provided on the side of the sleeve end cover 532 away from the sleeve 531, which is used to be fixedly connected with the first driving mechanism 54. The first driving mechanism 54 adopts a stepping motor. By controlling the rotation direction and rotation angle of the stepping motor, the position change of the rotating sleeve 53 and the shielding member 51 is realized.

[0067] Further, combined with Figure 3 and Figure 4 As shown, in some embodiments of the present application, the shielding member 51 has two layers, namely an inner plate 510 and an outer plate 511, wherein the cross-sections of the inner plate 510 and the outer plate 511 are both arc-shaped, and the shapes of the cross-sections of the inner plate 510 and the outer plate 511 are approximately semicircular, and the centers of the inner plate 510 and the outer plate 511 are not in the same position. It can be understood that the arc length of the cross-section of the inner plate 510 is less than the semicircle, and the arc length of the cross-section of the outer plate 511 is greater than the semicircle, and the distance between the inner plate 510 and the outer plate 511 gradually decreases from the two ends along the center in the circumferential direction, and the two ends of the outer plate 511 along the circumferential direction are fixedly connected to the two ends of the inner plate 510 along the circumferential direction respectively to form a cavity between the inner plate 510 and the outer plate 511.

[0068] The shielding member 51 is configured as a two-layer structure. On the one hand, the structural strength of the shielding member 51 can be improved. On the other hand, since the inner plate 510 and the outer plate 511 are both thin-walled structures, only one layer of the structure is not conducive to fixation with the sleeve end cover 532. The shielding member 51 is configured as a two-layer structure, which provides space for the setting of the second connecting part 512, thereby facilitating the fixed connection between the shielding member 51 and the rotating sleeve 53.

[0069] Furthermore, in order to facilitate the fixed connection between the rotating sleeve 53 and the shielding member 51, a recess 5311 is formed at a position corresponding to the outer circumferential surface of the sleeve 531 and the shielding member 51. The inner wall of the inner plate 510 is clamped in the recess 5311 and fits with the outer circumferential surface of the sleeve 531. The setting of the recess 5311 provides a reference for the installation of the shielding member 51, realizes the preliminary positioning of the shielding member 51, and avoids errors in the installation position of the shielding member 51.

[0070] Furthermore, in some embodiments of the present application, a protrusion is formed on the outer surface of the sleeve 531 at the recess 5311 to form a snap-in block 5312, and the snap-in block 5312 is inserted into a cavity formed by the inner plate 510 and the outer plate 511. The cooperation between the snap-in block 5312 and the cavity limits the rotational freedom of the shielding member 51 relative to the rotating sleeve 53, avoids the relative movement of the shielding member 51 along the rotating sleeve 53, and realizes the pre-positioning of the shielding member 51. When the snap-in block 5312 is inserted into the cavity, the first connecting portion 5321 corresponds exactly to the position of the second connecting portion 512.

[0071] Specifically, the first connection portion 5321 is located in the cavity and is fixedly connected to the inner plate 510 and / or the outer plate 511. There are multiple first connection portions 5321, which are arranged at intervals along the circumference of the inner plate 510 or the outer plate 511, and a first limiting groove 513 is formed between two adjacent first connection portions 5321. The number of the clamping blocks 5312 is equal to the number of the first limiting grooves 513 and they are plugged in one-to-one correspondence.

[0072] In some embodiments of the present application, the first connection portion 5321 is a first connection hole, which is surrounded by a thin-walled cylindrical structure. The first connection portion 5321 is fixedly connected to the inner plate 510, or fixedly connected to the outer plate 511, or can be connected to both the inner plate 510 and the outer plate 511. Two adjacent first connection portions 5321 together with the inner plate 510 and the outer plate 511 enclose a first limiting groove 513, and the clamping blocks 5312 are inserted axially in the first limiting groove 513 one by one.

[0073] Furthermore, in some embodiments of the present application, the ultraviolet lamp tube 52 may be fixed or may rotate synchronously with the rotating sleeve 53 and the shielding member 51 .

[0074] Specifically, the ultraviolet lamp tube 52 is fixedly connected to the shell, and the first driving mechanism 54 is fixedly connected to the rotating sleeve 53, driving the rotating sleeve 53 and the shielding member 51 to rotate synchronously, only changing the position of the shielding member 51, and the ultraviolet lamp tube 52 is fixed. When ultraviolet sterilization is needed, the first driving mechanism 54 drives the rotating sleeve 53 and the shielding member 51 to rotate to the first position, so that the ultraviolet lamp tube 52 is exposed to the first installation window 101. When ultraviolet sterilization is not needed, the first driving mechanism 54 drives the rotating sleeve 53 and the shielding member 51 to rotate to the second position, and the shielding member 51 shields the ultraviolet lamp tube 52 to prevent the ultraviolet lamp tube 52 from being exposed and affecting the aesthetics.

[0075] Alternatively, the ultraviolet lamp tube 52 is fixedly connected to the rotating sleeve 53, and the first driving mechanism 54 is fixedly connected to the rotating sleeve 53, driving the rotating sleeve 53, the shielding member 51 and the ultraviolet lamp tube 52 to rotate synchronously.

[0076] Furthermore, in some embodiments of the present application, the ultraviolet sterilization device 5 also includes a signal sensing unit, which includes at least one of an infrared sensor, a microwave radar sensor and a door magnetic sensor, and the signal sensing unit is used to detect whether there are any living things in the sterilization space.

[0077] The ultraviolet sterilization device 5 further includes a controller. The output end of the signal sensing unit is communicatively connected to the input end of the controller. The controller is used to control the first driving mechanism 54 to operate according to the signal detected by the signal sensing unit.

[0078] Working principle: when the sterilization function of the ultraviolet sterilization device 5 is turned on, and the signal sensing unit detects that there is no one in the bathroom, the controller controls the first driving mechanism 54 to drive the ultraviolet generator to rotate to the first position, so that the baffle plate rotates between the ultraviolet lamp tube 52 and the shell, and the ultraviolet lamp tube 52 is exposed from the first installation window 101 to perform ultraviolet sterilization in the bathroom; when the signal sensing unit detects that there is someone in the bathroom, the controller controls the first driving mechanism 54 to delay the action until the person leaves and then turns on the ultraviolet sterilization function; similarly, when the ultraviolet sterilization function is turned off, the controller controls the first driving mechanism 54 to drive the ultraviolet generator to rotate to the second position, and the baffle plate hides the ultraviolet lamp tube 52 in the first installation window 101, thereby improving the aesthetics of the ultraviolet sterilization device 5 when not in use.

[0079] Traditional bathroom heaters have functions such as blow-drying and negative ion sterilization. The negative ion sterilization technology relies on the blowing function of the bathroom heater to diffuse the generated negative ions into the bathroom. If only the negative ion sterilization function is turned on without the blowing function, the sterilization effect is not good, and turning on the blowing function will produce noise.

[0080] Combination Figures 1 to 12 As shown, some embodiments of the present application further provide a bathroom heater, which combines the ultraviolet sterilization device 5 in the above embodiment with the bathroom heater, so that the bathroom heater has a dual sterilization effect of ultraviolet sterilization and negative ion sterilization, thereby improving the sterilization efficiency.

[0081] Specifically, the shell of the ultraviolet sterilization device 5 in the above embodiment can be the shell of a bathroom heater. That is to say, when the ultraviolet sterilization device 5 is combined with the bathroom heater structure, there is no need to provide a shell for the ultraviolet sterilization device 5. A first installation window 101 can be provided on the shell of the bathroom heater, and the ultraviolet generator can be installed at the first installation window 101.

[0082] like Figure 1As shown, the shell includes a panel 1 and a back cover, and the panel 1 and the back cover are buckled to enclose an installation space together. A first installation window 101 is formed on the panel 1. Specifically, two connecting ears 102 are provided at one end of the panel 1, and an arc-shaped installation groove 103 is provided on the connecting ear 102. Two rotating sleeves 53 of the ultraviolet generator are respectively arranged in the two installation grooves 103. The length of the installation groove 103 is greater than the length of the rotating sleeve 53. A first driving mechanism 54 is also installed in one of the installation grooves 103. The first driving mechanism 54 is located at one end of the ultraviolet generator and is fixedly connected to the rotating sleeve 53. A motor end cover 55 is provided at the installation groove 103 where the first driving mechanism 54 is installed, and the first driving mechanism 54 is enclosed in the installation groove 103; in addition to the rotating sleeve 53 being installed in the other installation groove 103, the remaining space along the axial direction is used for wiring. A display end cover 56 is provided at the installation groove 103 to close the installation groove 103, and the wiring is enclosed inside the installation groove 103 to avoid exposure, thereby improving aesthetics and safety. The display cover 8 is sleeved on the installation position of the display end cover 56 and the panel 1.

[0083] During installation, the bathroom heater can be installed on the wall or the ceiling of the bathroom, the panel 1 is the side facing away from the wall or the ceiling of the bathroom, and the rear cover faces the wall or the ceiling of the bathroom. The rear cover can be the shell of the main unit 13 of the bathroom heater, and the main unit 13 is provided with a controller, a fan and other structures.

[0084] Furthermore, an air outlet 104 is provided on the shell of the bathroom heater, the swing device 3 is arranged corresponding to the air outlet 104, and the negative ion generating device is arranged in the shell corresponding to the swing device 3.

[0085] Specifically, the air outlet 104 is arranged on the panel 1, the swing device 3 is located between the main unit 13 and the air outlet 104, the swing device 3 has an air inlet end and an air outlet end, the air inlet end of the swing device 3 is arranged corresponding to the fan in the main unit 13, and the air outlet end of the swing device 3 is arranged corresponding to the air outlet 104; the negative ion generating device is located at the air inlet end of the swing device 3, and the negative ions generated by the negative ion generating device are blown into the swing device 3 by the action of the fan, and diffused into the bathroom by the action of the swing device 3.

[0086] The negative ion sterilization device and the ultraviolet sterilization device 5 can be controlled separately. When the noise generated by the negative ion sterilization of the user is relatively loud, the ultraviolet sterilization device 5 can be used alone for sterilization. Even if the air blower is not turned on, a good sterilization effect can be achieved.

[0087] Furthermore, in some embodiments of the present application, the wind swing device 3 includes an air guide shell 3A, a second driving mechanism 41, a third driving mechanism and a swinging fan blade 35, the air guide shell 3A has an air guide channel, the swinging fan blade 35 is rotatably arranged in the air guide channel 3B, the second driving mechanism 41 is connected to the air guide shell, and is used to drive the air guide shell 3A and the swinging fan blade 35 to rotate in a first direction, and the third driving mechanism 42 is connected to the swinging fan blade 35, and is used to drive the swinging fan blade 35 to rotate in a second direction.

[0088] It should be understood that the "first direction" and "second direction" here are different directions, for example, the first direction is the front-to-back direction, and the second direction is the left-to-right direction; or the first direction is the left-to-right direction, and the second direction is the front-to-back direction. The front, back, left, and right mentioned here and in the following text are used for convenience, and are intended to illustrate that the wind guide housing and the swinging blades 35 have different swinging directions, and are not used to limit the specific installation position and installation angle of the swinging device 3 on the bathroom heater.

[0089] Furthermore, at least one side surface of the swing blade 35 is provided with a first groove 351 , and there are multiple first grooves 351 , which are evenly distributed on the side surface of the swing blade 35 .

[0090] Specifically, the first groove 351 is arranged on the side of the swinging fan blade 35 corresponding to the second direction. In some embodiments of the present application, the second direction is the left and right direction, and the first groove 351 is arranged on the left and right sides of the swinging fan blade 35. The setting of the first groove 351 increases the surface area of ​​the left and right sides of the swinging fan blade 35, thereby increasing the contact area between the swinging fan blade 35 and the wind, breaking up the passing wind, and further diffusing the range of negative ion outlet.

[0091] The swinging device 3 provided in the embodiment of the present application utilizes the second driving mechanism 41 of the dual motor assembly 4 to drive the air guide housing 3A to swing along the first direction (such as the front-to-back direction), and utilizes the third driving mechanism 42 to drive the swinging blades 35 to swing along the second direction (such as the left-to-right direction), thereby realizing an effective two-way swinging function, with a wider air supply range and a better heating effect for the bathroom heater; the swinging device 3 of the present application can increase the area of ​​the swinging blades 35 by setting the first groove 351, thereby better improving the air guiding effect. The swinging device 3 of the present application is suitable for installation at the air outlet 104 of the air-heated bathroom heater, and the two-way swinging structure can be set using the limited air outlet 104 space, so that the bathroom heater can realize an effective two-way swinging function.

[0092] Furthermore, in some embodiments of the present application, the shape of the first groove 351 is a trumpet shape that gradually shrinks from the groove mouth to the groove bottom. When the wind hits the swinging fan blade 35, it flows into the groove bottom of the first groove 351 through the side wall of the first groove 351, and flows out from the groove wall on the other side of the first groove 351, thereby better improving the wind guiding effect.

[0093] Further, combined with Figure 6 and Figure 7 As shown, the air guide housing 3A includes a first connecting plate 32, a second connecting plate 31 and a third connecting plate 36. The first connecting plate 32 and the second connecting plate 31 are arranged opposite to each other. There are two third connecting plates 36. The two third connecting plates 36 are respectively connected between the ends of the first connecting plate 32 and the second connecting plate 31. The first connecting plate 32, the second connecting plate 31 and the two third connecting plates 36 jointly enclose the air guide channel 3B. The air guide housing 3A is different from the air guide plate. It constrains the range of the air guide channel 3B so that the wind passing through it flows through the air guide channel 3B. By controlling the rotation direction and rotation angle of the air guide housing 3A, the air outlet can be adjusted in the front and rear directions.

[0094] There are multiple swinging blades 35 , and the multiple swinging blades 35 are arranged at intervals along the length direction of the first connecting plate 32 , and the length direction of the first connecting plate 32 is consistent with the second direction.

[0095] Further, combined with Figure 8 As shown, in some embodiments of the present application, a fixed shaft 352 is provided on both sides of the swing blade 35 opposite to the first connecting plate 32 and the second connecting plate 31, and a second mounting hole 321 rotatably matched with the fixed shaft 352 is provided at corresponding positions of the first connecting plate 32 and the second connecting plate 31.

[0096] A transmission member 33 is provided in the air guide channel, and the third driving mechanism 42 is connected to the swinging blades 35 through the transmission member 33, so as to drive the plurality of swinging blades 35 to swing synchronously.

[0097] Specifically, the two fixed rotating shafts 352 on the swinging blade 35 are arranged opposite to each other, and are respectively rotatably matched with the second mounting holes 321 on the first connecting plate 32 and the second connecting plate 31. The transmission member 33 is connected to the plurality of swinging blades 35. The third driving mechanism 42 drives the transmission member 33 to perform linear reciprocating motion, thereby driving the plurality of swinging blades 35 to rotate synchronously. The two sides of the swinging blade 35 are respectively rotatably connected to the first connecting plate 32 and the second connecting plate 31. The first connecting plate 32 and the second connecting plate 31 limit the swinging blade 35 from both sides. Without other limiting structures, the swinging blade 35 can be fixed between the first connecting plate 32 and the second connecting plate 31, thereby preventing the swinging blade from being separated from the wind guide housing, and improving the stability of the overall structure of the swinging device 3.

[0098] Further, combined with Fig. 9 As shown, in some embodiments of the present application, a linkage shaft 353 is provided on the swinging fan blade 35, and the linkage shaft 353 and one of the fixed shafts 352 are arranged at the same side of the swinging fan blade 35 at intervals, and a third mounting hole 331 is provided on the transmission member 33, and the linkage shaft 353 is rotatably matched with the third mounting hole 331. When the third driving mechanism 42 drives the transmission member 33 to perform linear motion, the swinging fan blade 35 performs translational motion in a fan-shaped trajectory with the fixed shaft 352 as a circle and the axial center distance between the fixed shaft 352 and the linkage shaft 353 as a radius, so that the transmission member 33 drives the swinging fan blade 35 to rotate and swing around the fixed shaft 352, thereby realizing the swinging of the swinging fan blade 35 along the second direction.

[0099] Furthermore, the transmission member 33 is slidably connected to the first connecting plate 32 , and the transmission member 33 slides along the length direction of the first connecting plate 32 .

[0100] Specifically, a first slide groove is provided on the first connecting plate 32, and the first slide groove is arranged along the length direction of the first connecting plate 32. The transmission member 33 is slidably arranged in the first slide groove. The first slide groove limits the sliding direction of the transmission member 33 to ensure that the connecting member can only move back and forth in a straight line along the length direction of the first connecting plate 32, thereby making the multiple swinging blades 35 swing synchronously in the left and right directions.

[0101] Further, combined with Figure 8 As shown, in some embodiments of the present application, the third mounting hole 331 is an oblong hole, and the length direction of the third mounting hole 331 is perpendicular to the length direction of the transmission member 33, so that when the transmission member 33 moves back and forth along a straight line, the linkage shaft 353 can slide in the third mounting hole 331, thereby driving the swinging fan blade 35 to swing in a fan-shaped trajectory with the fixed shaft 352 as the center and the axial center distance between the fixed shaft 352 and the linkage shaft 353 as the radius. Of course, the third mounting hole 331 is not limited to an oblong hole, and can also be an arc hole of other shapes, etc. The length direction of the third mounting hole 331 is not limited to being perpendicular to the length direction of the transmission member 33, and the angle between the two can be slightly greater than or slightly less than 90 degrees.

[0102] Furthermore, two parallel first limiting plates 322 are protruded from the inner side wall of the first connecting plate 32, the length direction of the first limiting plates 322 is parallel to the length direction of the first connecting plate 32, and a first sliding groove is formed between the two first limiting plates 322;

[0103] A plurality of L-shaped second limiting plates 3221 are arranged at intervals along the length direction at one end of the first limiting plate 322 away from the first connecting plate 32 , and the second limiting plates 3221 on two first limiting plates 322 are arranged opposite to each other in a staggered manner.

[0104] Specifically, the second limiting plate 3221 includes a connecting portion and a limiting portion, the connecting portion is arranged in a direction perpendicular to the first connecting plate 32, and the limiting portion is arranged in a direction parallel to the first connecting plate 32, and the limiting portion is arranged corresponding to the first slide groove. When the transmission member 33 is installed in the first slide groove, the limiting portion limits the transmission member 33 on the side of the transmission member 33 away from the first connecting plate 32, preventing the first connecting plate 32 from escaping from the first slide groove from the notch of the first slide groove, thereby further improving the stability of the installation structure.

[0105] A plurality of L-shaped second limiting plates 3221 are disposed on each first limiting plate 322 , and the second limiting plates 3221 on two first limiting plates 322 are arranged alternately to limit the transmission member 33 at multiple locations along the length direction of the transmission member 33 .

[0106] Furthermore, it also includes an air guide sleeve 2, which is fixed on the panel 1, and an air guide shell is located in the air guide sleeve 2, and two ends of the air guide shell 3A are rotatably connected to the air guide sleeve 2 respectively.

[0107] In specific implementation, the air guide sleeve 2 can be a guide sleeve with open ends. The inner cavity shape of the air guide sleeve 2 is adapted to the outer contour shape of the air guide shell 3A. The air guide shell 3A is installed inside the air guide sleeve 2. Support shafts are set at both ends of the air guide shell 3A. A shaft hole corresponding to the support shaft is set on the air guide sleeve 2. The support shaft is passed through the shaft hole, so that the air guide shell 3A can swing along the first direction in the air guide sleeve 2 with the swinging fan blade 3B35.

[0108] The second driving mechanism 41 includes a second driving motor 411 and a second output shaft 413. The second driving motor 411 is connected to the second gear 412 to drive the second gear 412 to rotate. The second gear 412 is engaged with the second output shaft 413 to drive the second output shaft to rotate. The second output shaft 413 passes through the air guide sleeve 2 and is connected to the air guide shell, driving the air guide shell and the swinging fan blades 35 to rotate along the first direction in the air guide sleeve 2.

[0109] The third driving mechanism 42 includes a third driving motor 421, a third gear 422 and a third output shaft 423. The third driving motor 421 is connected to the third gear 422 to drive the third gear 422 to rotate. The third output shaft 423 is meshed with the third gear 422 so that the third output shaft 423 can move back and forth in a straight line. The third output shaft 423 passes through the air guide sleeve and the air guide shell and is connected to the transmission member 33, driving the transmission member 33 to do linear reciprocating motion, thereby driving the multiple swinging blades 35 to rotate synchronously along the second direction.

[0110] Furthermore, in order to improve the compactness of the overall structure, the second output shaft 413 can be set as a hollow shaft, and the third output shaft 423 passes through the second output shaft 413. In this way, only one matching hole needs to be set on the air guide shell. The second output shaft 413 is passed through the matching hole and fixedly connected to the matching hole. The third output shaft 423 passes through the matching hole from the second output shaft 413 and is fixedly connected to the transmission part 33 inside the air guide shell.

[0111] One end of the transmission member 33 is clamped with the third output shaft 423 of the third driving mechanism 42 through the clamping assembly 34. Specifically, one end of the transmission member 33 is provided with a first clamping member 342, and the first clamping member 342 is provided with a semicircular groove. The transmission member 33 also includes a second clamping member 341, and the second clamping member 341 is also provided with a semicircular groove. The semicircular groove on the first clamping member 342 and the semicircular groove on the second clamping member 341 can together form a circular hole. After passing through the air guide housing, the third output shaft 423 first cooperates with the semicircular groove on the first clamping member 342, and then the second clamping member 341 is correspondingly connected with the first clamping member 342, and the third output shaft 423 is fixed between the first clamping member 342 and the second clamping member 341. The clamping structure composed of the first clamping member 342 and the second clamping member 341 cannot enter the first slide groove because its size is larger than that of the first slide groove, and thus it can also play a role in limiting the travel of the transmission member 33.

[0112] Fig.11 This is a schematic diagram of the structure when the negative ion generator and ultraviolet generator of the bathroom heater are turned on at the same time. Fig.12 It is a structural diagram when the negative ion generating device and the ultraviolet generating device of the bathroom heater are turned off at the same time; when the blowing function of the bathroom heater is turned on, the fan in the main unit 13 starts to work for blowing, and when the airflow passes through the swing device 3, the negative ion generating device is turned on at the same time by default, and the swing device 3 is turned on, wherein the air guide shell and the swinging fan blades 35 can be controlled separately, and after the controller outputs the control signal of the air guide shell and the swinging fan blades 35, it controls the second driving mechanism 41 and the third driving mechanism to respectively drive the air guide shell to rotate in the first direction and the swinging fan blades 35 to rotate in the second direction.

[0113] Specifically, the negative ion generating device includes a negative ion generator 10 and a negative ion carbon brush 11, which are electrically connected, wherein the negative ion generator 10 is fixed on the panel 1, and the negative ion carbon brush 11 is fixed on the mounting frame 9 between the panel 1 and the host 13.

[0114] A speaker assembly 12 is also installed on the panel 1, which can give an alarm or play the information of the bathroom heater.

[0115] A functional PCB board 6 and a display PCB board 7 are also provided on the panel 1, and the controller of the bathroom heater is integrated on the functional PCB board or the display PCB board.

[0116] To sum up, the bathroom heater provided in the embodiment of the present application, when the negative ion generating device is turned on, can utilize the oscillating wind device 3 to diffuse the diffusion range of negative ions, thereby optimizing the negative ion sterilization effect; in addition, the ultraviolet sterilization device 5 and the negative ion generating device have a dual sterilization effect, thereby improving the sterilization efficiency; when the user feels that the noise is loud, the ultraviolet sterilization device 5 can be used alone for sterilization, and even if the air is not blown, a good sterilization effect can be achieved, thereby solving the problem of high noise when only the negative ion sterilization device needs to be turned on for blowing.
