Description

Technical Field

[0001] This invention relates to the field of bathroom ventilation technology, specifically a prefabricated bathroom ventilation system and the bathroom thereof. Background Technology

[0002] Fresh air exchange is designed and developed based on the principle that supplying air to one side of a sealed room and drawing air to the other side will create a "fresh air flow field" in the room. It relies on mechanical air supply and exhaust to force the formation of a fresh air flow field within the system, and is a system that keeps the indoor air clean and fresh at all times.

[0003] For example, Chinese patent CN208154718U discloses a bathroom ventilation device, including an inner cylinder with a fan inside, an outer cylinder coaxially sleeved on the inner cylinder, and openings at both ends of both the inner and outer cylinders. A ventilation chamber is formed between the outer wall of the inner cylinder and the inner wall of the outer cylinder. Several support rods are provided in the ventilation chamber, and the support rods are arranged radially along the outer cylinder. One end of the support rod is fixedly connected to the inner cylinder, and the other end of the support rod is fixedly connected to the outer cylinder. An air bladder layer is coaxially sleeved on the outer cylinder, and a wear-resistant layer is coaxially sleeved on the air bladder layer.

[0004] However, the above solutions have the following shortcomings: the fresh air device in the above application has a relatively simple structure and can only exhaust or intake air through a fan. However, in summer, the high temperature can cause the sewer pipes to back up and smell. Exhausting air alone often cannot effectively remove the odor. At the same time, running the ventilation device for a long time consumes a lot of electricity. Therefore, we have introduced a prefabricated bathroom fresh air ventilation system and its bathroom. Summary of the Invention

[0005] The purpose of this invention is to provide a fresh air exchange system for a prefabricated bathroom and the bathroom thereof, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A prefabricated bathroom ventilation system includes a system body with a ventilation cavity inside. Two sets of mounting frames are movably installed at the lower end of the ventilation cavity. Several sets of movable plates are movably connected inside the mounting frames. Several sets of through holes are opened on the outer side of the movable plates. A sponge is placed inside the movable plate, and absorbent cotton strips are placed inside the sponge. One end of the absorbent cotton strip is fixedly connected to the movable plate, and a first protective tube is sleeved on the outer side of the absorbent cotton strip. The other ends of the three sets of absorbent cotton strips extend out of the movable plate and are sleeved in the second protective tube.

[0008] The other end of the second protective tube extends into the mounting cavity and is inserted into the liquid storage box, which is located within the mounting cavity, which is situated within the system body. The end of the movable plate furthest from the first protective tube extends into the connecting cavity, which is situated within the system body. A T-shaped toothed rod is movably connected to the lower end of the connecting cavity, and the T-shaped toothed rod meshes with teeth located within one end of the movable plate.

[0009] The mounting cavity has guide grooves on both sides, and guide rods are slidably connected in the guide grooves. The guide rods are fixedly connected to the liquid storage box. The liquid storage box has sliding cavities on both sides, and T-shaped locking rods are movably connected in the sliding cavities. The end of the T-shaped locking rod away from the sliding cavity is engaged in a locking groove, which is located in the guide groove. A first spring is fixedly connected in the sliding cavity, and the other end of the first spring is fixedly connected to the T-shaped locking rod.

[0010] Preferably, the T-shaped rack slides within a T-shaped groove, the T-shaped groove being located at the lower end of the connecting cavity, a second spring is fixedly connected within the T-shaped groove, the other end of the second spring is fixedly connected to the T-shaped rack, a semi-circular gear meshes with the upper end of the T-shaped rack, the semi-circular gear is fixedly connected to the output end of the first motor, and the first motor is fixedly connected within the system body.

[0011] Preferably, the upper end of the mounting frame is provided with a heating tube, which is fixedly connected to the ventilation cavity. A fan is provided on the upper side of the heating tube, which is fixedly connected to the output end of the second motor. The second motor is fixedly connected to the main body of the system.

[0012] Preferably, the upper end of the system body is fixedly connected to a ventilation hose by bolts, and the lower end of the T-shaped locking rod is fixedly connected to a lever, with the end of the lever away from the T-shaped locking rod passing through a groove and extending out of the liquid storage box.

[0013] In addition, to achieve the above objectives, the present invention also provides a bathroom, including the fresh air exchange system of the prefabricated bathroom.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: by installing two sets of system main bodies, simultaneous air exchange and air intake can be achieved, or one set of system main bodies can be installed for air exchange and air intake. By adding fragrance liquid into the storage box and installing it into the installation cavity, when the absorbent cotton strip guides the fragrance in the storage box into the movable plate, the fragrance liquid absorbed by the sponge can be brought into the prefabricated bathroom by the rotation of the fan, which has the effect of purifying the air and reducing power consumption. At the same time, when the fan draws in new air, the air entering the bathroom will be warmed by the heating tube, which can be used in winter. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 The present invention provides a technical solution:

[0022] Example 1:

[0023] A fresh air ventilation system for a prefabricated bathroom includes a system body 1. A ventilation cavity 23 is provided within the system body 1. Two sets of mounting frames 7 are movably installed at the lower end of the ventilation cavity 23. The mounting frames 7 are installed to the top of the prefabricated bathroom by two sets of screws. When the mounting frames 7 need to be removed for maintenance or replacement, the screws can be unscrewed to remove the mounting frames 7. Several sets of movable plates 8 are movably connected within the mounting frames 7. Several sets of through holes 29 are provided on the outer side of the movable plates 8. The through holes 29 allow the odor of the fragrance liquid inside the sponge 9 to dissipate. A sponge 9 is provided inside the movable plate 8, and an absorbent cotton strip 28 is provided inside the sponge 9. One end of the absorbent cotton strip 28 is fixedly connected to the movable plate 8.

[0024] The absorbent cotton strip 28 is fitted with a first protective tube 30 on the outside. The other end of the three sets of absorbent cotton strips 28 extends out of the movable plate 8 and is fitted into the second protective tube 15. The absorbent cotton strips 28 located in the three sets of first protective tubes 30 will gather in the second protective tube 15 after extending out of the movable plate 8. When the absorbent cotton strip 28 in the second protective tube 15 absorbs the fragrance liquid in the liquid storage box 5, the fragrance liquid enters the movable plate 8 along the absorbent cotton strip 28. The other end of the second protective tube 15 extends into the installation cavity 2 and is inserted into the liquid storage box 5. When the smell in the prefabricated bathroom is unpleasant, you can add your favorite fragrance liquid to the liquid storage box 5.

[0025] After the liquid is added, push the liquid storage box 5 into the mounting cavity 2. The liquid storage box 5 is set in the mounting cavity 2, which is located in the system body 1. The end of the movable plate 8 away from the first protective tube 30 extends into the connecting cavity 24, which is located in the system body 1. A T-shaped toothed rod 6 is movably connected to the lower end of the connecting cavity 24. The T-shaped toothed rod 6 meshes with the tooth 10, which is located in one end of the movable plate 8. Turn on the first motor 11 to drive the semi-circular gear 27 to start rotating. The rotation of the semi-circular gear 27 drives the T-shaped toothed rod 6 to move towards the position of the second spring 26. At this time, the movable plate 8 begins to swing in one direction under the mutual cooperation of the tooth 10 and the T-shaped toothed rod 6.

[0026] Guide grooves 3 are provided on both sides of the mounting cavity 2. Guide rods 4 are slidably connected in the guide grooves 3 and are fixedly connected to the liquid storage box 5. During the pushing process of the liquid storage box 5, it is necessary to ensure that the guide rods 4 move along the guide grooves 3 to prevent the T-shaped locking rods 21 at both ends of the liquid storage box 5 from not corresponding to the locking grooves 22. Sliding cavities 18 are provided on both sides of the liquid storage box 5. T-shaped locking rods 21 are movably connected in the sliding cavities 18. The end of the T-shaped locking rod 21 away from the sliding cavity 18 is engaged in the locking groove 22. The locking groove 22 is opened in the guide groove 3. A first spring 31 is fixedly connected in the sliding cavity 18. The other end of the first spring 31 is fixedly connected to the T-shaped locking rod 21. When the liquid storage box 5 is pushed into the bottom of the mounting cavity 2, the pressure on the two sets of levers 20 is released. Under the elastic force of the first spring 31, the two sets of T-shaped locking rods 21 will engage in the corresponding locking grooves 22. At this time, the installation of the liquid storage box 5 is completed.

[0027] Example 2:

[0028] Based on Example 1, in order to enable the movable plate 8 to swing back and forth so that the fragrance liquid in the sponge 9 can be evenly dispersed, and at the same time to make the fresh air brought in warm in winter, the T-shaped toothed rod 6 is slidably connected in the T-shaped groove 25. The T-shaped groove 25 is opened in the lower end of the connecting cavity 24. A second spring 26 is fixedly connected in the T-shaped groove 25. The other end of the second spring 26 is fixedly connected to the T-shaped toothed rod 6. When the semi-circular gear 27 disengages from the T-shaped toothed rod 6, the T-shaped toothed rod 6 returns to its original position under the elastic force of the second spring 26. At the same time, the movable plate 8 will swing in the opposite direction. When the semi-circular gear 27 contacts the T-shaped toothed rod 6 again, the movable plate 8 will swing again. The upper end of the T-shaped toothed rod 6 is engaged with the semi-circular gear 27. The semi-circular gear 27 is fixedly connected to the output end of the first motor 11. The first motor 11 is fixedly connected in the main body 1 of the system.

[0029] The upper end of the mounting frame 7 is equipped with a heating tube 12. By turning on the two sets of heating tubes 12, heat is generated, which can make the blown air have a corresponding temperature. The heating tube 12 is fixedly connected to the ventilation cavity 23. A fan 14 is provided on the upper side of the heating tube 12. The fan 14 is fixedly connected to the output end of the second motor 13. When the second motor 13 is turned on, it drives the fan 14 to start rotating. The fan 14 rotates and draws the outside air into the prefabricated toilet. By controlling the second motor 13 to reverse, the air in the prefabricated toilet can be extracted. The second motor 13 is fixedly connected to the system body 1. The upper end of the system body 1 is fixedly connected to the ventilation hose 16 by bolts 17. The lower end of the T-shaped locking rod 21 is fixedly connected to the lever 20. The end of the lever 20 away from the T-shaped locking rod 21 passes through the slide groove 19 and extends out of the liquid storage box 5.

[0030] In addition, to achieve the above objectives, the present invention also provides a bathroom, including the above-described prefabricated bathroom ventilation system.

[0031] Working principle: When in use, after the top of the prefabricated bathroom is assembled, the main body 1 of the system is installed on the top of the prefabricated bathroom by several sets of screws 32. The ventilation hose 16 is connected to the main body 1 of the system by bolts 17. At this time, the fresh air ventilation system is installed. When ventilation is required in the prefabricated bathroom, the second motor 13 is turned on to drive the fan 14 to start rotating. The fan 14 rotates and draws the outside air into the ventilation hose 16. After the air enters the ventilation cavity 23, it passes through the mounting frame 7 and is discharged into the prefabricated bathroom. By controlling the second motor 13 to reverse, the air in the prefabricated bathroom can be extracted.

[0032] By turning on the two sets of heating tubes 12 to generate heat, the blown air can be made to have a corresponding temperature. When the smell in the prefabricated bathroom is unpleasant, you can add your favorite fragrance liquid to the liquid storage box 5. After adding, push the liquid storage box 5 into the installation cavity 2. At the same time, during the pushing process, insert the second protective tube 15 set in the installation cavity 2 into the liquid storage box 5, and ensure that the guide rods 4 set at both ends of the liquid storage box 5 move along the guide groove 3. Press the two sets of levers 20 inward and move them along the slide groove 19. When the levers 20 move, they drive the T-shaped locking rod 21 to move inward along the sliding cavity 18. At this time, the first spring 31 is compressed. When the liquid storage box 5 is pushed into the bottom of the installation cavity 2, release the pressure on the two sets of levers 20. Under the elastic force of the first spring 31;

[0033] Two sets of T-shaped locking rods 21 will engage with the corresponding locking grooves 22. At this time, the installation of the liquid storage box 5 is completed. When the absorbent cotton strip 28 in the second protective tube 15 absorbs the fragrance liquid in the liquid storage box 5, the fragrance liquid enters the movable plate 8 along the absorbent cotton strip 28. At this time, the first motor 11 is turned on to drive the semi-circular gear 27 to start rotating. The rotation of the semi-circular gear 27 drives the T-shaped gear 6 to move towards the position of the second spring 26. At this time, the movable plate 8 begins to swing in one direction under the mutual cooperation of the teeth 10 and the T-shaped gear 6. When the semi-circular gear 27 disengages from the T-shaped gear 6;

[0034] At this time, under the elastic force of the second spring 26, the T-shaped gear 6 returns to its original position, and the movable plate 8 will swing in the opposite direction. When the semi-circular gear 27 contacts the T-shaped gear 6 again, the movable plate 8 will swing again. Since one end of the absorbent cotton strip 28 is fixed to the movable plate 8, the absorbent cotton strip 28 will be rotated and squeezed during the back-and-forth swing of the movable plate 8, so that the fragrance liquid in the absorbent cotton strip 28 is quickly discharged and re-absorbed into the sponge 9. At this time, when the fan 14 drives the airflow into the prefabricated bathroom, the fragrance liquid in the sponge 9 is discharged into the airflow through the through hole 29. At this time, the fragrant air will improve the air in the prefabricated bathroom.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
