The disadvantage is that the air outlet is generally open, and water vapor in the bathroom can easily enter the shell cavity from the air outlet, which can easily cause damage to the various functional mechanisms in the cavity and shorten the service life. Some companies install louvers at the air outlet, etc., but their sealing is limited and needs to be improved. Utility Model Content

[0003] To solve at least one of the above technical deficiencies, the present invention provides the following technical solutions:

[0004] The present application document discloses a bathroom heater, comprising a shell, an air outlet being arranged at the bottom surface of the shell and panels being arranged at opposite sides of the air outlet, and a sealing mechanism, wherein the sealing mechanism comprises a driving mechanism, a sealing plate, an elastic layer 1 and an elastic layer 2. The driving mechanism is arranged at the side surface of the shell, and the two sealing plates are correspondingly sleeved on the panels and slidably fitted. An elastic layer 1 is arranged at the head end and the tail end of the sealing plate and the elastic layer 1 abuts against the corresponding circumferential surface of the panel. An elastic layer 2 is arranged at the bottom of both sides of the sealing plate between the elastic layer 1 and the elastic layer 2 abuts against the shell surface. The driving mechanism is connected to the two sealing plates to drive them to move to close or open the air outlet.

[0005] In this solution, a sealing mechanism is added to the heater shell, a driving mechanism is installed on the side of the shell, and a sealing plate is installed on the panel at the bottom of the shell. The driving mechanism drives the sealing plates to move toward each other to a merged state, thereby forming a seal on the air outlet of the shell to prevent water vapor from the bathroom from entering and extend the service life. When the driving mechanism drives the sealing plates to move away from each other to an open state at the air outlet, hot air in the heater flows out from the air outlet. The sealing mechanism is external, which is convenient for modifying existing heaters.

[0006] Furthermore, the driving mechanism includes a fixed box, a driving motor, a transmission mechanism, a screw, a nut, and a connecting rod.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figure 1 、 Figure 2As shown, in this example, a bathroom heater includes a shell 1, which is shaped like a common rectangular box. Various functional mechanisms are installed in the shell 1, and an air outlet 3 is formed in the middle position of the bottom surface of the shell 1. Panels 2 are installed on the bottom surface of the shell 1 on both sides opposite to the air outlet 3. This is a conventional shape of a bathroom heater and will not be elaborated here.

[0022] In this example, a sealing mechanism is added, which includes a driving mechanism, a sealing plate 6, an elastic layer 1 7, and an elastic layer 2 8. Figure 1 As shown, the drive mechanism is mounted on the side of the housing 1. The two sealing plates 6 are both slot-shaped, and each sealing plate 6 is slidably fitted over the corresponding panel 2. For the sliding connection of the sealing plates, for example, grooves are formed along the length of the two sides of the panel 2, and the ridges on the side walls of the sealing plates 6 are positioned within the grooves to form a sliding connection.

[0023] The head and tail ends of the sealing plate 6 are covered with an elastic layer 7, such as a rubber material. When the two sealing plates 6 are in contact, the elastic layer 7 contacts to improve the sealing performance, and the elastic layer 7 contacts the corresponding circumferential surface of the shell 1 to improve the sealing performance.

[0024] The elastic layer 2 8 is covered on the bottom of both sides of the sealing plate 6 between the elastic layer 1 7, and the elastic layer 2 8 is abutted against the corresponding peripheral surface of the shell 1. Under this configuration, the two sealing plates 6 form a relatively sealed space after abutting, thereby improving the sealing of the air outlet and reducing the entry of water vapor.

[0025] The driving mechanism is connected to the two sealing plates 6 to drive them to move to close or open the air outlet 3. For the driving mechanism, the driving mechanism includes a fixing box 4, a driving motor 9, a transmission mechanism 10, a screw 11, a nut 12, and a connecting rod 5. The fixing box is a common rectangular box. The fixing box 4 is installed on the side of the housing 1 by bolts or screws. Figure 1 shown.

[0026] The drive motor 9 and the screw 11 are installed in the fixed box 4. Figure 2 As shown, the drive motor 9 and the screw 11 are arranged along the length direction of the box body, and a seat body 14 is formed in the box body cavity. The screw 11 is rotatably connected to the seat body 14 through bearings, etc. The screw 11 is a coaxial double-helix type, and the surfaces with different rotation directions are located at both ends of the screw 11. Nuts 12 are installed at both ends. The two connecting rods 5 are coaxially arranged with the screw 11, and the nuts 12 are fixed in the notches of the grooves 13 formed at the ends of the connecting rods 5. The corresponding ends of the screws extend into the grooves and are connected to the nuts.

[0027] A guide hole, such as a rectangular hole, is formed on the wall of the fixed box 4, and the corresponding connecting rod 5 is a rectangular rod body. The connecting rod 5 extends from the guide hole to guide the movement of the connecting rod and limit the rotation of the connecting rod 5. The end of the connecting rod 5 outside the fixed box 4 is connected to the corresponding sealing plate 6.

[0028] The output end of the drive motor 9 is connected to the screw 11 through the transmission mechanism 10. The transmission mechanism 10 is a double-gear type, one gear of which is fixed at the output end of the drive motor 9, and the other gear is fixed on the screw 11. When the drive motor 9 is started, the screw is driven to rotate under the transmission of the transmission mechanism, which correspondingly moves the connecting rod and synchronously drives the sealing plates to move toward or away from each other. If they move toward each other until the two sealing plates abut against each other, a seal is formed on the air outlet, which helps to reduce the ingress of water vapor in the bathroom and thereby extend the service life of the heater.

[0029] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
