[0001] This invention relates to the field of household appliance technology, and in particular to electric heating hanging rods, hanging rod bases, and electric heating hanging racks. Background Technology

[0002] Towel racks are primarily used for drying towels, but other clothing can also be hung on them to dry. To enhance the drying capacity of towel racks, multiple hanging rods can be installed, and even heated rods can be incorporated to further accelerate the drying process. However, for towel racks with sliding hanging rods, it is difficult to guarantee the reliable power supply of the heating element if it is installed within the rod. Summary of the Invention

[0003] Therefore, it is necessary to address the issue of insufficient reliability of the heating element's power supply in situations where the hanging rod can slide. This requires providing an electric heating hanging rod, a hanging rod base, and an electric heating hanging rack. The electric heating hanging rod slides on the slide rail via a clamping groove. When the electric heating hanging rod slides to the appropriate position, the conductive part aligns with the corresponding electrical contact groove. Under the action of the retaining member, the conductive part can be reliably pressed against the electrical contact member, thereby ensuring a reliable electrical connection between the heating element and the power source.

[0016] In one embodiment, the length direction of the rod body intersects the axial direction of the fixed cylinder, and the rod body is provided with a mounting cavity for mounting the heating element. The mounting cavity communicates with the space inside the fixed cylinder, and the heating element or the conductive wire passes through the mounting cavity and the connection point between the fixed cylinder and the heating element.

[0017] The position on the fixed cylinder that connects to the rod body is the connection position. The pressure-bearing part is disposed on the outer peripheral surface of the fixed cylinder. In the first direction, the pressure-bearing part is located on one side of the connection position. The sliding cylinder is located on the side of the connection position close to the pressure-bearing part. One end of the sliding cylinder away from the connection position is located outside the fixed cylinder. The pressure-applying part is disposed on the outer peripheral surface of the sliding cylinder at this end outside the fixed cylinder.

[0018] In one embodiment, the electric heating rod further includes a drive shaft and a button. The button is mounted on the fixed cylinder at one end away from the pressure-applying part. The drive shaft is located inside the fixed cylinder and is connected between the button and the sliding cylinder. The elastic element acts between the button and the fixed cylinder, and the direction of the force provided by the elastic element to the button is consistent with the direction from the pressure-applying part to the pressure-receiving part.

[0019] A hanging rod holder, comprising:

[0020] power supply;

[0021] The slide rail has multiple electrical contact grooves, which are spaced apart along the guide direction of the slide rail. The bottom wall of each electrical contact groove is provided with an electrical contact element, and the power source is electrically connected to each of the electrical contact elements.

[0022] In one embodiment, the slide rail has a receiving cavity for accommodating the electrical contact, the electrical contact groove extends through the receiving cavity along its depth direction, and the receiving cavity also has a placement opening located on the side of the slide rail, the length direction of the side where the placement opening is located is consistent with the guide direction of the slide rail;

[0023] The slide rail is also provided with a track cover, which is located on the side of the slide rail where the placement opening is located and covers the placement opening. The track cover is slidably engaged with the slide rail.

[0024] In one embodiment, the hanging rod base includes two slide rails, which are arranged parallel and spaced apart, and the spacing direction of the two slide rails is perpendicular to the depth direction of the electrical contact groove.

When it is necessary to adjust the position of the electric heating hanging rod on the hanging rod base, the sliding lock unit is first adjusted to the loose state by external force, and the conductive part is disengaged from the electrical receiving groove. Then, the electric heating hanging rod is slid along the guide direction of the slide rail. When it slides to the appropriate position, the conductive part is aligned with the corresponding electrical receiving groove. Then, the external force is removed, and the sliding lock unit returns to the clamping state under the action of the retaining member, and the conductive part is inserted into the electrical receiving groove. Under the action of the retaining member, the conductive part can be reliably pressed against the electrical receiving part, thereby ensuring a reliable electrical connection between the heating element and the power supply.

Detailed Implementation

[0042] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] like Figure 1 and Figure 2 As shown, in some embodiments of this application, an electrically heated hanging rod 10 is provided, including a rod body 11 and a sliding lock unit 12. The rod body 11 is provided with a heating element 111, which can be a carbon fiber device or a silicone heating sheet, etc.

[0044] The sliding lock unit 12 includes a fixing member 121 and a sliding member 122. The fixing member 121 is connected to the rod body 11, and the sliding member 122 slides and engages with the fixing member 121 in a first direction, so that there are clamping and loosening states between the two.

[0045] The slide lock unit 12 further includes a retainer 125, which acts between the fixing member 121 and the sliding member 122 to provide a force for the sliding member 122 to be held in the clamping state.

[0046] The fixing member 121 includes a pressure-receiving part 123, and the sliding member 122 includes a pressure-applying part 124. The pressure-receiving part 123 and the pressure-applying part 124 are arranged at intervals in the first direction to form a clamping groove 1241. In the clamping state, the distance between the pressure-receiving part 123 and the pressure-applying part 124 is smaller than the distance between the pressure-receiving part 123 and the pressure-applying part 124 in the loosening state. The side wall of the clamping groove 1241 is provided with a conductive part 126, and the conductive part 126 is electrically connected to the heating member 111.

[0047] In use, the electric heating rod 10 can be slidably mounted on the rod holder 20 via the clamping groove 1241. When it is necessary to slide relative to the rod holder 20, the sliding lock unit 12 is adjusted to the loose state. At this time, the distance between the pressure receiving part 123 and the pressure applying part 124 is large, in other words, the distance between the two side walls of the clamping groove 1241 is large, so it can slide relative to the rod holder 20. When the electric heating rod 10 slides to a suitable position, the sliding lock unit 12 is adjusted to the clamping state. At this time, the distance between the pressure receiving part 123 and the pressure applying part 124 is small. Under the action of the retaining member 125, the rod holder 20 is clamped between the pressure receiving part 123 and the pressure applying part 124. At the same time, the conductive part 126 is pressed onto the rod holder 20 to achieve electrical connection, which improves the reliability of electrical connection in applications where the electric heating rod 10 can slide.

[0048] Specifically, the conductive part 126 can be a protruding structure provided on the side wall of the clamping groove 1241, or it can be a recessed structure provided on the side wall of the clamping groove 1241.

[0049] like Figure 1 and Figure 2 As shown, in some embodiments, the conductive part 126 includes a conductive protrusion disposed on the side wall of the clamping groove 1241, the conductive protrusion being electrically connected to the heating element 111.

[0050] Furthermore, in some cases, multiple conductive parts 126 can be provided on the side wall of the clamping groove 1241, such as... Figure 1 and Figure 2 In the embodiment shown, two conductive parts 126 are provided on the side wall of the clamping groove 1241. One of the conductive parts 126 is a positive terminal connector 1261, and the other conductive part 126 is a negative terminal connector 1262. The heating element 111 is electrically connected between the positive terminal connector 1261 and the negative terminal connector 1262. When the positive terminal connector 1261 and the negative terminal connector 1262 are connected to the power supply 21, a power-conducting circuit is formed.

[0051] Specifically in one embodiment, such as Figure 2 As shown, the two conductive parts 126 are arranged at intervals along the length of the rod body 11.

[0052] like Figure 6 As shown, when the electric heating rod 10 is installed on the rod holder 20, the two conductive parts 126 correspond to the electrical receiving grooves 221 on the two slide rails 22 respectively, and the two conductive parts 126 are respectively used to electrically connect with the electrical receiving parts 222 in the corresponding electrical receiving grooves 221.

[0053] Furthermore, such as Figure 1As shown, in one embodiment, the sidewall of the clamping groove 1241 is further provided with a plurality of positioning protrusions 13, which are spaced apart. The conductive protrusions are also spaced apart from the positioning protrusions 13. Thus, when the hanging rod seat 20 is clamped in the clamping groove 1241, the presence of multiple protruding structures cooperating with the hanging rod seat 20 can restrict the rotation of the electric heating hanging rod 10 relative to the hanging rod seat 20, making the positioning more stable.

[0054] like Figure 1 As shown, in some embodiments, the outer perimeter of the surface of the pressure-applying part 124 facing the pressure-receiving part 123 forms a rounded rectangle, and the outer perimeter of the surface of the pressure-receiving part 123 facing the pressure-applying part 124 forms a rounded rectangle. Two positioning protrusions 13 are located at two corners of the rounded rectangle, and two conductive parts 126 are located at the other two corners of the rounded rectangle.

[0055] In some embodiments, such as Figure 2 As shown, the retaining member 125 is an elastic member, the deformation direction of the elastic member is consistent with the first direction, and the force provided by the elastic member to the sliding member 122 is consistent with the direction from the pressure-applying part 124 to the pressure-receiving part 123. Figure 2 The direction of the middle arrow N1 is the first direction.

[0056] Without external force, the sliding member 122 and the fixed member 121 remain in a clamped state under the action of the elastic member.

[0057] When the electric heating rod 10 needs to be slidable, an external force is applied to the sliding member 122 to overcome the elastic force of the elastic member, so that the sliding member 122 and the fixing member 121 switch to a loose state.

[0058] Optionally, the retainer 125 can also be other devices, as long as they can provide a force to hold the slider 122 in the clamping state. For example, the retainer 125 can be a snap-fit ​​assembly disposed between the slider 122 and the fixing member 121. When it is necessary to slide the electric heating rod 10, the snap-fit ​​assembly is released, and the slider 122 is moved relative to the fixing member 121, thereby switching the two to a loose state. When it is necessary to clamp the electric heating rod 10 after it has slid to the target position, the snap-fit ​​assembly is fastened, so that the electric heating rod 10 is held in the clamping state.

[0059] In some embodiments, such as Figure 1 and Figure 2 As shown, the fixing member 121 includes a fixing cylinder, the pressure-bearing part 123 is connected to the fixing cylinder, and the rod body 11 is connected to the fixing cylinder;

[0060] The sliding member 122 includes a sliding cylinder, the pressure applying part 124 is connected to the sliding cylinder, and the fixed cylinder is slidably sleeved outside the sliding cylinder. The axial directions of both the fixed cylinder and the sliding cylinder are consistent with the first direction. The fixed cylinder and the sliding cylinder slide relative to each other in the axial direction, thereby switching states.

[0061] Specifically in some embodiments, such as Figure 1 and Figure 2 As shown, the pressure-receiving part 123 is disposed on the outer peripheral surface of the fixed cylinder, and the pressure-applying part 124 is disposed on the outer peripheral surface of the sliding cylinder. The portion of the sliding cylinder connected to the pressure-applying part 124 is located outside the fixed cylinder. The pressure-applying part 124 and the pressure-receiving part 123 are used to form two opposite sidewalls of the clamping groove 1241, and the sliding cylinder is used to form the bottom wall of the clamping groove 1241. The clamping groove 1241 is distributed around the periphery of the sliding cylinder.

[0062] The elastic element acts directly or indirectly between the fixed cylinder and the sliding cylinder, providing the sliding cylinder with an elastic force that slides axially relative to the fixed cylinder, and the direction of this elastic force is consistent with the direction from the pressure-applying part 124 to the pressure-receiving part 123.

[0063] Furthermore, such as Figure 2 As shown, a conductive wire 1111 is electrically connected between the heating element 111 and the conductive part 126, and the conductive wire 1111 passes through the fixed cylinder and the sliding cylinder. The conductive wire 1111 is routed through the space between the fixed cylinder and the sliding cylinder to avoid the conductive wire 1111 being exposed.

[0064] In some embodiments, such as Figure 1 and Figure 2 As shown, the length direction of the rod body 11 intersects the axial direction of the fixed cylinder. For example, in some embodiments, the length direction of the rod body 11 is perpendicular to the axial direction of the fixed cylinder.

[0065] The rod body 11 has a mounting cavity 112 for mounting the heating element 111. The mounting cavity 112 communicates with the space inside the fixed cylinder. The heating element 111 or the conductive wire 1111 passes through the mounting cavity 112 and communicates with the fixed cylinder.

[0066] The position on the fixed cylinder that connects to the rod body 11 is the connection position 1211. The pressure-receiving part 123 is disposed on the outer peripheral surface of the fixed cylinder. In the first direction, the pressure-receiving part 123 is located on one side of the connection position 1211. The sliding cylinder is located on the side of the connection position 1211 close to the pressure-receiving part 123. One end of the sliding cylinder away from the connection position 1211 is located outside the fixed cylinder. The pressure-applying part 124 is disposed on the outer peripheral surface of the sliding cylinder at the end located outside the fixed cylinder.

[0067] When the sliding cylinder slides relative to the fixed cylinder, the sliding cylinder is located on the side of the connection position 1211, so the sliding cylinder will not interfere with the heating element 111 or the conductive line 1111.

[0068] Furthermore, in some embodiments, such as Figure 2 As shown, the electric heating rod 10 also includes a drive shaft 14 and a button 15. The button 15 is mounted on the fixed cylinder at one end away from the pressure-applying part 124. The drive shaft 14 is located inside the fixed cylinder and is connected between the button 15 and the sliding cylinder. The elastic element acts between the button 15 and the fixed cylinder. The direction of the force provided by the elastic element to the button 15 is consistent with the direction from the pressure-applying part 124 to the pressure-receiving part 123.

[0069] By pressing button 15 at one end of the fixed cylinder, the elastic force of the elastic element is overcome, causing the drive shaft 14 to slide relative to the fixed cylinder with the sliding cylinder, switching to the released state. When the force of pressing button 15 is released, under the action of the elastic element, button 15 slides relative to the fixed cylinder, the drive shaft 14 moves with button 15, and the sliding cylinder slides relative to the fixed cylinder under the drive of the drive shaft 14, switching to the clamping state.

[0070] like Figure 3 and Figure 4 As shown, in some embodiments of this application, a hanging rod holder 20 is provided, including:

[0071] Power supply 21;

[0072] The slide rail 22 is provided with a plurality of electrical contact grooves 221, which are arranged at intervals along the guide direction of the slide rail 22. The bottom wall of the electrical contact groove 221 is provided with an electrical contact element 222, and the power supply 21 is electrically connected to each of the electrical contact elements 222.

[0073] The electric heating rod 10 is slidably fitted onto the slide rail 22 via the clamping groove 1241, such as... Figure 6 As shown, in the detached state, the distance between the pressure-applying part 124 and the pressure-receiving part 123 of the electric heating rod 10 is relatively large, and the conductive part 126 is retracted outside the electrical contact groove 221. At this time, the electric heating rod 10 can slide along the slide rail 22. Figure 7 As shown, the distance between the pressure-applying part 124 and the pressure-receiving part 123 of the electric heating rod 10 in the clamped state is small. The slide rail 22 is clamped between the pressure-applying part 124 and the pressure-receiving part 123, and the conductive part 126 protrudes into the electrical contact groove 221. The conductive part 126 is electrically connected to the electrical contact member 222, thereby making the heating element 111 electrically connected to the power supply 21.

[0074] When the electric heating rod 10 slides to the appropriate position and switches to the clamping state, the conductive part 126 and the electrical receiving groove 221 engage with each other, which not only improves the positional stability of the electric heating rod 10 on the rod holder 20, but also provides an electrical receiving element 222 on the bottom wall of the electrical receiving groove 221. The force provided by the retaining member 125 to the sliding member 122 can also ensure that the conductive part 126 and the electrical receiving element 222 are in close contact to a certain extent, thus improving the reliability of the electrical connection.

[0075] Furthermore, in some embodiments, such as Figure 4 As shown, the slide rail 22 has a receiving cavity 223 for accommodating the electrical connector 222. The electrical connector groove 221 extends through the receiving cavity 223 along its depth direction. The receiving cavity 223 also has a placement opening 2231 located on the side of the slide rail 22. The length direction of the side where the placement opening 2231 is located is consistent with the guiding direction of the slide rail 22. During installation, the electrical connector 222 can be inserted into the receiving cavity 223 from the placement opening 2231 until the electrical connector 222 is pushed to the position where the electrical connector groove 221 communicates with the receiving cavity 223. To a certain extent, the electrical connector 222 can be regarded as the bottom wall of the electrical connector groove 221.

[0076] Furthermore, in some embodiments, such as Figure 4 As shown, the slide rail 22 is also provided with a track cover 23. The track cover 23 is disposed on the side of the slide rail 22 where the placement opening 2231 is located and covers the placement opening 2231. The track cover 23 is slidably engaged with the slide rail 22. After the electrical connector 222 is installed, the track cover 23 is installed on the slide rail 22, and the placement opening 2231 is covered by the track cover 23 to prevent the electrical connector 222 from falling out.

[0077] like Figure 3 and Figure 4 As shown, in one embodiment, the accommodating cavity 223 is an elongated space, the length of which is aligned with the guiding direction of the slide rail 22. Each electrical contact groove 221 extends into the accommodating cavity 223 along its depth direction. The placement opening 2231 is an elongated opening provided along the guiding direction of the slide rail 22. The track cover 23 slides along the guiding direction of the slide rail 22.

[0078] In some embodiments, such as Figure 3 , Figures 6 to 8 As shown, the hanging rod seat 20 includes two slide rails 22, which are arranged in parallel and spaced apart, and the spacing direction of the two slide rails 22 is perpendicular to the depth direction of the power receiving groove 221;

[0079] The hanging rod seat 20 also includes a rear cover 24 and a track bracket 25. The track bracket 25 is connected to the rear cover 24. Two slide rails 22 are both arranged on the track bracket 25, and each slide rail 22 is spaced apart from the rear cover 24. The slot of the power receiving groove 221 faces the rear cover 24.

[0080] like Figure 6 and Figure 7 As shown, when the electric heating rod 10 is installed on the rod holder 20, the pressure-applying part 124 is located in the gap between the slide rail 22 and the rear cover 24, and the pressure-receiving part 123 is located on the side of the slide rail 22 away from the rear cover 24. The fixing member 121 and the sliding member 122 are inserted into the space between the two rails. When the sliding member 122 slides relative to the fixing member 121, the distance between the pressure-applying part 124 and the pressure-receiving part 123 changes, realizing the state switching.

[0081] like Figure 6 As shown, the pressure-bearing part 123 presses against the side of the track bracket 25 facing away from the rear cover 24. When the button 15 is pressed, the button 15 moves downward against the elastic force of the elastic member, the drive shaft 14 moves downward synchronously with the button 15, the sliding member 122 moves relative to the fixed member 121 under the drive of the drive shaft 14, the pressure-applying part 124 moves downward, and the conductive part 126 retracts from the electrical receiving groove 221. Without the restraining effect of the interlocking action between the conductive part 126 and the electrical receiving groove 221, the electric heating rod 10 can slide along the slide rail 22.

[0082] like Figure 7 As shown, when the electric heating rod 10 slides to the appropriate position, the force of pressing the button 15 is released. The button 15 and the drive shaft 14 move upwards under the reset action of the elastic element, the sliding member 122 moves upwards, and the conductive part 126 is inserted into the electrical receiving groove 221 and pressed together with the electrical receiving member 222, thus electrically connecting the conductive part 126 to the electrical receiving member 222. The appropriate position of the electric heating rod 10 described here has at least the following characteristics: the conductive part 126 is directly opposite the electrical receiving groove 221. Thus, under the action of the elastic element, the conductive part 126 can be inserted into the electrical receiving groove 221 and electrically connected to the electrical receiving member 222.

[0083] Furthermore, such as Figure 7 and 8 As shown, the space between the two slide rails 22 and the space between the slide rail 22 and the back cover 24 form a groove 26, and the groove 26 passes through the track bracket 25 along the guide direction of the slide rail 22.

[0084] The hanging rod seat 20 also includes an end housing 27, which is detachably mounted on the rear cover 24 and located at one end of the slide rail 22. The power supply 21 is installed in the end housing 27.

[0085] When it is necessary to add, replace or remove the electric heating rod 10, the end housing 27 can be removed from the rear cover 24, so that the end of the slide rail 22 is exposed, and the electric heating rod 10 slides out from the end of the slide rail 22 or slides into the slide groove 26.

[0086] After the electric heating rod 10 is installed in place, the end housing 27 is then installed onto the rear cover 24, as follows. Figure 5 and Figure 8 As shown, the electric heating rod 10 will not slide out of the slide rail 22 under the limiting action of the end housing 27.

[0087] In some embodiments of this application, an electrically heated hanging rack 30 is provided, such as... Figures 5 to 8 As shown, it includes the electric heating rod 10 described in any of the above claims and the rod holder 20 described in any of the above claims. For example... Figure 2 and Figure 3 As shown, the electric heating rod 10 is slidably fitted onto the slide rail 22 via the clamping groove 1241. One of the conductive parts 126 in the two side walls of the clamping groove 1241 faces the surface of the slide rail 22 where the electrical receiving groove 221 is provided. In the clamping state, the slide rail 22 is clamped in the clamping groove 1241, the conductive part 126 is located in the electrical receiving groove 221, and the conductive part 126 is electrically connected to the electrical receiving element 222.

[0088] The above solution provides an electric heating hanging rod 10, a hanging rod base 20, and an electric heating hanging rack 30. The electric heating hanging rod 10 is slidably engaged with the slide rail 22 via the clamping groove 1241. When it is necessary to adjust the position of the electric heating hanging rod 10 on the hanging rod base 20, the sliding lock unit 12 is first adjusted to a loose state by external force, and the conductive part 126 is disengaged from the electrical receiving groove 221. Then, the electric heating hanging rod 10 is slid along the guide direction of the slide rail 22. When it slides to a suitable position, the conductive part 126 is aligned with the corresponding electrical receiving groove 221. Then, the external force is removed, and the sliding lock unit 12 returns to the clamping state under the action of the retaining member 125, and the conductive part 126 is inserted into the electrical receiving groove 221. Under the action of the retaining member, the conductive part 126 can be reliably pressed against the electrical receiving member 222, thereby ensuring a reliable electrical connection between the heating element 111 and the power supply 21.
